| RING |
|
 |
|
| A cable forms a closed loop (ring) with all computers and devices arranged along the ring | |
|
Data transmitted on a ring network travels from device to
device around 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 Topology |
Disadvantages of Ring Topology |
|
All computers have equals access to the resources in the
network |
The network will be malfunctioned if the device (pc/devices)
breaks down |
|
The users of token passing enable all devices in a ring
topology to share the network resources fairly |
A ring network can span larger distance that a bus network but
it more difficult counselling |
|
Cable faults are easily located, making troubleshooting
easier. |
Data packets must pass through every computer therefore, that
makes it slower |
