time in a useful manner. A single-threaded process‚ on the other hand‚ will not be capable of performing useful work when a page fault takes place. Therefore‚ in scenarios where a program might suffer from frequent page faults or has to wait for other system events‚ a multi-threaded solution would perform better even on a single-processor system. 4.4 Which of the following components of program state are shared across threads in a multithreaded process? a. Register values b. Heap memory c. Global

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 latter is available. 3.

technique is that the auditor does not have an assurance that the program tested is the same program used by the client throughout the accounting process. . In order to overcome this disadvantage‚ the test data technique can be extended to an integrated test facility (ITF) An integrated test facility (ITF) creates a fictitious entity in a database to process test transactions simultaneously with live input. It can be used to incorporate test transactions into a normal production run of a system.

between preemptive and nonpreemptive scheduling. Answer: Preemptive scheduling allows a process to be interrupted in the midst of its execution‚ taking the CPU away and allocating it to another process. Nonpreemptive scheduling ensures that a process relinquishes control of the CPU only when it finishes with its current CPU burst. Suppose that the following processes arrive for execution at the times indicated. Each process will run for the amount of time listed. In answering the questions‚ use nonpreemptive
