计算机是当代推动生产力发展最为积极的因素,它几乎已经深入到人类生产和生活的一切领域,引起了经济结构、社会结构和人们生活方面。
计算机是当代推动生产力发展最为积极的因素,它几乎已经深入到人类生产和生活的一切领域,引起了经济结构、社会结构和人们生活方式的急剧变化。在短短四十多年的时间里,其应用就遍及4000多个行业,用途超过5000多种,而且还在不断发展着新的应用。这些应用可以归纳为以下几大类:
一、数值计算
这是计算机最早的应用领域。在现代科学研究和工程技术中,有各种复杂的数学问题,如果由人工计算,不但耗时费力,而且难以及时提供准确的数据。计算机的高速度、大容量等特性为解决这些庞大、复杂的计算问题提供了可能。
在气象预报,天文研究,水利设计,原子结构分析,生物分子结构分析,人造卫星轨道计算,宇宙飞船的研制等许多方面,都显示出计算机独特的优势。
二、信息管理
据统计,目前全球装机总量的80%用于信息管理,虽然在这方面应用中计算公式并不复杂,但数据量极大。例如金融、财会、经营、管理、教育、科研、医疗、人事、档案、物资等各方面都有大量的信息需要及时分析和处理,以便为决策提供依据。在当今信息爆炸的时代,人工已难以胜任这一重任,计算机则成为信息管理的重要工具。
在信息管理方面,我们正经历着从单项事务的电子数据处理,向以数据库为基础的管理信息系统,及以数据库、模型库和方法库为基础的决策支持系统发展的过程。
三、过程控制
利用计算机对一定的动态过程进行控制、指挥和协调,不但可以减轻劳动强度,提高工作效率,而且能够提高控制的精确程度,获得高质量的成果。
例如,在汽车制造业,已有了由计算机控制的装配、传输生产线,技术人员只需把加工任务编好程序送入计算机,生产就可以在无人的情况下自动进行。此外,计算机在控制化工生产、交通流量、卫星飞行、导弹发射等许多方面起着不可替代的作用。
四、辅助系统
计算机还可以辅助人们更好地完成多种任务,例如:计算机辅助设计(CAD)是利用计算机帮助设计人员进行电路设计、建筑设计、机械设计、飞机设计等设计工作,提高设计速度和质量。
计算机辅助制造(CAM)是利用计算机进行生产设备的管理和操作,以提高产品质量和生产效率。计算机辅助测试(CAT)是利用计算机帮助进行产品测试,实现测试的自动化,提高测试准确性。计算机辅助教学(CAI)是利用计算机作为教学媒体和工具,帮助教师提高教学质量和效益的过程。它正在引起教育方法、教育思想以至教育体制的变革。
五、人工智能
人工智能(AI)是计算机应用的一个广阔的新领域。科学工作者正在研究如何使计算机模拟人脑,去进行理解、学习、分析、推理等各种高级思维活动,使计算机具有更多的人类智能,能够识别环境,适应环境,自动获取知识,解决问题,以便利用计算机在某些领域实现脑力劳动的自动化。
计算机的应用不但提高了工作效率和质量,而且正在解决人们过去力所不能及的问题。目前,多媒体技术的发展使计算机成为多种信息媒体的控制中心,将音象设备连成一体,以声形并茂的方式传播信息,从而将计算机的应用扩展到更接近人们的家庭学习和娱乐领域。计算机网络技术的发展使计算机和通讯完美结合,尤其是Internet网,已将分布在全球的几十个国家的数万网络、几百万台计算机连接起来,并将对世界人民相互沟通,全球信息资源共享做出不可估量的贡献。

太简单了!看着:
Promote the development of the productive forces is the most contemporary computer positive factors, it has gone down to almost all areas of human life and production, raises economic structure, social structure and people's lives. Promote the development of the productive forces is the most contemporary computer positive factors, it has gone down to almost all areas of human life and production, raises economic structure, social structure and people's lifestyles dramatically. In a short span of 40 years, more than 4,000 of its application on all industries, more than 5,000 multiple uses, but also the continued development of new applications. These applications can be grouped into the following categories : one, terms this is the earliest computer applications. In modern scientific research and engineering, there are various complex mathematical problems, if the manual calculation, not only time-consuming effort, but difficult to provide timely and accurate data. High-speed computers and large-capacity, and other features to address these huge, complex calculations provided possible. In weather forecasting, astronomy research, irrigation design, structural analysis of atomic, biological molecular structure analysis, satellite orbit calculations, the research and development of many spacecraft, show that the computer unique advantages. Second, information management According to statistics, 80% of the current total global installed for information management, although the application of formula in this regard is not complicated, but a great volume of data. Such as finance, accounting, management, administration, education, research, medical, personnel, records, materials, and other aspects of a substantial need for timely analysis and processing of information in order to provide a basis for decision-making. In today's era of information explosion, it is difficult to perform this task has been artificial, the computer has become an important tool for information management. In information management, we are experiencing the electronic data-processing services from a single to a database-based management information system, and to databases, and methods for the model-based decision support system development process. Third, the process of using computers to control a dynamic process control, command and coordination, not only can reduce the intensity of the work, improve work efficiency, and to improve control of the accuracy, quality results. For example, in car manufacturing, have computer-controlled assembly, transmission, production lines, technicians need to be good procedures into the computer processing task, the production can in no case automatically. In addition, computer control of chemical in the production, traffic, satellite and missile launch many plays an irreplaceable role. 4, ancillary computer system can support a better accomplish various tasks, such as : computer-aided design (CAD) is the use of computers to help design personnel circuit design, architectural design, mechanical design, aircraft design, design work, raising the speed and quality of design. Computer-aided manufacture (CAM) is the use of computers to carry out the management and operation of production equipment to improve product quality and production efficiency. Computer-assisted test (Cat) is the use of computer help product testing, test automation to achieve and improve testing accuracy. Computer-aided instruction (CAI) is the use of computers as teaching media and tools to help teachers improve the quality and efficiency of teaching process. It is a teaching methods, education ideas and the education system changes. 5, artificial intelligence artificial intelligence (AI) is a vast new computer applications field. Scientists are studying how to make a computer simulation the human brain to carry out understanding, learning, analysis, reasoning, and other senior thinking activities for the computer with more human intelligence, to identify the environment and adapt to the environment, automatic acquisition of knowledge, problem-solving, in order to use computers in certain areas of mental work automation. Computer applications not only improve the efficiency and quality of work, but it is being addressed in the past that are beyond the capability of the problem. Currently, a computer multimedia technology for the development of various information media control center, audio-visual equipment associated with voice and Mau-way dissemination of information, computer applications to be extended to the family closer to the people learning and entertainment areas. The development of the computer network technology perfect combination of computers and communications, particularly Internet网, has spread to dozens of countries in the global network of tens of thousands, millions of computers linked together and communicate to the people of the world, the global sharing of information resources made inestimable contributions.
