3) STAR NETWORK
DIAGRAM OF STAR NETWORK:
DEFINITION/PHYSICAL TOPOLOGY OF 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/HOW DATA TRANSMIT |
In a star network, data, instructions, and informations transfer from one node to another node passes through hub/switch. If the network used hub, the signal will send to all nodes but only the intended recipient will accept the signal and the rest will ignore.
If the network used switch, the signal will send directly to the intended recipient.
|
ADVANTAGES OF STAR NETWORK
1. If one device (pc/printer) fails, only that device is affected.
2. Devices (pc/printer) can be added to or removed from network with little or no disruption.
3. Easy to troubleshoot and isolate problem.

DISADVANTAGES OF STAR NETWORK
1. The network will be malfunctioned if the single hub/switch break down.
2. Requires more cable than most of the other topologies.
