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

14、 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 AThe central processing unit (CPU) is the heart of the computer systems. Among other things, its configur

15、ation 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 phys

16、ical size of the CPU has often become smaller and smaller, which its speed and capacity have increased tremendously. Indeed, these changes have resulted in micro-Computers that are small enough to fit on your desk and your lap.The CPU comprises the control unit and the arithmetic/logic unit (ALU).Th

17、e 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 a

18、rithmetic and logical(comparison) functionsthat is, it adds, subtracts, multiplies, divides, and does comparison. 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

19、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%)1. With the development of computer, the physical size of the CPU has often become bigg

22、cts, ranging from the annoying to the disastrous. Virus attacks are growing rapidly these days. According to Business Week, the 76,404 attacks reported in the first half of 2003 nearly match previous years total number. As new antivirus tools are more powerful than before, the virus writers are gett

23、ing a lot smarter with newer and creative ways to attack network systems. Lets first examine some common virus types: Basic Virus a piece of software code that is developed to attack computers and network systems via email or Internet connections. It quickly replicates itself and gradually attaches

24、to files, programs or the hard drive.Trojan Horses - This is a program that doesnt replicate when entering a system but can be effectively used to open back doors. Trojan Horses allow hackers to take control over a particular system or to steal very important data.Worm - this type of virus is able t

25、o spread itself automatically over the network from one computer to the next. During a worm attack, users computers get infected without even having to click open email attachment or any program, etc.Since it is very difficult to avoid the virus, your best defense is a powerful antivirus program. In

26、 order to fight with such viruses, the software vendors should focus on making their products more robust. This may ask for a trade-off between user-friendliness and security. In specific cases it may require line-by-line inspection, code retooling and even systems automation to defend the installed

30、 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 proble

31、ms 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 in
