In multiprogramming environment, the OS decides which process gets the processor when and for how much time. This function is called process scheduling. An Operating System does the following activities for processor management − Keeps tracks of processor and status of process. The program responsib...
而且还应该在wait(mutex)前 buffer(in):=nextp; // 缓冲池数组游标应前移:in:=(in+1) mod n signal(mutex); // signal(mutex) until false; end consumer: begin repeat wait(mutex); wait(empty) // 应为wait(full), 而且还应该在wait(mutex)前 nextc:=buffer(out); out:=...
This Operating System tutorial contains all the basic to advance topics like Process and I/O Device Management, File and Network Management, Memory Management, Security Management, CPU Scheduling, and more.
Operating system performs the task of scheduling processes based on priorities using these following algorithms: 1.First come first serve (FCFS) In this scheduling algorithm the first process entered in queue is processed first. 2.Shortest job first (SJF) ...
操作系统(Operating System):是控制应用程序执行的程序,它充当用户和计算机之间的接口,并对计算机资源进行管理。 内核(kernel):OS常驻内存的部分,包含了操作系统中最常用的功能。 多道(multiprogramming):当一个程序(作业)被中断需要等待某些事件发生时,CPU可以切换到另一个可以立即运行的程序(作业),这种处理称为多道...

a. Faster program startup b. The existing programs do not need to be re-linked so as to take advantage of the newer library versions c. Lesser page fault rate in a system d. Smaller sizes of executable files Answer:(a) Faster program startup ...
In a Time-sharing system, the CPU executes multiple jobs by switching among them, also known as multitasking. This process happens so fast that users can interact with each program while it is running. 9) What is SMP? SMP is a short form of Symmetric Multi-Processing. It is the most co...
