Wireless Adapter Needed?

[megalizardfish]

Hi, I'm building a computer, and do I need to buy a wifi adapter? I thought that the internet section of a computer was integrated into the motherboard. Any help would be appreciated. Thanks.

You need a WiFI adapter only if you are going to connect via WiFi. Some few motherboards have it built in, but only a very few.
Almost all current boards have the RJ-45 LAN port built in, for an ethernet cable.
