and a google search will get you what you need. Basically, however, a full implement of gigabit Ethernet will require that all devices and connections that you desire to transmit at that speed be compliant with gigabit standards. This means the cables and connector too. Any hardware in the high speed path needs to support gigabit. Now, you will read that there is hardware that supports gigabit and that which is certified for it. One difference between Cat5e and Cat6 is that 5e supports it but Cat6 is certified for it. This isn't going to mean that things such as printers and devices that are branched on the LAN and run at 10/100 are going to pull down the whole network. But, if you want to send/receive data from one PC to another on your home LAN at the gigabit rate, both PCs will need NICs that support it as well as the cabling and switch between them. You're not going to pick up any internet speed, however, as even today's broadband available for homes (with the possible exception of fiber optic systems) runs at speeds even base 10 can handle. Hope that helps.
