NETWORK TOPOLOGY
DEFINITION/ PHYSICAL TOPOLOGY OF RING NETWORK
A cable forms a closed loop (ring) with all computers and devices arranged along the ring.
LOGICAL TOPOLOGY/ 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 sendng and receiving information through the use of a token.
- Token is a special series of bit that functions like a ticket.
ADVANTAGES :
- All computers have equals access to the resources in the network.
- Cable faults are easily located, making troubleshooting easier.
- Data packet are flowing in one direction at high speed around the ring,
DISADVANTAGES :
- The network will be malfunctioned if the device (pc/device) or cable break down.
- A ring network can span larger distance than a bus network, but it is more difficult to install.
- Data packets must pass through every computer therefore, this makes it slower.
