BUS NEYWORK TOPOLOGY
- a bus network
consists of a single central cable(backbone/trunk) to which all
computers and other devices connect(node)
LOGICAL TOPOLOGY OF BUS NETWORK
- In a bus network it transmit data, instructions and
information asa series of signal but only the intended recipient will
accept the signal and the rest will ignore.
ADVANTAGES OF BUS TOPOLOGY
|
DISADVANTAGES OF BUS TOPOLOGY
|
Failure of one device usually does not affect the rest of the bus
network
|
The network will be malfunctioned if the single central cable
break down
|
Inexpensive and easy to install
|
It is difficult to identify the problem if the entire network shut
down
|
|
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
- 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 devices takes a turn sending and receiving information through the use of a token
- Token is a special series of bits that functions like a ticket
ADVANTAGES OF RING TOPOLOGY
|
DISADVANTAGES OF RING TOPOLOGY
|
All the computers have equal access to the resources in the
network
|
The network will be malfunctioned if the device (pc/device) or
cable break down
|
Cable faults are easily located, making troubleshooting easier
|
A ring network can span a larger distance than a bus network but
it is difficult to install
|
|
STAR NETWORK
- all the computers and
other devices on the network connect to a central device
(hub/switch), thus forming a star
LOGICAL TOPOLOGY OF STAR NETWORK
- In a star network data instruction and informations transfer from one node to another node passes through hub/switch
ADVANTAGES OF STAR NETWORK
|
DISADVANTAGES OF STAR NETWORK
|
If one device (pc/printer) fail only that device is affected
|
The network will be malfunctioned if the single hub/switch break
down
|
Easy to troubleshoot and isolate problem
|
Requires more cable than most of the others topologies
