【正文】 erentiating characteristic. In fact, as the rate of personal puter sales growth flattened during the mid1980s, softwareproduct sales continued to grow. Many people in industry and at home spent more money on software than they did to purchase the puter on which the software would run. 5 The fourth era in puter software is just beginning. Objectoriented technologies (Chapters 8 and 12) are rapidly displacing more conventional software development approaches in many application areas. Authors such as Feigenbaum and McCorduck [FEI83] and Allman [ALL89] predict that fifthgeneration puters, radically different puting architectures, and their related software will have a profound impact on the balance of political and industrial power throughout the world. Already, fourthgeneration techniques for software development (discussed later in this chapter) are changing the manner in which some segments of the software munity build puter programs. Expert systems and artificial intelligence software has finally moved from the laboratory into practical application for wideranging problems in the real world. Artificial neural work software has opened exciting possibilities for pattern recognition and humanlike information processing abilities. As we move into the fourth era, the problems associated with puter software continue to intensify: Hardware sophistication has outpaced our ability to build software to tap hardware39。 1 外文翻譯 : Software and software engineering the software appearance and enumerates As the decade of the 1980s began, a front page story in business week magazine trumpeted the following headline:” software: the new driving force.”software had e of age—it had bee a topic for management concern. during the mid1980s,a cover story in foreune lamented “A Growing Gap in Software,”and at the close of the decade, business week warned managers about”the Software Trap—Automate or else.”As the 1990s dawned , a feature story in Newsweek asked ”Can We Trust Our Software? ”and The wall street journal related a major software pany’s travails with a front page article entitled “Creating New Software Was an Agonizing Task …” these headlines, and many others like them, were a harbinger of a new understanding of the importance of puter software the opportunities that it offers and the dangers that it poses. Software has now surpassed hardware as the key to the success of many puterbased systems. Whether a puter is used to run a business, control a product, or enable a system , software is the factor that differentiates . The pleteness and timeliness of information provided by software (and related databases) differentiate one pany from its petitors. The design and “human friendliness” of a software product differentiate it from peting products with an otherwise similar function .The intelligence and function provided by embedded software often differentiate two similar industrial or consumer products. It is software that can make the difference. During the first three decades of the puting era, the primary challenge was to develop puter hardware that reduced the cost of processing and storing data .Throughout the decade of the 1980s,advances in microelectronics resulted in more puting
