Operating System Concepts CPU Protection Timer – interrupts computer after specified period to ensure operating system maintains control. Timer is decremented every clock tick. When timer reaches the value 0, an interrupt occurs. Timer commonly used to implement time sharing. Time also used to comput...
有许多类 system software ,最重要的两类是 operating system 和compiler。OS作为硬件和软件之间的接口,提供服务和监管。OS提供的最重要的功能有 IO,分配存储空间和内存,分时(多个应用共享计算机)。 Complier (编译器)的功能是把高级编程语言翻译成汇编语言(assembly language)(也就是硬件能理解和执行的指令),这个过程...
A computer system consists of hardware components that have been carefully chosen so that they work well together andsoftware componentsor programs that run in the computer. The main software component is itself an operating system (OS) that manages and provides services to other programs that can ...
In this section we examine two examples of layered computer system organization: the hardware layer at the bottom of a typical computer system and one part of the operating system layer that creates the typical application programming interface known as the file system. 2.3.1 A Hardware Layer: ...
Operating system software is part of the computer system, with concurrent, sharing, random, virtual 4 one of the main features. Operating system is a unified management computer software and hardware resources, the rational organization of computer system components between the workflow, coordinatio ...

You can set a Power-On Password, requiring anyone who starts the computer to enter a password before the OS loads. This prohibits hackers from using password-cracking tools to gain entry through the OS. You also can set another password in the Basic Input Output System (BIOS) to prevent ...
