The academy uses a star network. A star network is a network topology that has all devices separate from each other connecting at a switch. It takes more cabling to set up a star network because of the individual connections to each device but it brings the advantage that if one device goes down it wont effect the rest of the network unless its a switch.

3aaa network runs from the server which then goes to a switch, which then has connections to each device creating a star network.

It is slower than a star topology because each packet of data needs to travel around the ring until it reaches its destination.

If one device goes down the whole network is affected.

This network is very dependant on the cable that connects devices.

Data travels in one direction at high speeds.

Even when under pressure it performs better than a bus topology.

A server isn't needed for the control of connectivity between devices.

Every computer has equal access.

Additional devices don't effect the performance.

A token ring network is a LAN that stops data collision by sending a token around the ring. a user can only send data when they are holding the token.

A network topology is the way your network works, it is the design it uses to transfer data for example bus, star, mesh.
