内工大计算机英语试卷部分考题
单词填空1、A digital computer is generally made up of five distinct elements: a central processing unit, input devices, memory storage devices, output devices, and a bus.2、The two most common types of scanners are flatbed scanners and hand-held scanners.3、We can classify programming languages under two types: low-level languages and high-level languages.4、There are three types of application programs to translate source code into object code. They are compilers, interpreters, and assemblers.5、The three generic process models discussed in the text are often complementary rather than mutually exclusive especially for large systems development.6、According to the text, a DBMS is a combination of five components: hardware, software, data, users, and procedures.7、According to the geographical area covered, a computer network is often classified as either a LAN, an MAN, or a WAN.2 完形填空A program is a sequence of instructions that tells the hardware of a computer what operations to perform on data. Programs can be built into the hardware itself,or they may exist independently in a form known as software. In some specialized, or “dedicated”, computers the operating instructions are embedded in their circuitry; common examples are the microcomputers found in calculators, wristwatches, car engines, and microwave ovens.A general-purpose computer, on the other hand, although it contains some built-in programs (in ROM) or instructions (in the processor chip), depends on external programs to perform useful tasks. Once a computer has been programmed, it can do only as much or as little as the software controlling it at any given moment enables it to do. Software in widespread use includes a wide range of applications programs----instructions to the computer on how to perform various tasks.One continuing trend in computer development is microminiaturization, the effort to compress more circuit elements into smaller and smaller chip space. Researchers are also trying to speed up circuitry functions through the use of superconductivity, the phenomenon of decreased electrical resistance observed in certain materials at very low temperatures.3 翻译人工智能 artificial intelligence 计算机体系结构 computer architecture单独 individual软件开发生命周期 software development life cycle。
