1.硬件/软件的接口
前五章集中讨论了计算机硬件,现在我们把注意力转向讨论软件。
当记者一想到软件时,也许想到的是应用程序。应用程序支持终端用户的功能,使用户完成如下一些任务。做游戏、写文章、编排一个图表或产生一个账单等。另一类软件称为系统软件,在后台完成赋予它的任务,建立在大量计算机上的例。操作系统作为一个接口提供服务(图6.1),在硬件和应用软件之间搭起了一座桥梁。因此,当我们把注意力从硬件过渡到软件时首先研究操作系统是适合的。
操作系统究意是什么呢?从根本上讲,它完成了大量的支持功能。例如,假设存储在磁盘上的应用程序,在能被执行之前,因为控制计算机的程序必须在主存中,所以必须把它复制到上存中。把程序从磁盘复制到主存的过程涉及重要的逻辑,计算机的逻辑资源就是软件。因此,如果要装入应用程序,必须在主存中有一个控制加载过程的程序,这个程序就属于操作系统。
装入程序仅仅是操作系统大量支持功能中的一个。确切地说,操作系统是一些软件模块的集合,这些模块把用户和硬件隔开,因此使系统容易使用。让我们来研究一般操作系统的基本功能 ......
The Operating System
1. The hardware/Software Interface
The first five chapters focused on a computer's hardware. It's time we turned our attention to software.
When you think of software, you probably think of application programs. They support end-user functions, allowing people to perform such tasks as playing a game, writing a paper, laying out a spreadsheet, or generating paychecks. Another type of software, called system software, performs its assigned tasks behind the scenes. An excellent example is the operating system found on most computers. An operating system serves as an interface, bridging the gap between hardware to software, it's appropriate that we consider the operating system first.
What exactly dose an operating system do? Basically, it performs a number of support funcions. For example, picture an application program stored on disk. Before the program can be executed, it must first be copied into main memory, because the program that controls a computer must be in main memory. The process of copying a program for disk to memory involves considerable logic. The source of a computer's logic is software. Thus, if the application program is to be loaded, there must be a program in memory to control the loading process. That program is the operating system.
Loading programs is only one of the operating system's many support functions. Basically, it is a collection of software modules that insulate the user from the hardware, thus making the system easier to use. Let's investigate the primary functions of a typical operating system ......
