Theory Of Distributed Computing And Parallel Processing With Its Applications, Advantages And Disadvantages.

Distributed computing is a field of computer science that studies distributed systems. A distributed system consists of multiple autonomous computers that communicate through a computer network. The computers interact with each other in order to achieve a common goal. A computer program that runs in a distributed system is called a distributed program, and distributed programming is the process of writing such programs .There are several autonomous computational entities, each of which has its own local memory. •The entities communicate with each other by message passing. •The system has to tolerate failures in individual computers. •The structure of the system is not known in advance, the system may consist of different kinds of computers and network links, and the system may change during the execution of a distributed program. •Each computer has only a limited, incomplete view of the system. Each computer may know only one part of the input
