Distributed Operating System is an operating system that resides on the network rather than individual workstations. Much operating system research is focused on developing Plan 9. See operating system (OS), Plan 9. A distributed processing system of a computer system is designed for multiple users that provides each user with a fully functional computer.
In personal computing, distributed processing takes the form of local area networks (LANs), in which the personal computers of the members of a department or organization are linked by high-speed cable connections. Distributed processing offers some advantages over multiuser systems. If the network fails, a person can still work. One also can select software tailored to his or her needs. One can start a distributed processing system with a modest initial investment because he or she needs only two or three workstations and, if desired, a central file server.
