According to the mode ofprocessing, computers are either analog or digital. They can also beclassified as mainframes, minicomputers, workstations, or microcomputers.All else (for example, the age of the machine) being equal, thiscategorization pro vides some indication of the computer’s speed, size, cost, and abilities.Ever since the advent of computers, there have been constant changes.First-generation computers of historic significance, such as UNIVAC (通用自动计算机), introduced in the early 1950s, were based on vacuum tubes.Second-generation computers, appearing in the early 1960s, were those in which transistors replaced vacuum tubes. In third-generation computers,dating from the 1960s, integrated circuits replaced transistors. In fourth-generation computers such as microcomputers, which first appeared in the mid-1970s, large-scale integration enabled thousands of circuits to beincorporated on one chip. Fifth-generation computers are expected tocombine very-large-scale integration with sophisticated approaches tocomputing, including artificial intelligence and true distributed processing.IV.

第一章Computer system overview(操作系统概述)I. Pre-reading Questions1.What is a digital computer?The digital computer is a digital system that performs various computational tasks. The word “digital”implies that theinformation in the computer is represented by variables that take a limited number of discrete values. These values are processed internally by components that can maintain a limited number of discrete states. Digital computer is also called electronic computer or computer.2.Are there any differences between the binary number system and the common decimal number system?The decimal digits has ten digits: 0,1,2,,, and 9. The binary number system has two digits: 0 and 1. The binary numbers use a base 2. The decimal digits use a base 10.3.How many types of computers do you know? Name at least four of them. Computers are usually classified into four broad categories: microcomputers, minicomputers, mainframe computers and supercomputers.II Fill in the following blanks.1.Application software is designed to accomplish real-world tasks in fields.2. An 8-bit signed integer can have any value between -128 and 1273. System software controls the computer and enables it to run the hardware and applications software.4. A computer system consists of hardware system and software system .5. List four types of computers: microcomputers, minicomputers , mainframe computers,and s upercomputers .III True or False.1. The software system is the physical equipment that you can see and touch. 1.F2. Typically, a data value is set to zero to represent FALSE and 1 value forTRUE. 2.F3. In the earliest general-purpose computer, most input and output media were magnetic disks. 3. F4.T4. Supercomputers are largest, fastest, and most expensive computer available.5.
