DEFINITION
What is a Network ?
A network is simply two or more computers that are linked together.

STAR TOPOLOGY
All devices connect to acentral device, calledhub.
All data transferredfrom one computer toanother passes through hub.

ADVANTAGE DISADVANTAGE
1) Easy to install and wire. 1) Requires more cable length
than a linear topology.
2) If any node or cable fails,
other nodes are not effected.
2) If the hub or concentrator
fails, nodes attached are
disabled.
3) Easy to detect faults and to
remove parts.
3) More expensive than linear
bus topologies because of
the cost of the hubs.

BUS TOPOLOGY
All computers and devices connected to central cable or bus.
The central cable is the backbone cable.
The devices or nodes are attached with the bus through interface connecter.

ADVANTAGE DISADVANTAGE
1) Easy to connect computer or
peripheral to a linear bus.
1) Entire network shuts down if
there is a break in the main
cable.
2) Requires less cable length
than a star topology.
2) Terminators are required at
both ends of the backbone
cable.
3) If one node fails, other nodes
are not effected.
3) Difficult to identify the
problem if the entire network
shuts down.

RING TOPOLOGY
In ring topology, each computer is connected to the next computer and the last is connected to the first.
Data travels from device to device around entire ring, in one direction.
In this way, the last node connects to the first to complete the ring.

ADVANTAGE DISADVANTAGE
1) It is less expensive than star topology.
1) Adding or removing a computer from network effects the whole networks.
2) It is easy to install and to
maintain.
2) If any of the nodes fail then the
ring is broken and data cannot
be transmitted successfully. 3) It is difficult to troubleshoot
the ring.
