4、on 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 one computer generation has evolved to the next,the physical size of the CPU has often become smaller and smaller,while i

5、ts speed and capacity have increased tremendously.Indeed,these changes have resulted in microcomputers that are small enough to fit on your desk or your lap.The CPU comprises the control unit and the arithmetic/logic unit(ALU).The control unit is responsible for directing and coordinating most of th

6、e computer systems activities.It determines the movement of electronic signals between main memory and the arithmetic/logic unit,as well as the control signals between the CPU and input/output devices.The ALU performs all the arithmetic and logical(comparison)functions that is,it adds,subtracts,mult

7、iplies,divides,and does comparisons.These comparisons,which are basically“less than”,“greater than”,and“equal to”,can be combined into several common expressions,such as“greater than or equal to”.The objective of most instructions that use comparisons is to determine which instruction should be exec

8、uted next.(1).With the development of computer,the physical size of the CPU has often become bigger and bigger.B (2).The movement of electronic signals between main memory and the ALU as well as the control signal between the CPU and input/output devices are controlled by the control unit of the CPU

9、.A (3).The CPU comprises the control unit and memory.B (4).The control unit performs all the arithmetic and logical(comparison)functions.B (5).The central processing unit(CPU)is the heart of the computer systems.A 1.In order to solve a computational problem,its solution must be specified in terms of

10、 a sequence of computational 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 developing programs for the solution of computational problems is referred to as programming.C

11、omputer programming 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 out otherwise.So programming is breaking a task down into small steps.Programming is someti

12、mes contrasted with coding.Coding generally refers to the writing of programs for given program specification,while programming includes the task of preparing the program specification as well as that of writing the program.The text of a program is sometimes referred to as code,and lines of program

13、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.Whats actually involved in programming-the actual process of writing programs?Heres a qu

14、ick overview of the process:Write a program.Compile the program.Run the program.Debug the program.Repeat the whole process until the program is finished.(1).If you want to solve the computational problem with a computer,you should learn how to .B program (2).Computer programming is the process of pl

15、anning and creating a sequence of for a computer to follow.A steps (3).The term coder is used to describe .D person (4).In order to solve a computational problem,you can let a person or a to do it.B computer (5).Which of the following is not the stages of programming?A Write a program.C Print the program.参考答案：C；考生答案：C；试题分数：4；考生得分：4￥:
