Вариант 4 1.Перепишите и письменно переведите предложения. Подчеркните в каждом из них модальные глаголы. 1. One program often cannot read data created in another program unless the receiving program translates the other program’s codes. 2. Programs written for one processor may not be compatible with a processor that is designed differently. 3. You should learn how to evaluate a processor’s speed. 4. Programs must be written using instructions recognized by the CPU. 5. The exception is to have programs written for a particular operating system and then have the operating system tailored to fit the CPU. 2.Перепишите предложения, вставьте в них следующие модальные глаголы: should, can, need to, might, must. Письменно переведите предложения. 1. A photograph or drawing … be digitized by treating it as a series of colored dots. 2. Microprocessor manufacturers…carefully to consider compatibility when introducing new models. 3. You …know some key points about processors. 4. If a read-write head runs into a dust particle or some other contaminant on the disk it …cause a head crash, which damages some of the data on the disk. 5. Buying a computer, you’ll …assess your budget. 3.Перепишите предложения, переведите их, обратив внимание на различные функции местоимения it. 1. The bus interface unit retrieves the instruction from RAM and passes it along to the prefetch unit. 2. Random-access memory is fast, but it has one drawback, it is volatile. 3. Hardware is the equipment – it includes storage and memory. 4. It doesn’t matter whether someone else thinks that a feature isn’t necessary; it may be necessary for you. 5. If you want a feature but it is too expensive to purchase now, look for a system that can be easily expanded. 4. Перепишите предложения, исправив ошибки; письменно переведите предложения. 1. Can computer hardware being divided into four categories: input, processing, storage, output? 2. Do programs must be written using instructions recognized by that CPU? 3. You may to be surprised to learn that people are part of the computing process. 4. It should being noticed that learning on a computer can be fun. 5. UNIVAC I is the example of the computers which could performed thousands of calculations per second. 5. Перепишите предложения, поставьте модальные глаголы в форме: а) прошедшего времени; б) будущего времени. 1. Business minicomputers can perform to 100 million operations per second. 2. Programmers must write application programs in a way that computers can understand. 3. Microsoftware may also include microinstruction manual, microassembler, etc. 4. The instructions are to be written according to a set of rules. 5. The computer cannot understand instructions written in just any old way. 6. Прочтите и письменно переведите текст. Hardware The purpose of storage hardware is to store computer instructions and data in a form that is relatively permanent and retrieve when needed for processing. Storage hardware serves the same basic functions as do office filing systems except that it stores data as electromagnetic signals. The most common ways of storing data are hard disk, floppy disk and CD-ROM. Hard disk is a rigid disk coated with magnetic material, for storing programs and relatively large amounts of data. Floppy disk – thin, usually flexible plastic disk coated with magnetic material, for storing computer data and programs. CD-ROM (compact disk read-only memory) is a compact disk on which a large amount of digitized read-only data can be stored. CD-ROMs are very popular now because of the growing speed which CD-ROM drives can provide nowadays. The purpose of output hardware is to provide the user with the means to view information produced by the computer system. Information is output in either hardcopy or softcopy form. Hardcopy output can be held in your hand, such as paper with text (word or numbers) or graphics printed on it. Softcopy output is displayed on a monitor. Monitor is a component with a display screen for viewing computer data or television programs. Printer is a computer output device that produces a paper copy of data or graphics. Modem is an electronic device that makes possible the transmission of data to and from computer via telephone or other communication lines. Hardware comes in many configurations, depending on what the computer system is designed to do.
