Beside simply technical build home network we learned before ( read here ), you’re also going to need Network Interface Cards (or NICs) in each computer, printer or any other device you want to be on the network. These can be your standard 10/100 ethernet cards or 802.11b/g cards which can be used for a wireless network. If you are building a wired network, you can use Ethernet equipment with 10MB or 100MB speeds.

They are both so inexpensive, that there is really no reason not to go for the 100MB equipment. These devices generally support equipment which runs in the older standard as well. There is also Gigabit Ethernet, but this is prohibitively expensive for many building a home network.
