TODAYS TOPICS HIGHLIGHTS

Virtual networking Wired networking Wireless networking And other small topics

WHAT IS VIRTUAL MACHINE?

Here Virtual machine means a software which provide us a platform to create as many virtual computers depending upon system configuration of our computer.

Mostly used virtual machine 1.Oracle VM Virtual box {freeware} 2.VM Ware {pay money}

ADVANTAGES OF VIRTUAL MACHINE

Create a independent virtual computer Different OS can be installed we can manage RAM, HDD, Processor, ODD, pendrive etc If virtual computer is damaged then we can create new

virtual computer, it does not harm any of our system files and our document.

By using virtual machine many people have been able to be familiar with different type of OS. Eg linux, windows, MAC, Sun Solaris etc.

New software can be tried before use in real machine. Every hacking, Networking, can be learned by creating

virtual computers.

WHY SHOULD WE USE VIRTUAL MACHINE? We should use virtual machine in order

to practice and to learn. So that we don’t make any mistake on

our real machine. To try new software and new ideas.

POWER ISO AND ISO IMAGE

Power iso is a software which help us to create and extract zip type of file which is also called image. it help us to create duplicates of the films in cd, or software from a cd or to zip any file. it can create different extension images such

as 1. .iso 2. .daa 3 .bin

ISO IMAGE

We can create iso image for using virtual machine because in virtual machine we can open iso image as an dvd-rom.

WHAT IS NETWORKING?

Networking is connection of two or more computers with wire or wireless connection to share it’s available resources.

Such as Harddisk, cd-rom, printer, software and

files etc Important note- we don’t need internet

to do networking.

ADVANTAGES OF NETWORKING

Helps us to share available resources such as printer, scanner, cd-rom, harddisk

Help us in communication such as calling, messaging, etc

Help us to solve problem staying in same place. E.g remote desktop connection

Makes our daily work easier. RIS(Remote Installation Service) Internet sharing

DISADVANTAGES OF NETWORKING

If one computer is infected with viruses then whole computer will be infected by viruses.

If switch is not working then whole network system does not work.

etc

TYPES OF NETWORKING

LAN MAN WAN PAIR TO PAIR NETWORKING SERVER CLIENT NETWORKING

LAN(LOCAL AREA NETWORKING)

The networking done in small area. i.e within room or from one room to

another or within a building E.g school, colleges, offices, institute And today we will do LAN networking

with wire and wireless i.e wifi.

SIMPLE LAN NETWORK WITH SWITCH ONLY

COMPLEX LAN WITH ROUTER AND WIFI

MAN(METROPOLITAN AREA NETWORK) . A network connecting computers over

a large geographical area, such as a city or school district.

MAN

WAN(WIDE AREA NETWORKING)

The networking in wide area. E.g internet

WAN

NETWORKING CAN BE DONE BY DIFFERENT WAYS

1. WITH COMPUTER NAME 2.WITH IP ADDRESS TYPES CLASS A CLASS B CLASS C

TODAY WE WILL DO LAN NETWORKING WITH COMPUTER NAMES

Because we are going to do networking in small area i.e in a hall. But before that we will practice networking in virtual machine.

After that we will do networking with wires and wireless devices.

NETWORKING WITH COMPUTER NAMES It is the easiest way of networking

because here we don’t have to know what is static and dynamic IP address is.

But in reality, while doing networking, computer name uses dynamic ip address.

Dynamic ip address means ip address changes frequently.

It is used widely

NETWORING WITH COMPUTER NAMES RULES Some rules must be followed in order to

make a networking of the computers 1.Computer name must be different but

workgroup must be same. 2.Firewall must be off 3.Guest must be enabled 4. Guest must be given access in

network

1.COMPUTER NAME MUST BE DIFFERENT AND WORKGROUP MUST BE SAME

Right click on my computer. Properties Computer name

Change Give the computer name and

workgroup. Restart your computer.

2.FIREWALL MUST BE OFF

Start control panel firewall off Or Win+r firewall.cpl off

3.GUEST MUST BE ENABLED

Right click on my computer Manage local users and groups

users double click on guest remove tick from account is disabled.

Or Win+r lusrmgr.msc users

double click on guest remove tick from account is disabled.

4.GUEST MUST BE GIVEN ACCESS IN NETWORK

Start control panel administrative tools local security policy local policy user right assignment double click on deny access to this computer from network select guest remove ok

Or Win+r secpol.msc local policy user

right assignment double click on deny access to this computer from network select guest remove ok

THE THINGS WE CAN DO AFTER WE ARE IN NETWORK

1.File sharing, drive sharing, printer N scanner sharing

2. Netmeeting – help us in chatting, free calls and desktop sharing.

3.Remote desktop connection – help us to control our friend computer.

4.shutting down network computers.

1.FILE SHARING, DRIVE SHARING, PRINTER N SCANNER SHARING

Folder sharing Create a folder and give name right

click on folder properties sharing tick on share this folder on network and allow network users to change my file apply ok

Same method for cd-rom and drive sharing.

2. NETMEETING – HELP US IN CHATTING, FREE CALLS AND DESKTOP SHARING.

Start run conf fill all the empty area as needed next next next next next next next next finish

Right click on my computer properties remote tick on allow users to connect remotely to this computer apply ok

Start all programs accessories communication remote desktop connection

Type computer name and click connect

4.SHUTTING DOWN NETWORK COMPUTERS.

Start control panel administrative tools local security policy local policy user right assignment double click on force shutdown from remote computer add users or groups type everyone check names ok apply ok

Start run cmd type shutdown –I add type computer name to shutdown ok add comment ok
