Occupational Health and Safety (OHS) refers to the legislation, policies, procedures and activities that aim to protect the health, safety and welfare of all people at the workplace.

Every worker has a right to healthy and safe work and to a work environment that enables them to live a socially and economically productive life. Safety practices should be learned early and always adhered to when working with any electrical device including personal computers and peripherals.

Personal safety while working with PC’s

Here are some safety precautions to take before working with any computer devices:

• Before doing anything, listen to your teacher’s instruction to prevent accidents or any unwanted events that may occur on your workplace.

• Do not work on computer when you are wet because you might get electrocuted. • Do not remove internal devices of the computer when it is turned on. • Be sure not to mix electronic components and water. • Avoid playing or running while inside the room. • Always wear personal protective equipments (PPE) like coverall, shoes with rubber

sole, anti-static wrist strap, etc. • Ask for assistance from your teacher when it comes on dealing with computer

devices. • Applying safety measure when handling tools and equipment are necessary to

avoid certain damages.

The student is further expected to maintain good health, to be neat in personal appearance and to practice safe working procedures at all time with appropriate equipment.

A computer network is an interconnected group of computers.

Computer Network

In general, the term network can refer to any interconnected group or system. More specifically, a network is any method of sharing information between two systems (human or mechanical).

BENEFITS OF SHARING INFORMATION VIA NETWORK

In addition to reducing hardware costs by sharing expensive printers and other peripherals among multiple users, networks provide additional benefits to the users.

Software and data files can be shared for access by multiple users Electronic mail e-mail can be sent and received Collaboration features allow contributions by multiple users to a single document Remote-control programs can be used to troubleshoot problems or show new users

how to perform a task

SHARED HARDWARE COMPONENTS

Virtually, any storage or output device can be shared over a network, but the most common devices to be used over a network include:

Printers Disk drives CD-ROM and optical drives Modems Fax Tape backup units

Network Topology signifies the way in which intelligent devices in the network see their logical relations to one another. The use of the term "logical" here is significant. That is, network topology is independent of the "physical" layout of the network. Even if networked computers are physically placed in a linear arrangement, if they are connected via a hub, the network has a Star topology, rather than a Bus Topology. In this regard the visual and operational characteristics of a network are distinct; the logical network topology is not necessarily the same as the physical layout.

network topology

• Bus Topology

It is often used when network installation is small, simple or temporary. On a typical bus network the cable is just 1 or more wires with no active electronics to amplify the signal or pass it along from computer to computer. This makes the bus a passive topology. When 1 computer sends a signal up the wire all the computers receive the information but only one with the address that matches accepts the information, the rest disregard the message.

Bus Topology

Advantages:

1) Easy to use and to understand. 2) Requires least amount of cable to connect the computers together. It is therefore

less expensive than other cabling arrangements. 3) It is easy to extend a bus; two cables can be joined into 1 longer cable with a BNC,

Barrel connector making a longer cable and allowing more computers to join the network.

11 | P a g e


Disadvantages:

1) Heavy network traffic can slow a bus considerably as only 1 computer can send a message at a time.

2) It is difficult to troubleshoot the bus. A cable break or loose connector causes reflection and stops all the activity.

• STAR TOPOLOGY

In this kind of topology all the cables run from the computers to the central location where they are all connected by a device called hub or switch. Each computer on a star network communicates with a central device that resends the message either to each computer or only to the destination computer, example if it is a hub then it will send to all and if it is a switch then it will send to only destination computer. When network expansion is expected and when the greater reliability is needed, star topology is the best.

Star Topology

Advantages:

1) It is easy to modify and add new computers without disturbing the rest of the network.

2) The center of the star network is a good place to diagnose the faults. 3) Single computer failure does not necessarily bring down the whole star network.

Disadvantages:

1) If the central device fails, the whole network fails to operate. 2) Star networking is expensive because all network cables must be pulled to one

central point, requires more cable than other network topologies.

12 | P a g e


• RING TOPOLOGY

In this type each computer is connected to the next computer with the last one connected to the first. Each retransmits what it receives from the previous computer. The message flows around the ring in one direction. The ring network does not subject to signal loss problem as a bus network experiences. There is no termination because there is no end to the ring.

Ring Topology

Advantages:

1) Each node has equal access. 2) Capable of high speed data transfer.

Disadvantages:

1) Failure of one computer on the ring can affect the whole network. 2) Difficult to troubleshoot the network.

•

Types of networks

Below is a list of the most common types of computer networks in order of scale.

A personal area network (PAN) is a computer network used for communication among computer devices close to one person. Some examples of devices that may be used in a PAN are printers, fax machines, telephones, PDA’s or scanners. The reach of a PAN is typically within about 20-30 feet (approximately 6-9 meters).

Personal Area Network (PAN)

13 | P a g e


Personal area networks may be wired with computer buses such as USB] and FireWire. A wireless personal area network (WPAN) can also be made possible with network technologies such as Bluetooth.

Personal Area Network

•

A network covering a small geographic area, like a home, office, or building. Current LANs are most likely to be based on Ethernet technology. For example, a library will have a wired or wireless LAN for users to interconnect local devices (e.g., printers and servers) and to connect to the internet. All of the PCs in the library are connected by

Local Area Network (LAN)

category 5 (Cat5) cable, running the IEEE 802.3 protocol through a system of interconnection devices and eventually connect to the internet. The cables to the servers are on Cat 5e enhanced cable, which will support IEEE 802.3 at 1 GB/s.

The staff computers (bright green) can get to the color printer, checkout records, and the academic network and the Internet. All user computers can get to the Internet and the card catalog. Each workgroup can get to its local printer. Note that the printers are not accessible from outside their workgroup.

Client/Server Vs Peer-to-Peer Networks

Although every computer on a LAN is connected to every other, they do not necessarily mean all communicate with each other. There are two basic types of LAN, based on communication patterns between the machines, called client/server networks and peer-to-peer networks.

Client/Server Networks

Every computer has a distinct role, that of either a client or a server. A server is designed to share its resources among client computers on the network. The Client/Server is composed of:

Servers

− These are located in secured areas, such as locked closets and data centers, because they hold the organization's most valuable data and do not have the accessed by operators on a continuous basis.

− The server runs a special network operating system such as: Windows NT Server, Windows 2000 or Novell Netware.

Clients

− The rest of the computers on the network functions as client. A client standard PC that is running an operating system such as DOS or Windows.

Hub

Server

Client

15 | P a g e


Example of Client/Server

Peer-to-Peer Network

In a peer-to-peer network, every computer is equal and can communicate with other computer on a network to which it has been granted access rights. Essentially, every computer in this network functions as both server and client. Peer-to-peer network can be as small as two computers as many as hundreds of units.

There is no theoretical limit to the size of a peer-to-peer network, performance drops significantly and security becomes a major headache on peer -based network with more than 10 computers. Also, Microsoft imposes a 10-station limit on computers running Windows 2000 Professional who are sharing resources with other system. For this reason, it is better you switch to a client/server network when your network climbs to 10 stations.

Example of Peer-to-Peer Network

CAMPUS AREA NETWORK (CAN)

A network that connects two or more LANs but that is limited to a specific and contiguous geographical area such as a college campus, industrial complex, or a military base. A CAN may be considered a type of MAN (metropolitan area network), but is generally limited to an area that is smaller than a typical MAN. This term is most often used

16 | P a g e


to discuss the implementation of networks for a contiguous area. This should not be confused with a Controller Area Network.

Campus Area Network

A Metropolitan Area Network is a network that connects two or more Local Area Networks or Campus Area Networks together but does not extend beyond the boundaries of the immediate town, city, or metropolitan area. Multiple routers, switches & hubs are connected to create a MAN.

Metropolitan Area Network (MAN)

Metropolitan Network

A WAN is a data communications network that covers a relatively broad geographic area (i.e. one city to another and one country to another country) and that often uses transmission facilities provided by common carriers, such as telephone companies. WAN technologies generally function at the lower three layers of the

Wide Area Network (WAN)

OSI reference model: the physical layer, the data link layer, and the network layer.

Wide Area Network

Global area networks (GAN) specifications are in development by several groups, and there is no common definition. In general, however, a GAN is a model for supporting mobile communications across an arbitrary number of wireless LANs, satellite coverage areas, etc. The key challenge in mobile communications is "handing off" the user communications from one local coverage area to the next. In IEEE Project 802, this involves a succession of terrestrial

Global Area Network (GAN)

Wireless local area networks (WLAN).

Global Area Network

http://en.wikipedia.org/wiki/Wireless_LAN�

18 | P a g e


Two or more networks or network segments connected using devices that operate at layer 3 (the 'network' layer) of the OSI Basic Reference Model, such as a router. Any interconnection among or between public, private, commercial, industrial, or governmental networks may also be defined as an internetwork.

In modern practice, the interconnected networks use the Internet Protocol. There are at least three variants of internetwork, depending on who administers and who participates in them:

Internetwork

• Intranet • Extranet • Internet

Intranets and extranets may or may not have connections to the Internet. If connected to the Internet, the intranet or extranet is normally protected from being accessed from the Internet without proper authorization. The Internet is not considered to be a part of the intranet or extranet, although it may serve as a portal for access to portions of an extranet.

An intranet is a set of interconnected networks, using the

Intranet

Internet Protocol and uses IP-based tools such as web browsers and ftp tools, that is under the control of a single administrative entity. That administrative entity closes the intranet to the rest of the world, and allows only specific users. Most commonly, an intranet is the internal network of a company or other enterprise.

An extranet is a network or internetwork that is limited in scope to a single organization or entity but which also has limited connections to the networks of one or more other usually, but not necessarily, trusted organizations or entities (e.g. a company's customers may be given access to some part of its intranet creating in this way an extranet, while at the same time the customers may not be considered 'trusted' from a security standpoint). Technically, an extranet may also be categorized as a CAN, MAN, WAN, or other type of network, although, by definition, an extranet cannot consist of a single LAN; it must have at least one connection with an external network.

Extranet

http://en.wikipedia.org/wiki/Internet_Protocol�

19 | P a g e


Internet

A specific internetwork, consisting of a worldwide interconnection of governmental, academic, public, and private networks based upon the Advanced Research Projects Agency Network (ARPANET) developed by ARPA of the U.S. Department of Defense – also home to the World Wide Web (WWW) and referred to as the 'Internet' with a capital 'I' to distinguish it from other generic internetworks.

Participants in the Internet, or their service providers, use IP Addresses obtained from address registries that control assignments. Service providers and large enterprises also exchange information on the reach ability of their address ranges through the Border Gateway Protocol (BGP).

Manufacturer’s Instruction Guide

Manufacturer’s Instruction Guide or simply manual may be a big help for you especially when you bought new materials or appliances at home. You don’t have to be professional to operate the material but by just following the procedure/steps listed on the manual, it may lighten your work. Manual usually covers all the functions and steps in configuring the material and/or on how to operate it. Manuals also provide steps in troubleshooting.

This is an example of what you may see on a Manufacturer’s Instruction Guide.

How to install a wired network adapter

To connect to a network, your computer needs a network adapter. Fortunately, most computer manufacturers know that connecting to the Internet or other computers is important to computer users, and they include a network adapter with your computer.

If you need to add a network adapter, first choose which method you want to use to install it. Most people prefer to use a USB (Universal Serial Bus) network adapter, because it's easy to install. If you have a portable computer, you might find a CardBus (also known as PCMCIA or PC Card) or CF network adapter better meets your needs. If you have a desktop computer with the proper amount of available space, you may also have the option of adding an internal network adapter.

The instructions you follow to install a network adapter depend on how you connect it.

How to determine if you have a network adapter

Many newer computers have a network adapter built in that you can use to connect to a wired network. If you want to install a wired network adapter and aren't sure whether your computer already has one, look for a network port on the back of the computer. Network ports resemble phone jacks, but they are slightly larger and have eight pins inside.

To see what kind of network adapters may already be installed in your computer.

1. Click the Start, and then click Control Panel

2. Under or pick a Control Panel icon, click Network Connections

3. Microsoft Windows XP displays your network adapters. If an adapter has a red X over it, it is disconnected. If the Network Connections window is blank, your computer doesn't have a network adapter

4. If you already have a network adapter, you are ready to configure your network.

How to install a wired USB network adapter

Once you have the adapter…

• If your USB network adapter came with software, insert the CD or floppy disk into your computer, and follow the manufacturer's instructions to install the software.

• Find an available USB port on your computer.

Note: If you need to move your computer to reach the USB ports, you should shut down Windows to avoid damaging your computer. If you can easily reach a USB port, you need not shut down your

computer.

• If you do not have an unused USB port, connect a USB hub to add additional ports. Then connect your USB network adapter to the unused USB port.

• Connect the network cable to the network adapter.

• Connect the other end of the network cable to your networking equipment.

• If you had to shut down your computer to get to the USB port, you can now turn on your computer. Windows detects and installs the new hardware, and then displays a notification informing you that the hardware has been successfully installed.

Today's computers have faster microprocessors, more memory and bigger hard drives. When you think about the differences between a Pentium 4 and 386, you have to conclude the improvement is astounding! But when error attacks your computer you have to do something for the computers to survive. Here are some of the common faults and problems that you may encounter:

1. Why computer becomes slow?

• You need more memory.

Don't overlook the obvious. Up until recently not having enough memory wasn't a problem. With the price of RAM becoming very affordable, most people were filling their computers with more than enough memory to do the job. If your computer is slow and it has lower capacity of RAM, you need to add more memory to speed it up.

• Spyware and viruses

34 | P a g e


Spyware. It is a software program that is intentionally installed on the computer by the user to monitor or spy on what the other users of the same computer is doing.

For this program to be effective, you have to keep up to date. By up to date, it means up to the minute.

Virus. A software program, macro or script that has been designed to infect, destroy, modify or cause other problems with computer or software program.

• Background programs

When you install new software on your computer, often times you install it to run in the background every time you start up. Most times you do this without knowing it. Look at the bottom right hand side of your screen.

If you see several icons there, you have extra programs running and stealing resources. Right click on these and see if you have the option of closing them. Many times, you can open the program and choose an option to keep these programs from starting automatically.

• Corrupted registry

Any changes you make to your computer effects and actually, it corrupts your registry even when you do something positive like remove spyware and you end up with a corrupted registry.

After months of corrupting your registry, it will become good. This will, in its early stages, cause your computer to slow down. In its advanced stages, it will freeze and crash and do more mysterious and troublesome things.

2. After I pressing the Power button...

• Check IDE ribbon cable is correctly connected to both Motherboard and CD-ROM • This may indicate a faulty CD-ROM Drive

PC is on but the CPU fan/fans do not spin

• Disconnect the power immediately to prevent damage to the CPU from overheating • Check fan power cables are correctly connected to the relevant power connector

(in most cases, a motherboard FAN connector or one of the PSU power connectors) • Disconnect the power and carefully spin the fan blades with a finger. If there is any

resistance to this movement, this may indicate a faulty fan unit

On boot up, the monitor shows corrupted display

• Check seating of CPU, RAM, Video card, sound card etc. If necessary, remove and refit these components

• Check the motherboard manual and perform a BIOS reset procedure

• This may indicate a faulty Motherboard or Video card

On boot up, display shows incorrect CPU type/speed

• Check the motherboard manual for the appropriate CPU jumper settings (where applicable)

• Check BIOS settings for CPU type (see Motherboard Manual) • Perform a BIOS reset procedure • Perform a BIOS update (with an updated BIOS, the Motherboard may support your

CPU) • This may indicate a faulty/old motherboard

On boot up, display shows incorrect RAM total

• Check correct seating of Memory Modules in slots • In cases of two or more modules, this may indicate a faulty module • This may indicate a faulty/old motherboard

On boot up, display shows - FDD/Keyboard/Mouse not found (or similar)

• Check correct connection of device described, In the case of the FDD, check its ribbon and power connections

• Check that the BIOS is configured correctly for the device described • This may indicate a fault with the described device or Motherboard

37 | P a g e


The monitor shows no picture

• Is the power light on? • Are the cables plugged in? • Check brightness and contrast settings. • Swap the monitor with another one, reboot the machine and see if it works. If the

computer works the monitor has probably gone bad. If it still fails to work, something in the CPU perhaps a video card has gone bad.

Computer displays limited colors.

• Check display options for the monitor usually under control panel under the display icon. Select at least 256 colors for standard display. If you had 16 color selected, this may be why your screen displays limited colors. Some programs such as FastCat require you to set display settings to 256 colors.

Signs of Video Display Troubles

If your screen is completely white or gray and you hear buzzing noises, this could indicate video card troubles. Before you panic, make sure all cables are secured from monitor to CPU. Try using another power cord for the monitor to see if this may be the problem.

If screen appears distorted around the edges and the color does not look right, you may have incorrect display adapters. Select Start, Settings, and Control Panel. Double click on System Icon and select Device Manager. You will see a listing of devices. Double click on Display adapters to view the type. If there is a yellow exclamation point next to device, there is a conflict. To view conflicts for a certain device, click on the device, select properties, and select the general tab. There should be a description of the device and why it is not working properly.

Printer Does Not Print.

• Are all cables connected and is the printer turned on? • Is the printer online? • Is there paper in the tray? • Is the printer an Inkjet/Deskjet or a Laserjet? • If it's an inkjet, is the ink cartridge out of ink. Remove cartridge, hold up to light or

gently shake it to see if it is empty. •

What is a Network?

A network consists of two or more computers that are linked in order to share resources (such as printers and CD-ROMs), exchange files, or allow electronic communications. The computers on a network may be linked through cables, telephone lines, radio waves, satellites, or infrared light beams.

The three basic types of networks include:

• Local Area Network (LAN) • Metropolitan Area Network (MAN)

• Wide Area Network (WAN)

Advantages of Installing a Network

• Speed. Networks provide a very rapid method for sharing and transferring files. Without a network, files are shared by copying them to floppy disks, then carrying or sending the disks from one computer to another. This method of transferring files (referred to as sneaker-net) is very time-consuming.

• Cost. Network cable versions of many popular software programs are available at considerable savings when compared to buying individually licensed copies. Besides monetary savings, sharing a program on a network allows for easier upgrading of the program. The changes have to be done only once, on the file server, instead of on all the individual workstations.

• Security. Files and programs on a network can be designated as "copy inhibit," so that you do not have to worry about illegal copying of programs. Also, passwords can be established for specific directories to restrict access to authorized users.

• Centralized Software Management. One of the greatest benefits of installing a network is the fact that all of the software can be loaded on one computer (the file server). This eliminates that need to spend time and energy installing updates and tracking files on independent computers throughout the building.

• Resource Sharing. Sharing resources is another area in which a network exceeds stand-alone computers. Most establishments cannot afford enough laser printers, fax machines, modems, scanners, and CD-ROM players for each computer. However, if these or similar peripherals are added to a network, they can be shared by many users.

• Electronic Mail. The presence of a network provides the hardware necessary to install an e-mail system. E-mail aids in personal and professional communication for all school personnel, and it facilitates the dissemination of general information to the entire school staff. Electronic mail on a LAN can enable students to communicate with teachers and peers at their own school. If the LAN is connected to the Internet, students can communicate with others throughout the world.

• Flexible Access. School networks allow students to access their files from computers throughout the school. Students can begin an assignment in their classroom, save part of it on a public access area of the network, and then go to the media center after school to finish their work. Students can also work cooperatively through the network.

• Workgroup Computing. Workgroup software (such as Microsoft BackOffice) allows many users to work on a document or project concurrently. For example, educators located at various schools within a county could simultaneously contribute their ideas about new curriculum standards to the same document and spreadsheets.

41 | P a g e


Disadvantages of Installing a School Network

• Expensive to Install. Although a network will generally save money over time, the initial costs of installation can be prohibitive. Cables, network cards, and software are expensive, and the installation may require the services of a technician.

• Requires Administrative Time. Proper maintenance of a network requires considerable time and expertise. Many schools have installed a network, only to find that they did not budget for the necessary administrative support.

• File Server May Fail. Although a file server is no more susceptible to failure than any other computer, when the files server "goes down," the entire network may come to a halt. When this happens, the entire school may lose access to necessary programs and files.

• Cables May Break. Some of the configurations are designed to minimize the inconvenience of a broken cable; with other configurations, one broken cable can stop the entire network.

What is a Protocol?

A protocol is a set of rules that governs the communications between computers on a network. These rules include guidelines that regulate the following characteristics of a network: access method, allowed physical topologies, types of cabling, and speed of data transfer.

The most common protocols are:

• Ethernet • Local Talk • Token Ring • FDDI • ATM

What is Networking Hardware?

Networking hardware includes all computers, peripherals, interface cards and other equipment needed to perform data-processing and communications within the network. CLICK on the terms below to learn more about those pieces of networking hardware.

42 | P a g e


This section provides information on the following components:

• File Servers • Workstations • Network Interface Cards • Switches • Repeaters • Bridges • Routers

File Servers

A file server stands at the heart of most networks. It is a very fast computer with a large amount of RAM and storage space, along with a fast network interface card. The network operating system software resides on this computer, along with any software applications and data files that need to be shared.

Workstations

All of the user computers connected to a network are called workstations. A typical workstation is a computer that is configured with a network interface card, networking software, and the appropriate cables. Workstations do not necessarily need floppy disk drives because files can be saved on the file server. Almost any computer can serve as a network workstation.

Network Interface Cards

The network interface card (NIC) provides the physical connection between the network and the computer workstation. Most NICs are internal, with the card fitting into an expansion slot inside the computer. Some computers, such as Mac Classics, use external boxes which are attached to a serial port or a SCSI port. Laptop computers can now be purchased with a network interface card built-in or with network cards that slip into a PCMCIA slot.

43 | P a g e


Network interface cards are a major factor in determining the speed and performance of a network. It is a good idea to use the fastest network card available for the type of workstation you are using.

Switch

A concentrator is a device that provides a central connection point for cables from workstations, servers, and peripherals. In a star topology, twisted-pair wire is run from each workstation to a central switch/hub. Most switches are active, that is they electrically amplify the signal as it moves from one device to another. Switches no longer broadcast network packets as hubs did in the past, they memorize addressing of computers and send the information to the correct location directly. Switches are:

• Usually configured with 8, 12, or 24 RJ-45 ports • Often used in a star or star-wired ring topology • Sold with specialized software for port management • Also called hubs • Usually installed in a standardized metal rack that also may store net modems,

bridges, or routers

Repeaters

Since a signal loses strength as it passes along a cable, it is often necessary to boost the signal with a device called a repeater. The repeater electrically amplifies the signal it receives and rebroadcasts it. Repeaters can be separate devices or they can be incorporated into a concentrator. They are used when the total length of your network cable exceeds the standards set for the type of cable being used.

Bridges

A bridge is a device that allows you to segment a large network into two smaller, more efficient networks. If you are adding to an older wiring scheme and want the new network to be up-to-date, a bridge can connect the two.

A bridge monitors the information traffic on both sides of the network so that it can pass packets of information to the correct location. Most bridges can "listen" to the network and automatically figure out the address of each computer on both sides of the bridge. The bridge can inspect each message and, if necessary, broadcast it on the other side of the network.

44 | P a g e


The bridge manages the traffic to maintain optimum performance on both sides of the network. You might say that the bridge is like a traffic cop at a busy intersection during rush hour. It keeps information flowing on both sides of the network, but it does not allow unnecessary traffic through. Bridges can be used to connect different types of cabling, or physical topologies. They must, however, be used between networks with the same protocol.

Routers

A router translates information from one network to another; it is similar to a super intelligent bridge. Routers select the best path to route a message, based on the destination address and origin. The router can direct traffic to prevent head-on collisions, and is smart enough to know when to direct traffic along back roads and shortcuts.

If you have a school LAN that you want to connect to the Internet, you will need to purchase a router. In this case, the router serves as the translator between the information on your LAN and the Internet. It also determines the best route to send the data over the Internet. Routers can:

• Direct signal traffic efficiently • Route messages between any two protocols • Route messages between linear bus, star, and star-wired ring topologies • Route messages across fiber optic, coaxial, and twisted-pair cabling

What is Network Cabling?

Cable is the medium through which information usually moves from one network device to another. There are several types of cable which are commonly used with LANs. In some cases, a network will utilize only one type of cable, other networks will use a variety of cable types. The type of cable chosen for a network is related to the network's topology, protocol, and size. Understanding the characteristics of different types of cable and how they relate to other aspects of a network is necessary for the development of a successful network.

The following sections discuss the types of cables used in networks and other related topics.

• Unshielded Twisted Pair (UTP) Cable • Shielded Twisted Pair (STP) Cable • Coaxial Cable • Fiber Optic Cable • Wireless LANs

45 | P a g e


Unshielded Twisted Pair (UTP) Cable

Twisted pair cabling comes in two varieties: shielded and unshielded. Unshielded twisted pair (UTP) is the most popular and is generally the best option for school networks (See fig. 1).

Unshielded twisted pair

Categories of Unshielded Twisted Pair

Type Use

Category 1 Voice Only (Telephone Wire)

Category 2 Data to 4 Mbps (Local Talk)

Category 3 Data to 10 Mbps (Ethernet)

Category 4 Data to 20 Mbps (16 Mbps Token Ring)

Category 5 Data to 100 Mbps (Fast Ethernet)

Unshielded Twisted Pair Connector

The standard connector for unshielded twisted pair cabling is an RJ-45 connector. This is a plastic connector that looks like a large telephone-style connector. A slot allows the RJ-45 to be inserted only one way. RJ stands for Registered Jack, implying that the connector follows a standard borrowed from the telephone industry. This standard designates which wire goes with each pin inside the connector.

46 | P a g e


RJ-45 connector

Shielded Twisted Pair (STP) Cable

A disadvantage of UTP is that it may be susceptible to radio and electrical frequency interference. Shielded twisted pair (STP) is suitable for environments with electrical interference; however, the extra shielding can make the cables quite bulky. Shielded twisted pair is often used on networks using Token Ring topology.

Coaxial Cable

Coaxial cabling has a single copper conductor at its center. A plastic layer provides insulation between the center conductor and a braided metal shield. The metal shield helps to block any outside interference from fluorescent lights, motors, and other computers.

Coaxial cable

Although coaxial cabling is difficult to install, it is highly resistant to signal interference. In addition, it can support greater cable lengths between network devices than twisted pair cable. The two types of coaxial cabling are thick coaxial and thin coaxial.

Wireless LANs

Not all networks are connected with cabling; some networks are wireless. Wireless LANs use high frequency radio signals, infrared light beams, or lasers to communicate between the workstations and the file server or hubs. Each workstation and file server on a wireless network has some sort of transceiver/antenna to send and receive the data. Information is relayed between transceivers as if they were physically connected. For longer distance, wireless communications can also take place through cellular telephone technology, microwave transmission, or by satellite.

47 | P a g e


Wireless networks are great for allowing laptop computers or remote computers to connect to the LAN. Wireless networks are also beneficial in older buildings where it may be difficult or impossible to install cables.

What is a Network Operating System?

Unlike operating systems, such as DOS and Windows, that are designed for single users to control one computer, network operating systems (NOS) coordinate the activities of multiple computers across a network. The network operating system acts as a director to keep the network running smoothly.

The two major types of network operating systems are:

• Peer-to-Peer • Client/Server

Peer-to-Peer

Peer-to-peer network operating systems allow users to share resources and files located on their computers and to access shared resources found on other computers. However, they do not have a file server or a centralized management source. In a peer-to-peer network, all computers are considered equal; they all have the same abilities to use the resources available on the network. Peer-to-peer networks are designed primarily for small to medium local area networks. AppleShare and Windows for Workgroups are examples of programs that can function as peer-to-peer network operating systems.

Peer-to-peer network

Advantages of a peer-to-peer network:

• Less initial expense - No need for a dedicated server. • Setup - An operating system (such as Windows XP) already in place may only need

to be reconfigured for peer-to-peer operations.

48 | P a g e


Disadvantages of a peer-to-peer network:

• Decentralized - No central repository for files and applications. • Security - Does not provide the security available on a client/server network.

Client/Server

Client/server network operating systems allow the network to centralize functions and applications in one or more dedicated file servers. The file servers become the heart of the system, providing access to resources and providing security. Individual workstations (clients) have access to the resources available on the file servers. The network operating system provides the mechanism to integrate all the components of the network and allow multiple users to simultaneously share the same resources irrespective of physical location. Novell Netware and Windows 2000 Server are examples of client/server network operating systems.

Client/server network

Advantages of a client/server network:

• Centralized - Resources and data security are controlled through the server. • Scalability - Any or all elements can be replaced individually as needs increase. • Flexibility - New technology can be easily integrated into system. • Interoperability - All components (client/network/server) work together. • Accessibility - Server can be accessed remotely and across multiple platforms.

Disadvantages of a client/server network:

• Expense - Requires initial investment in dedicated server. • Maintenance - Large networks will require a staff to ensure efficient operation. • Dependence - When server goes down, operations will cease across the network.

49 | P a g e


UTP Cable

A UTP cable (category 5) is one of the most popular LAN cables. This cable consists of 4 twisted pairs of metal wires (that means there are 8 wires in the cable). Adding RJ45 connectors at both ends of the UTP cable it becomes a LAN cable they usually use.

Preparation

You need a UTP Cable, Crimping Tool, RJ45, and Cutter

Making Cable

Follow the steps below.

50 | P a g e


1. Remove the outmost vinyl shield for 12mm at one end of the cable (we call this side A-side).

2. Arrange the metal wires in parallel (refer the each section's wire arrangement table). Don't remove the shield of each metal line.

3. Insert the metal wires into RJ45 connector on keeping the metal wire arrangement. 4. Set the RJ45 connector (with the cable) on the pliers, and squeeze it tightly. 5. Make the other side of the cable (we call this side B-side) in the same way. 6. After you made it, you don't need to take care of the direction of the cable. (Any

cable in this page is directionless --- that means you can set either end of the cable to either device.)

How to see the wire arrangement

Take the UTP cable with your left hand and a RJ45 connector with your right hand. Hold the RJ45 connector in the way you can see the contact metal face of the RJ45 connector.

The tables below are for the case where the UTP cable consists of green/green-white, orange/orange-white, blue/blue-white, brown/brown-white twisted pairs.

10 Base T / 100 Base T Straight

10BaseT and 100BaseT are most common mode of LAN. You can use UTP category-5 cable for both mode. (You can use UTP category-3 cable for 10BaseT, in which there are only 3 wires inside the cable.)

A straight cable is used to connect a computer to a hub. You can use it to connect 2

51 | P a g e


hubs in the case one of the hubs has an uplink port (and you use normal port on the other hub).

10 Base T / 100 Base T Cross

A cross cable for 10BaseT and 100BaseT is used to connect 2 computers directly (with ONLY the UTP cable). It is also used when you connect 2 hubs with a normal port on both hubs. (In other words, the cross cable is used relatively in a rare case.)

To create a peer network, you must have the following components:

• A network interface or Local Area Network (LAN) adapter for each computer. The same manufacturer and model of network card is preferred.

• Cabling that is supported by the network cards.

• Windows 98 drivers for the network cards.

• A common network protocol.

• A unique computer name for each computer.

To create a peer network, follow these steps for each computer connected to the network:

1. Shut down the computer and install the network card and appropriate cabling for each computer.

53 | P a g e


NOTE: For information about how to configure your network adapters and physically connect your computers, consult the documentation included with your network adapters or contact the manufacturer(s) of your network adapters.

2. Start Windows and install the network drivers. Windows may detect your network card and install the drivers when you start the computer. If the network card drivers are not included with Windows, follow the manufacturer's instructions about how to install the network drivers.

.

3. Choose a client and a common protocol for each computer. To do this, follow these steps:

a. Click Start, point to Settings, click Control Panel, and then double-click Network.

b. Click Add, click Client, and then click Add.

c. In the Manufacturers box, click the appropriate manufacturer, click the appropriate client in the Network Clients box, and then click OK.

d. Click Add, click Protocol, and then click Add.

e. In the Manufacturers box, click the appropriate manufacturer, click the appropriate protocol in the Network Protocol box, and then click OK.

.

4. Configure a peer server. Each computer that is configured for File and Printer Sharing can act as a server. To configure a computer for File and Printer Sharing, use the following steps:


b. Click File and Print Sharing, click one or both options to share files and printers, click OK, and then click OK again.

54 | P a g e


c. Click Yes when you are prompted to restart your computer.

.

5. Give each computer a unique computer name. To do this, use the following steps:


b. On the Identification tab, type a unique name in the Computer name

c.

box.

Click OK, and then click Yes when you are prompted to restart your computer.

NOTE: The computer name must be unique for each computer on the network and should be no more than 15 characters in length. In small networks, the workgroup name should be the same for each computer so that all computers are visible in the same workgroup when browsing. You should not use spaces or the following characters in computer and workgroup names:

Windows XP Networking

As in previous versions of Windows, Windows XP provides a wizard for network connection setup. Wizards break down a task into individual steps and guide the user through the steps one at a time.

The Windows XP New Connection Wizard supports two basic types of Internet connections, dialup and broadband.

To access the network connection setup wizard in Windows XP, navigate through the Start menu to the Connect To and Show all connections options as shown below.

http://compnetworking.about.com/library/glossary/bldef-dialup.htm�

http://compnetworking.about.com/library/glossary/bldef-broadband.htm�

55 | P a g e


The same feature is also accessible via the Network Connections icon in Control Panel.

Choosing either of the above options causes a new window to appear on the desktop as shown below. On the right, this window displays icons for any pre-existing connections. The Create a new connection option on the left allows new connections to be set up.

Types of Windows XP Network Connection Setup

56 | P a g e


Clicking the Create a new connection option from the Network Connections dialog activates the wizard as shown below.

Clicking Next presents the user with three main choices for Internet and private network setup as shown below.

The Connect to the Internet option supports several types of Internet connection setup. This option allows the user to choose from a list of ISPs, use a setup CD-ROM provided by their ISP, or set up a connection manually.

Connect to the network at my workplace supports client-side set up of both dialup remote access and VPN services.

The Set up an advanced connection option supports serial, parallel and infrared port networking setups. This option also allows the user to enable certain types of incoming network connections.

http://compnetworking.about.com/library/glossary/bldef-isp.htm�

57 | P a g e


Setting up an Internet Connection

The Getting Ready page presents three choices as shown below:

The Choose from a list of Internet Service Providers option gives instructions for setting up an account with an ISP, then making the Internet connection through that new account.

The Set up my connection manually option sets up connections for accounts that have already been opened with an ISP (username and password are ready for use).

The Use the CD I got from an ISP option should be used when possessing an installation CD-ROM from one of the service providers.

By default the first option Get online with MSN (Microsoft Network) is selected. To set up a new connection to MSN, click Finish. To set up a new connection to various other ISPs, change the radio button selection to the second option and then click Finish.

MSN Internet Connection Setup

After choosing MSN and clicking Finish, the Windows XP network connection wizard closes and a new window opens as shown below.

http://compnetworking.about.com/library/glossary/bldef-isp.htm�

58 | P a g e


This window leads to the MSN Explorer Wizard. Answering Yes to this question creates a key in the Windows Registry that allows access to MSN email from the Windows XP Start Menu. Answering No to this question skips that step. After answering either Yes or No, the MSN wizard launches automatically.

The MSN wizard sets up an MSN account and dial-up Internet connection but require a working phone line connected to a working modem.

Other ISP Internet Connection Setup

After choosing an alternate ISP and clicking Finish, the Windows XP network connection wizard closes and a new Windows Explorer window opens as shown below.

The first shortcut launches the MSN window shown above. The second shortcut launches a new Internet Connection Wizard. This wizard dials a public phone number to obtain a list of ISP referrals from Microsoft. Obviously, this wizard will provide a limited list of service providers and not necessarily the best ones for each individual's needs.

These shortcuts, installed in C:\Program Files\Online Services, can be accessed at any time from Windows Explorer. It is not necessary to navigate through the Windows XP network connection wizard to execute them.

This wizard assumes an account has been opened previously. Manual connections require the username (account name) and password from a working ISP service. Dial-up connections also require a telephone number; broadband connections do not.

The next step presents three options for creating a manual connection.

The Connect using a dial-up modem option works for phone line Internet services (either traditional dial-up or ISDN).

The Connect using a broadband connection that requires a user name and password option works for DSL or cable modem Internet services that use PPPoE.

The Connect using a broadband connection that is always on option works for true "always on" DSL or cable modem services (those that do not require a username/password) as specified in their service agreement.

Microsoft added this option for informational purposes only. Service providers normally create their setup CDs to include all of the necessary setup data for an operating system in a self-contained package. Therefore, clicking Finish has no effect other than to exit the wizard.

You have learned from Information Sheet #2.2.6 how to configure a Peer-to-Peer network and XP connection with Internet. Now to check if the LAN connection is really working, you must try to share your resources and accessed shared resources of other computer. Make sure that you follow the standard operating procedures in configuring network to achieve successful operation.

Sharing Resources and Accessing Shared Resources

1. Open My Computer, double-click the C: drive, and create a new folder on the C: drive. Name it Shared. Right-click the Shared folder and select Properties.

65 | P a g e


2. In the Shared Properties dialog box, select the Sharing tab. Notice that the. Select the Share This Folder button. Type the Share Name. Click Apply and the computer you are linked to should be able to view your Shared folder. 3. Right-click My Network Places, which should be located on your desktop. Select

Properties. Right-click your connection (look for a name like Local Area Connection) and again select Properties. In your Local Area Connection Properties dialog box, select File and Print Sharing for Microsoft Networks and click OK. If you don’t see an option for File and Print Sharing, click Install and select a service and then click Add. Now select the File and Print Sharing option.

4. Open My Network Places- double-click the icon- and select the Entire Network option under Other Places at the left of the window. In the main (right-hand) pane, you should see one or more options. Double-click the Microsoft Windows Network icon. 5. You’re now at the main network screen, where you should see what’s called a workgroup. A workgroup is a basic group of computers connected to the same Ethernet

Local Disk (C:\PC 1)

network. Double-click the workgroup to see all the computers connected to your Ethernet network.

At this point, you can access any of the other computers and see what folders they have shared. If you don’t see any computer but your own, just wait a few minutes and refresh your screen. Then it’s time to troubleshoot the network problems. In a network, other peripherals such as printer and faxes could also be shared. You could use one computer in a network of 10 computers. Click the Print command, when the dialog box appears click Find Printer. Then click Browse. Find the location of the printer you will use.

If you don’t have any printer installed in your computer, here’s the step on how: TO ADD A PRINTER: 1. Click Start button, then point to Printer and Faxes.

67 | P a g e


2. A window will be displayed showing Click Add a Printer on the Taskpane (if there are

printers already installed).

3. To continue, click Next.

4. Select what kind of printer you are going to connect, Local printer or Network printer.

68 | P a g e


5. Select Printer port.

6. Below Manufacturer, Click on the name of the printer's manufacturer. Manufacturers are listed in alphabetical order and you may have to click on the little down arrow until the manufacturer's name appears in the list.

Below Model, Click on the model of the printer you will be using. Model names are listed in alphabetical order and you may need to click on the little down arrow until the model name appears in the list.

Note: You can often find the manufacturer and model names by looking on the printer itself.

7. Click the Next button. Windows will check to see if it has the software necessary to communicate with the printer (the software your computer needs to communicate with devices like printers, monitors, and disk drives is known as a driver). If so, it will install the software automatically.

Note: If you receive a message saying that Windows was unable to locate the necessary files, you will need to get the necessary software before continuing. Most often, the printer manufacturer's Web site will have a section called

Drivers, from which you can download the software necessary to use their products. If you

69 | P a g e


are unable to locate the software on the manufacturer's Web site, inquire within your department to see if someone is in possession of a software installation disk for the printer. Once you have obtained the necessary software, click here for instructions on installing a driver.

• Assign your Printer name. Click Next. If you want to test page, click Yes. Click Next.

9. Then Finish. Right-click on the printer you installed. Click Set as Default.
