 Time sharing operating system

                       Multi program and batch system provide an environment where the various system resources very well utilize effectively but it did not provide user interaction with the computer system. The time sharing (multi tasking ) is a logical extension of multi program system. The C.P.U. execute multiple jobs by switching among them but swi...............

Multiprogram operating system

                    The most important of the jjob scheduling is the ability to handle multiple job. A single user can not kept either a C.P.U. or the input devices busy at all the time multi-programming increase C.P.U. utilisation by organising jobs . so that the C.P.U. always has one to execute. The operating system keep several job in the memory simonteniously the...............

1. Batch operating system

                       The earlier computer`s where from a console a common input device where card reader and tape drives and the common output devices when Line printer,Tape drives and Card punches. The user didn`t interact directly with the computer system. The user prepared a job which consist the program, data and some controlled information about...............
