What is a PC?
IBM invented
the PC (Personal Computer) way back in 1981. All PCs released since then are in
many ways compatible with the original design, though many extensions have been
made.
The term PC
compatible relates to PCs manufactured by companies other than IBM which are
compatible with the traditional PC specification.
In the early days, most PCs
ran an operating system called DOS (Disk Operating System). These days most PCs
will be running a version of Microsoft Windows.
