Disconnecting Network Drive

Do I need Network Drive,I read an article that said I could speed up my computer if I Disconnected Network Drive. I do not do any Networking,could someone explain what would happen if I disconnected it,is it shared with other programs. I just what to learn and also if I can speed up the PC that would be a good tweak.

XP Pro
640 Mb Ram
40 G Hard Drive
