If the hub/switch fails then the whole network will fail

Cost - More hardware is needed (hub/switch)

Uses a lost of cable which adds to cost

If one computer on the network fails, no issues are caused for anyone else

There are no data collisions so high performance

A Star Network is one of the most commonly used topologies, where all the devices (nodes) connect to a central hub or switch.

All information on the network goes through the hub or switch, this then manages all the data transported around the network. Each node has it's own individual cable connecting it to the hub or switch.

Computer Networking Tutorial - 12 - Bus Topology

If one wire fails, the whole network will fail

The more computers are added to the network, the slower data will be sent across it

A bus network may not work well if the nodes are located at scattered points that do not lie near a common line.

All computers on the network have access to all the data on it, which could be a security risk

Easy to install

Easy to connect computers to the network at any time, and anywhere on the network

Cheap to install - requires less cable than a star topology

If one computer on the network fails, no issues are caused for anyone else

A Bus Network is a type of LAN network arrangement where each device (node) is connected to a main cable.

There is a terminator on each end of the bus network. This stops any no-longer needed information from running back down the network. This means that most of the time, only necessary information is being passed through the network so it increases the efficiency of the network and it prevents the signals bouncing back and forth
