There is essentially two ways of setting up a home network, wired or wireless.

A wired network involves connecting up the computers using cables, and if often referred to as an Ethernet network. An Ethernet network transfers data at high speeds, faster than wireless networks as it is very rare for the connection to be interrupted. Although data transfer speeds of 1 Gbps can be achieved, the average speed is 100 Mbps, and this is why you will often see "10/100" next to Ethernet ports on computers or in product data specs.
