The chip is, in a sense, the 'brain' of the computer. it plugs into a special slot in the the C.P.U. and processes all the computers data. The chip's speed is measured in Megahertz (mhz) the more mhz the chip has, the faster it is.
There are three main types of chips, Celeron, Pentium and A.M.D. There are no distinct differences between the three, just different brands, although, Pentium is the most widely known and is suported by most, if not all, software companies.
