2) RING NETWORK
DIAGRAM OF RING NETWORK:
|
DEFINITION/PHYSICAL TOPOLOGY OF RING NETWORK |
On a ring network, a cable forms a closed loop (ring) with all computers and devices arranged along the ring. |
LOGICAL TOPOLOGY OF RING NETWORK/
HOW DATA TRANSMIT
|
Data transmitted on a ring network travels from device to device around the entire ring, in one direction (clockwise or counterclockwise) until it reach its destination by using token.
Token passing is one method for sending data around a ring. Each device takes a turn sending and receiving information through the use of a token.
Token is a special series of bit that functions like a ticket.
|
ADVANTAGES OF RING NETWORK
|
1. All computers have equals access to the resources in the network. 2. The uses of token passing enables all devices in a ring topology to share the network resources fairly.
3. Cable faults are easily located, making troubleshooting easier.
4. Data packet are flowing in one direction at high speed around the ring.
5. The transmission of data is relatively simple as packets travel in one direction only.
|
DISADVANTAGES OF RING NETWORK
|
1. The network will be malfunctioned if the device (pc/device) or cable break down. 2. A ring network can span a larger distance than a bus network, but it is more difficult to install.
3. Data packets must pass through every computer therefore, this makes it slower.
