UNIX is an extremely popular operating system and dominates in the high-powered, multitasking workstation market. It is relatively simple to use and to administer, and also has a high degree of security. UNIX computers use TCP/IP communications, which they use to mount, disk resources from one machine onto another. Its main characteristics are:
  • Multi-user.

  • Preemptive multitasking.

  • Multiprocessing.

  • Multithreaded applications.

  • Memory management with paging (organizing programs so that the program is loading into pages of memory) and swapping (which involves swapping the contents of memory to disk storage).
