Software Engineering, which means the application of engineering to software, is a method to develop, operate and ________ software. That is, the development of software is on a systematic, _________, quantitive basis. Before starting the development of software, you have to systematically approach the problem. You have to understand the _________ (what the software is supposed to do), carry out the design, do the _________, carry out a rigorous testing and if the software is as per the requirements, release the software to the customer. Subsequently, if the customer wants some changes--refinements or enhancements then the software has to be _________. Passage A The central processing unit (CPU) is the heart of the computer systems. Among other things, its configuration 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 one computer generation has evolved to the next, the physical size of the CPU has often become smaller and smaller, while its speed and cap 1
工学结合创新教程 计算机专业英语 acity 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 the 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, multiplies, 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 executed next. (二) Tell whether the following statements are true(T) or false(F) according to the passage A.(根据上文的内容判断下列句子的正误)(10分,每题2分) 1. With the development of computer, the physical size of the CPU has often become bigger and bigger. ( ) 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. ( ) 3. The CPU comprises the control unit and memory. ( ) 4. The control unit performs all the arithmetic and logical (comparison) functions ( ) 5. The central processing unit (CPU) is the heart of the computer systems. ( ) Passage B In order to solve a computational problem, its solution must be specified in terms of 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. Computer 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 sometimes 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 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? Here's a quick overview of the process:
