I think what you are asking is whether there is a difference between personal computers and computers that you find in businesses. This is a hard question to answer, unless I know what type of business you are referring to. For example, if you are talking about a high technology science company with the need to make huge computations, a personal computer would not work. Or if you are referring even to a movie production company that needs to render huge amount of video footage. But if you are referring to average companies, then any computer would work fine. The difference is not so much in the hardware. The difference is in the software.
