The electric,electronic, and mechanical devices used for processing data are referred to as hardware. In additionto the computer itself, the term "hardware¡±refers to components called peripheral devices thatexpand the computer's input, output, and storage capabilities. Computer hardware in and of itselfdoes not provide a particularly useful mind tool. To be useful, a computer requires a set ofinstructions, called software or a computer program, which tells the computer how to perform aparticular task. Computers become even more effective when connected to other computers in anetwork so users can share information.2. Many schools and businesses have established e-mail privacy policies, which explain the=================================================================================================== condition under which you can and cannot expect your e-mail to remain private. These policies aresometimes displayed when the computer boots or a new user logs in. Court decisions, however,seem to support the notion that because an organization owns and operates an e-mail system, thee-mail message on that system are also the property of the organization. The individual who authorsan e-mail message does not own all rights related to it. The company or school that supplies youre-mail account can, therefore, legally monitor your messages. You should use your e-mail accountwith the expectation that some of your mail will be read from time to time. Think of your e-mail asa postcard, rather than a letter, and save your controversial comments for face-to-faceconversations.3£®Multitasking, in computer science, is a mode of operation offered by an operating system inwhich a computer works on more than one task at a time. There are several types of multitasking.Context switching is a very simple type of multitasking in which two or more applications areloaded at the same time but only the foreground application is given processing time; to activate abackground task, the user must bring the window or screen containing that application to the front.In cooperative multitasking, background tasks are given processing time during idle times in theforeground task (such as when the application waits for a keystroke), and only if the applicationallows it. In time-slice multitasking, each task is given the microprocessor's attention for a fractionof a second. To maintain order, tasks are either assigned priority levels or processed in sequentialorder. Because the user's sense of time is much slower than the processing speed of the computer,time-slice multitasking operations seem to be simultaneous.4. One especially powerful feature of OOP (objected-oriented programming) languages is aproperty which is known as inheritance. Inheritance allows an object to take on the characteristicsand functions of other objects to which it is functionally connected. Programmers connect objectsby grouping them together in different classes and by grouping the classes into hierarchies. Theseclasses and hierarchies allow programmers to define the characteristics and functions of objectswithout needing to repeat source code, the coded instructions in a program. Thus, using OOPlanguages can greatly reduce the time it takes for a programmer to write an application, and alsoreduce the size of the program. OOP languages are flexible and adaptable, so programs or parts ofprograms can be used for more than one task. Programs written with OOP languages are generallyshorter in length and contain fewer bugs, or mistakes, than those written with non-OOP languages.5. In software, a bug is an error in coding or logic that causes a program to malfunction or toproduce incorrect results. Minor bugs-for example, a cursor that does not behave as expected-canbe inconvenient or frustrating, but not damaging to information. More severe bugs can cause aprogram to "hang¡± (stop responding to commands) and might leave the user with no alternativebut to restart the program, losing any previous work that has not been saved. In either case, theprogrammer must find and correct the error by the process known as debugging. Because of thepotential risk to important data, commercial application programs are tested and debugged ascompletely as possible before release. Minor bugs found after the program becomes available arecorrected in the nest update; more severe bugs can sometimes be fixed with special software, called=================================================================================================== patches, that circumvents the problem or otherwise reduces its effects.²Î¿¼´ð°¸£º´ð°¸¼û½Ì²Äÿ¿ÎºïµÄ²ÒëÁ²Ï°´ð°¸¡£1：[论述题]请选择下列一个题目写一篇不低于150个词的英文短文.1.
