Paging is solution to external fragmentation problem which is to permit the logical address space of a process to be noncontiguous, thus allowing a process to be allocating physical memory wherever the
Switching the CPU to another process requires saving the state of the old process and loading the saved state for the new process. This task is known as a context switch.Context-switch time is pure overhead,
Distribute the computation among several physical processors.Loosely coupled system – each processor has its own local memory; processors communicate with one another through various communications
Latest Answer : Distributed system in genral refers to n/w o.s in which various systems (computers) are connected to sharing some of resources like printer etc. Each system have own data (including files etc) and whenever access over other's system data is required FTP ...
