COMPUTER NETWORK TOPOLOGY

Topology is a way of connecting one computer with another computer so that form the network. The current way is a widely used bus, token-ring, star and peer-to-peer network. Each of these technologies has distinctive features, with its own strengths and weaknesses.

 

 

1. The BUS Topology
 
Advantage
• Cost-efficient cable
• Simple wiring Layouts
• Easily developed

Losses

• hard to do detection and isolation of the fault.
• The density of traffic, because the model is the data line 2 direction.
• When one client is broken, so the network will be disrupted.
• Repeater Needed to remotely

2. Token RING Topology

Method token-ring (often called the ring only) is a way of connecting computers so that the ring-shaped (circle). Each node has the same level. The network will be referred to as a loop, the data submitted kesetiap node and any information received the knot checked the address whether data was for him or not

Advantage

• Cost-Efficient Cable
• Direct data Line, so its data traffic better.

Losses

• Sensitive errors
• If the cable broke in the middle of the network, the network is not functioning.
• The development of a network of more rigid

3. The STAR Topology

Centralized control, all links must pass through the center channel that data all node or client that he has chosen. Central node called stasium primary or server and other is called secondary station or client server. After the network connection is initiated by the server then any client server at any time can use the network connection without waiting for orders from the server.

Advantage

• The most flexible
• Installation/change station is very easy and does not interfere with other network section
• Centralized Control
• Ease of detection and isolation of the fault/damage
• Network management Kemudahaan

Losses

• Cable Wastes
• Need special handling
• Centralized Control (HUB) so critical elements

4. Topology of Peer-to-peer Network

Peer means co-workers. Peer-to-peer network is a computer network that consists of 2 computers. In this network the preferred system is the use of the program, data and printer together. Computer user name Dona can you use programs that are installed in the your computer the Dino, and they both can print to the same printer at the same time. This network system can also be used at home. Computer users who have computers ' antiquated ', for example AT i486, and want to purchase new computers, such as Intel Core 2 Duo, no need to throw away the computer ever. He simply plug the netword card in both his computer and then connected with a special cable that is used for network system. Compared with the third way above, this network system is simpler and thus more easily dipejari and wear.
