计算机专业与英语密切相关，计算机业界人员必须掌握最新技术，英语水平成为决定工作能力的因素之一。

　　计算机英语其内容具有很强的专业性，与公共英语相比更注重阅读理解能力，只有看懂计算机软硬件安装使用说明手册、计算机屏幕英语提示信息、编程与程序调试过程中的反馈信息才能解决实际问题。只有看懂计算机新技术、新产品的帮助、培训教程，国外原版计算机教材，以及英文文档和技术资料等，才能及时掌握并研究计算机新技术，提高专业水平。

　　本教材内容分三个部分。第一部分基础篇，以单元（Unit）为单位，共10个单元，包括计算机硬件、软件、操作系统、数据、程序设计、计算机科学、多媒体、网络、因特网及在线服务、万维网。每个单元分为术语、单词、短语、缩略词、练习、泛读课文、术语参考译文。习题形式多样，有选择题、匹配题、填空题、翻译题和口语题等。第二部分应用提高篇，内容取材广泛，均选自Apple、Adobe、Microsoft等著名计算机公司及国外计算机技术官方网站。按单元介绍国外计算机学习教程，以及计算机新技术、新软件、新产品、新设备等，如Dreamweaver CC、C语言教程、iPhone手机、Apple计算机、Windows 10新特性、Office 2016新功能等。第三部分附录，提供习题参考答案、专业英语样卷、软件水平考试程序员级专业英语部分试题、构词法和基本句型、学术英语写作常用句子、教材词汇表等。

　　本书选材与时俱进，内容新颖独特，实用性强，叙述简明扼要，难度适中；内容与习题多样化，教学操作性强，易用性强，适合于高校计算机专业英语本科教学使用。本书可以满足不同院校计算机专业英语本科教学需求，也可作为计算机工程人员的参考用书。

　　Operating Systems

　　Part I Computer terms

　　* Operating Systems

　　The operating?system (OS) is the most important program that runs on a computer. Every general-purpose computer must have an operating system to run other programs and applications. Computer operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as printers. Computers and mobile devices must have an operating system to run programs. (ref. Fig.1-3-1)

　　Fig.1-3-1 Operating system

　　For large systems, the operating system has even greater responsibilities and powers. It is like a traffic cop—it makes sure that different programs and?users?running at the same time do not interfere with each other. The operating system is also responsible for?security, ensuring that unauthorized users do not?access?the system.

　　* Multitasking

　　The ability to execute more than one?task?at the same time, a task being a program. The terms multitasking and multiprocessing are often used interchangeably, although multiprocessing mplies that more than one?CPU is involved.

　　In multitasking, only one CPU is involved, but it switches from one program to another so quickly that it gives the appearance of executing all of the programs at the same time.

　　* Multiprocessing

　　Supports running a program on more than one?CPU.

　　* Multi-user

　　Refers to computer systems that support two or more simultaneous users. All?mainframes and minicomputers are multi-user systems, but most personal computers and workstations are not.

　　* Multithreading

　　The ability of an?operating system?to?execute?different parts of a program, called threads, simultaneously. The?programmer?must carefully design the program in such a way that all the threads can run?at the same time without interfering with each other.

　　* Real time

　　?Responds to input instantly. General-purpose operating systems, such as?DOS?and?UNIX, are not real-time.

　　* Linux Operating Systems

　　Linux?is a freely distributed open source operating system that runs on a number of hardware platforms. The Linux kernel was developed mainly by Linus Torvalds and it is based on UNIX.

　　* Windows Operating Systems

　　Microsoft Windows?is a family of operating systems for personal and business computers. Windows dominates the personal computer world, offering a graphical user interface (GUI), virtual memory management, multitasking, and support for many peripheral devices.

　　* Mac Operating Systems

　　Mac OS is the official name of the?Apple Macintosh operating system. Mac OS features a graphical user interface (GUI) that utilizes windows, icons, and all applications that run on a Macintosh computer have a similar user interface.

　　* Control panel

　　A?Macintosh?utility?that permits you to set many of the?system?parameters. For example, you can control the type of beeps the?Mac?makes and the sensitivity of the?mouse.

　　* Mobile operating system

　　A mobile?operating system, also called a mobile OS, is an operating system that is specifically designed to run on mobile devices such as mobile phones, smartphones, PDAs, tablet computers and other handheld devices. The mobile operating system is the software platform on top of which other programs, called application?programs, can run on mobile devices.

　　* Smartphone

　　Smartphones are a handheld?device?that integrates mobile phone capabilities with the more common features of a handheld computer or?PDA. Smartphones allow users to store information,?e-mail, install programs, along with using a mobile phone in one device. For example a smartphone could be a mobile phone with some PDA functions integrated into the device, or vise versa.

　　* NOS—network operating system

　　Abbreviated as NOS, a network operating system includes special functions for connecting computers and devices into a local-area network (LAN). Some operating systems, such as UNIX and the Mac OS, have networking functions built in.
