=== Crossover cables ===

 

For normal networking only the Orange and Green pairs are used.

Normally a cable is straight, i.e.

the same wiring at each end - pin 1 to pin 1, pin 2 to pin 2, etc.

You can connect hubs together, but as a general rule you should not have more than 4 hubs from any one machine to any other as the accuracy and delay of the signals cannot be guaranteed and the network might not work properly.

Hubs are very simple to use as you just plug a patch lead between a port on the hub and the PC.<br>

=== Uplink ===

 

=== Full duplex ===

 

This means you can send and receive data at the same time on a port.

This again adds performance, but it only works where the PC can handle full duplex.
