TOPOLIGI network

Understanding , a variety of computer network topology ~ We have had many users device topology network computers, particularly in offices and so on. Its use is helping to facilitate the access of the data to the server simultaneously. This is the main reason for the formation of the computer network topology. And along with the development of the network is also developing a variety of network topologies that computer.

DEFINITION OF COMPUTER NETWORK TYPE Topology

Understanding the network topology is a technique to connect one computer to another computer that assemble into a network, where the network topology is based on the use of cost, speed of data access, the size and the level of connectivity that will affect the quality and efiensi a network. There are various kinds of network topology many computers in use today include Bus Topology, Ring Topology, Star Topology, Mesh Topology, Linear Topology, each of these topology types have their own advantages and the minuts

Various computer network topology

This type of bus topology uses a single cable, the entire computer is directly interconnected using only one cable. Cable that connects this network is using coaxial cables and attached to the T-Connector.

1 .Topology Bus

 To maximize the use of this network should use the Fiber Optic cable for stability of resistance that can transmit the data better.

Excess Bus Topology: 1. Easy to be developed 2. Does not require a lot of cable 3. Save the cost of installation of a

bus topology Weaknesses:   Unstable, if one computer is

interrupted then the network will be disrupted 

Error detection rate is very small   Difficult to find interference on

the network   Required for remote repeater 

2.Topologi RingThis type of ring topology, all computers are connected together to form a circle (ring) covered and assisted by token, token contains information derived from the source computer will check whether the information is used by the point in question,

if there is then the token will provide data that requested by the network point and headed to the next point. 

all of the computers will receive any signal flowing information, the information will be accepted if it is in conformity with the address, and the signal will be ignored if the information is not the address itself.

In other words, this process will continue until the data signal is received at the destination. Advantages: 

1. Do not use a lot of wiring 2.Installation of a low level of complexity 

3. Easy installation 4. Not going to happen hit the data 

5. Easily designed Disadvantages: 1. sensitive network error 2. Difficult to develop 3. If one point disrupted the entire network

of data communications can be disrupted

On the type of star topology, each computer is directly connected using a hub, where the function of this Hub is a traffic control all computers connected.Because it uses the process of sending and receiving information directly is what causes the installation costs are also high. 

3. Star Topology

Advantages: 1. Error detection is performed 

2. Change the station easy to do and does not interfere with other networks 

3. Easily control 4. High security level 5. The most flexibleDisadvantages:  Using a lot of wiring There is a possibility of data collision

will occur which can result in slow network 

 Network is dependent upon the central terminal 

High network costs If the computer is the center point of

the interference disrupted the entire network

This tree topology is a result of the development of the star topology and bus topology consists of a collection of star topology and bus topology associated with

4. Topology Tree

1. Tree topology is usually referred to as the network topology and used multilevel interconnection between central. 

topology of this tree has the same strengths and weaknesses with a star topology, among others: Pros: 1. Error detection is performed 2 . Changes in the shape of a group is easy to do and does not interfere with other networks 

At this network has several levels with a specified node hierarchy, the picture is the higher the position, the higher its hierarchy. Each node that has a high position who has a node can set a low position. Data sent from the central node and then move towards a low node and leading to higher node first. 

3.Easily control Disadvantages:  Using a lot of wiring  Frequent collisions  If the node is higher then the

damaged lower node will be interrupted too 

How it works slow

Mesh topology is a series of interconnected networks where each device absolutely computers will be connected directly to any point other devices. Each point has a point that the computer will be ready to communicate directly with other computer devices point into the goal. 

5. Topologi Mesh

Advantages: 1. Dynamic point in repairing any damage to

computer networks 2. The data is sent directly to the destination

without having to go through another computer 

3. The data faster data transmission process 

4. If there is damage to one of the computers will not interfere with other computer Disadvantages: 

The cost to set it up so big. Need a lot of cable It should be a lot of I / O ports, each computer is required n-1 I / O port and as many as n (n-1) / 2 connections. For example, there are 4 computers will require a cable connection 4 (4-1) / 2 = 6 cable and requires 4-1 = 3 ports. 

 Difficult and complicated installation process

This is an extension of the topology of a bus topology in which the main cables should be connected to a computer each point using the T-connector. The topology of this type is a simple type using RG-58 cable. 

6. Linear topology

Advantages: 1. Simple network 2. Save the cable 3. Easily expandable Disadvantages: 1. Detection of very small mistakes 2. Safety not guaranteed 3. High data traffic 4. The transfer speed depends on the

number of users, speed down if the number of users increases That article understanding of  a variety of computer network topology , hopefully can provide benefits, greetings
