My brother and I are looking into a making websites and running a small home business through the interent, and I'm just wondering, would it be necessary to have a server for it? What would it's use be as such? What parts would it need? I told him it would be a lot more efficient and he isn't so sure. Also, would it need a server processor like a Xeon or an Opteron, or would a normal desktop process (Pentium D) do the job?
