The star network
In a star network each device on the network has its own cable that connects to a switchor hub. A hub sends every packet of datato every device, whereas a switch only sends a packet of data to the destination device.
A star network, where devices are connected to a central hub or switchAdvantages and disadvantages of a star network
The advantages of a star network are:
- it is very reliable if one cable or device fails then all the others will continue to work
- it is high-performing as no data collisions can occur
The disadvantages of a star network are:
- it is expensive to install as this type of network uses the most cable [network cable is expensive]
- extra hardware is required [hubs or switches] which adds to cost
- if a hub or switch fails, all the devices connected to it will have no network connection
