These services can be classified either as “external” or “internal.” The operating system provides external services that help users start programs, manage stored data, and maintain security. You, as the computer user, control these external functions. Using a command-line, menu-driven, or GUI user interface, an operating system provides you with a way to select the programs you would like to use. The operating system also helps you find, rename, and delete documents and other data stored on disk or tape. On many, but not all computer systems, the operating system helps you maintain security by checking your user ID and password, as well as protecting your data from unauthorized access and revisions. The operating system provides internal services “behind the scenes” to ensure that the computer system functions efficiently. These internal services are not generally under your control, but instead are controlled by the operating system itself. The operating system controls input and output, allocates system resources, manages the storage space for programs and data, and detects equipment failure without any direction from you. simultaneous access 同时访问 command-line interface 命令行界面 multitasking environment 多任务化环境 spreadsheet program 电子制表程序 main memory 主存 storage media 存储介质 disk file 磁盘文件 command interpreter 命令解释器 network connection 网络连接 DOS (disk operating system) 磁盘操作系统 copy a data file 拷贝数据文件 Section B I．Fill in the blanks with the information given in the text: 1． UNIX 2． Networking

It lets the programmer express data processing in a symbolic manner without regard to machine-specific details. The difficulty of writing programs in the machine language of 0s and 1s led first to the development of assembly language, which allows programmers to use SQL 结构化查询语言 executable program 可执行程序 program module 程序模块 conditional statement 条件语句 assignment statemen t赋值语句 logic language 逻辑语言 machine language 机器语言 procedural language 过程语言 programming language 程序设计语言 run a computer program 运行计算机程序 20． computer programme r 计算机程序设计员 23

mnemonics for instructions and symbols for variables. Such programs are then translated by a program known as an assembler into the binary encoding used by the computer. Other pieces of system software known as linking loaders combine pieces of assembled code and load them into the machine’s main memory unit, where they are then ready for execution. The concept of linking separate pieces of code was important, since it allowed “libraries” of programs to be built up to carry out common tasks—a first step toward the increasingly emphasized notion of software reuse. Assembly language was found to be sufficiently inconvenient that higher-level languages (closer to natural languages) were invented in the 1950s for easier, faster programming; along with them came the need for compilers, programs that translate high-level language programs into machine code. As programming languages became more powerful and abstract, building efficient compilers that create high-quality code in terms of execution speed and storage consumption became an interesting computer science problem in itself.
