分时系统(time-sharing system):分时系统允许多个用户通过终端同时访问系统,共享CPU时间,操作系统以时间片为单位,轮流为每个终端用户服务,提供了较好的交互性。 批处理系统(Batch Processing System):批处理是指计算机操作员将作业组织成批,提交给操作系统,由操作系统控制它们自动运行。这种采用批处理技术的操作系统称为...
The operating system is responsible for the following activities in connection withprocess management: Creating and deleting both user and system processes Scheduling processes and threads on the CPUs Suspending and resuming processes Providing mechanisms for process synchronization ...
Operating System 08 - 进程与线程 进程与线程 进程 进程是资源分配的基本单元. 进程控制块(Process Control Block,PCB)描述进程的基本信息和运行状态, 所谓的创建进程和撤销进程, 都是对于PCB的操作. 线程 线程是独立调度的基本单位. 一个进程中可以有多个线程, 他们共享进程资源....
system the executable resides, calls fork() to create a new child process to run the command, calls some variant of exec() to run the command, and then waits for the command to complete by calling wait(). When the child completes, the shell returns from wait() and prints out a ...
is kernel thread. In this type of system, the user-level threads are supported above the kernel and managed without kernel support, whereas kernel threads are directly supported and managed by the help of an operating system. On the basis of it there are generally three types of model ...
