Types of Computer Network Topology

Computer Network Topology 

1. Understanding Topology BUS
Bus Topology is a topology widely used in the cable uses sepaksi mushroomed. By using T-Connector (with a 50 ohm terminator at the end of the network), then the computer or other network devices can be easily connected to each other.

Excess 

• Save cables
•  Layout simple cable 
• easily developed

Shortage

• Detection and isolation of faults are very minor 
• Traffic density 
• If one client is broken, then the network can not function. 
• Required repeater for long distance

2. Understanding Topology RING
Token-ring method (often called the ring anyway) is how the computer so that the ring-shaped (circular). Each node has the same degree. The network will be referred to as a loop, the data is sent in each node and any information received nodes examined whether the data address for him or not.

Benefit 

• Save Cables

Costs 

• sensitive errors 
• Develop a network of more rigid

3. Understanding Topology STAR
Centralized control, all links must pass through the center channel all these data node or client of choice. Stasium called primary central node or server and the other is called secondary station or client server. Once the network connection initiated by the server, each client server sometimes can use a network connection without waiting for orders from the server.

Advantages: 

• most flexible 
• Installation / changing station is very easy and does not interfere with other parts of the network 
• centralized control 
• Ease of detection and fault isolation / damage 
• Ease of network management

Disadvantages: 

• cable loss 
• Need special handling
•  Centralized control (HUB) so critical element 

4. Understanding Topology Tree
Topology Tree (Tree) is a combination of characteristics between star topology and bus topology. This topology consists of a collection of star topology are connected in a bus topology as the backbone. Computers connected to the hub, while the other hub connecting the spine or backbone path. 

Advantages:

• Can the formation of a group that is required at all times. For example, companies can form a group consisting of terminal bookkeeping, as well as the other groups formed for the sales terminal.

Disadvantages:

• If the node is higher then not working, then other groups that are below it eventually becomes ineffective. The workings of a tree network is relatively slow. 

Advantages:

• Relationship dedicated links to ensure the data is sent directly to the destination computer without having to go through other computers so that they can more quickly because of the link is used exclusively for communicating with the destination computer only (not used beramai-ramai/sharing). 
• Robust properties, ie the event of disruption in the connection of computer A with computer B because of damage to the cable connections (links) between A and B, then the interference will not affect A computer connection with other computers. 
• Privacy and security in mesh topology more secure, because the communication that occurs between the two computers will not be accessible by other computers.
•  Facilitate the process of identifying the problems in the event of damage to connections between computers.

Disadvantages:

• Requires a lot of cable and port I / O. more and more computers in the mesh topology is needed more and more cable links and port I / O (see calculation formula needs wiring and Port). 
• It is at once also indicate that the topology of this type * Because each computer must be connected directly to another computer then the installation and configuration becomes more difficult. 
• The number of wires used also suggests the need for space that allows in the room where the computers are located. 

5. Topology Peer-to-peer Network
 
Peer meaning colleagues. Peer-to-peer network is a computer network consisting of multiple computers (usually no more than 10 computers with printers 1-2). 

In the preferred system of this network is the use of the program, data and printers together. Users can use the computer named Dona program installed on the computer Dino, and they both can print to the same printer at the same time. Network system can also be used at home.  

Computer users who have computers 'old', eg AT, and want memberli new computer, say Pentium II, no need to throw away old computers.  

He simply install a second network card in the computer and then connected by special cables used for network systems. Compared with the three methods, the system is much simpler network that is easier to learn and use.
