Unit IX: Distributed Operating System | BCA 4th Semester Operating System Notes Pdf

A computing system composed of large numbers of CPUs connected by a network is known as the distributed system. In other words, a distributed system can be defined as a collection of autonomous computers linked by a network with software designed to produce an integrated computing facility (or equipped with distributed system software).
