The personal computer has come a long way in a relatively short time, and much of the progress is due to the continuing advancements in operating systems. Over the past twenty years, the evolution in operating systems has made PCs easier to use and understand, more flexible, and more reliable. Today, in addition to the operating systems that consume hundreds of megabytes of disk space on personal computers, miniaturized operating systems fit onto tiny portable digital assistants (PDA´s) and even cellular telephones.

Many early computers ran under operating systems, such as CP/M, which are no longer used. As PCs came into common usage in homes and businesses, the vast majority of them ran DOS- a much maligned, command-line-based operating system that still is present to one extent or another in most versions of windows. Now, as in the past, many PCs run under some version of UNIX, which is one of the richest and most enduring operating systems.

Users have several choices when it comes to operating systems, although the choice is not always easy. The vast majority of new PCs are sold with some version of Windows installed, but many users (especially in business) are choosing to run UNIX or Linux.
