5、software, is a method to develop, operate andsoftware.That is, the development of software is on a systematic, , quantitive basis. Before starting the development of software, you have to systematically approa ch the problem. You have to understand the(what the software is supposed to do), carry o u

6、t the design, do the, carry out a rigorous testing and if the software is as per the require ments, release the software to the customer. Subsequently, if the customer wants some changes-refine ments or enhancements then the software has to be.Passage AThe central processing unit (CPU) is the heart

7、of the computer systems. Among other things, its c onfiguration determines whether a computer is fast or slow in relation to other computers. The CPU is the most complex computer system component, responsible for directing most of the computer system activities based on the instructions provided. As

8、 one computer generation has evolved to the next, t he physical size of the CPU has often become smaller and smaller, while its speed and capacity have in creased tremendously. Indeed, these changes have resulted in microcomputers that are small enough to fit on your desk or your lap.The CPU compris

9、es the control unit and the arithmetic / logic unit (ALU).The control unit is responsible for directing and coordinating most of the computer systems activi ties. It determines the movement of electronic signals between main memory and the arithmetic/logic unit, as well as the control signals betwee

10、n the CPU and input/output devices.The ALU performs all the arithmetic and logical (comparison) functions that is, it adds, subtra cts, multiplies, divides, and does comparisons. These comparisons, which are basically“less than”, “greater than”, and “equal to”, can be combined into several common ex

11、pressions, such as“gre ater than or equal to”. The objective of most instructions that use comparisons is to determine which instruction should be executed next.二Tell whether the following statements are true(T) or false(F) according to the passage A.文的内容推断以下句子的正误10 分,每题 2 分依据上1.

14、tational steps, each of which may be performed by a human or a digital computer . If you want to solve the computational problem with a computer, you should learn how to program. The task of d eveloping programs for the solution of computational problems is referred to as programming. Compu ter prog

15、ramming is the process of planning and creating a sequence of steps for a computer to follow. In general, this process will help us resolve a problem, which is either too tedious or difficult to work o ut otherwise . So programming is breaking a task down into small steps.Programming is sometimes co

16、ntrasted with coding. Coding generally refers to the writing of progr ams for given program specification, while programming includes the task of preparing the program sp ecification as well as that of writing the program. The text of a program is sometimes referred to as cod e, and lines of program

17、 text are referred to as lines of code, especially in the case of machine-language programs. The term coder is used to describe a person engaged exclusively in implementing program specifications prepared by others.What”s actually involved in programming - the actual process of writing programs?

It quickly replicates itself and gradually attaches to files, progra ms or the hard drive.Trojan Horses - This is a program that doesn”t replicate when entering a system but can be effectively used

24、 to open ”back doors.” Trojan Horses allow hackers to take control over a particular syst em or to steal very important data.Worm - this type of virus is able to spread itself automatically over the network from one comput er to the next. During a worm attack, users” computers get infected without e
