We can view an operating system as a resource allocator. Explain.
We can outlook an operating system as a resource allocator. A computer system has Many resources (software and hardware) that may be necessary to solve a problem: memory space,I/O devices, CPU time, and so on. The operating system acts as the manager of these resources and allocates them to specific programs and users as necessary for tasks. Since there perhaps many-possibly conflicting-requests for resources, the operating system ought to decide which requests are allocated resources thus that it can operate the computer system efficiently and fairly.
A slightly different view of an operating system gives emphasis to the need to control the various I/O devices and user programs. An operating system (OS) is a control program. A control program controls the carrying out of user programs to prevent improper use and errors of the computer. It is principally concerned with the operation and control of I/O devices.
LRU approximation page replacement In this we utilize the reference bit associated with the page entry to choose a page to be removed. The various algorithms used for the imp
What are the necessary conditions for deadlocks? 1. Mutual exclusion : Only one process at a time is able to use the resource. 2. Hold and wait : A process should be holdi
Q. Explain the Concept of Process? A process is sequential program in execution. A process states the basic unit of computation for the computer. Components of process are:
Second chance Algorithm When the page is chosen the reference bit is checked to see whether it has been referenced before. If that is the case after that it is given a second c

Gang Scheduling : A set of related process is scheduled to execute on a set of processors at the similar time, on a 1-to-1 basis. Closely related processes or threads may be sched
Medium term scheduling This is component of the swapping function. Usually the swapping in decision is based on the need to manage the degree of multiprogramming. At a system t
