UNIX is a multi-user, multitasking operating system originally developed at AT&T Bell Laboratories. It provides programs for editing text, sending electronic mall, preparing tables, performing calculations and many others specialized functions that require separate application programs in other operating systems.
More and more users—writers, scientists, programmers, managers, and others—are using UNIX for jobs such as:
- Text editing and printing
- Document handling and storage
- Programming and software development
- Electronic communication (e-mail, FAX, networking)
- Computer-aided instruction
