 | | The UNIX operating system, unlike the operating systems on most personal computers, is a multiuser, multitasking operating system. The first term, multiuser, means that more than one person can use the system at the same time to get work done. The second term, multitasking, means that the system as a whole, and each user individually, can do more than one thing at a time. Contrast this with a personal computer, which supports one user at a time, using one program at a time. | |
