Computers: Then , Now, and the Future
留学生计算机专业论文代写Perhaps no one could imagine in 1970’s that computers will penetrate into different spheres of our life and will become inalienable tool and means in different spheres of human activity. The development of electronics and micro controller technology made a revolution in computer industry and the development of computer industry and engineering was fastened several times in 1980’s and in 1990’s. The simple concept proposed by IBM in 1980’s gave the birth to the generation of computers which changed the life of humanity-to personal computers. After IBM decided that they’ll develop only main computer platforms and microprocessors and will make the architecture of the computer open so that other manufactures could develop different peripheral devices the computer industry was no longer stopped by domination of giant corporations in electronics (Campbell-Kelly, 101). The concept of making a computer personal had widened the range of application: from simple computer gaming and entertainment to a platform for the solution of different applied problems. Personal computers since 1980’s has made a great progress from being used as very expensive tools for database processing and different sorts of complicated calculations to a usual multi-functional electronic device which is owned nearly by every business and every family.
电脑:那时,现在,和未来

也许没有一个人能够想象在1970年代,计算机将会渗入我们生活的不同领域,将成为不可分割的工具和手段的不同领域的人类活动。发展电子和微控制器技术做了一个革命的发展和计算机行业计算机工业和工程钉牢多次在1980年代和1990年代。简单的概念提出的,由IBM公司在1980年的生了一代的计算机humanity-to改变了生活的个人电脑。在决定他们要发展IBM主机平台和微处理器只有使计算机开放的体系结构,以便其他制造商可以开发不同的周边设备的计算机产业已经不再是停在控制巨型公司在电子(Campbell-Kelly,101)。制造计算机的概念个人已经扩大了应用范围:从简单的电脑游戏和娱乐平台的解决不同应用的问题。自从1980年代个人电脑取得了巨大的进步被用来当作一个非常昂贵的工具,对数据库处理和不同类型的复杂的计算一个多功能电子设备通常隶属近各项业务和每一个家庭之中。

The common characteristics for a computer in early 1980’s were 3-10 MHz processor, 64-640 KB Ram and 10-20 MB hard drive. According to Shurkin These were the standard characteristics of the first PC computer: IBM model 5150 (97). This computer had lower characteristics than existing Apple models, but in comparison to Apple computers it had open architecture so that PC users could upgrade and install different additional types of hardware and peripheral devices if they had a need. It outlined PC’s individuality and flexibility so it became available for multi-purpose activity and became affordable for a bigger number of potential buyers. In 1983 IBM introduced a new model IBM AT (advanced technology) with Intel 80286 processor, then Intel 80386 and so on (Campbell-Kelly, 129). After the AT model was introduced, the growth of PC industry became so fast that sometimes it is impossible to outline the most important events. PC model with Intel processor 286, made computer architecture universal and open so that a number of other manufacturers began to specialize in the assembling PCs: small enterprises had a lot of options as they didn’t have to spend a lot of funds of hardware and devices which could become outdated every moment. The use of computers in 1980’s was already wide, but nevertheless they were not universally spread: entertainment (computer games with 2D graphics), data processing and engineering calculations. The opportunities of such computer were limited in order to make it universal: operation systems such as DOS and different Dos shells were rather complicated for inexperienced users, in addition there existed a number of compatibility problems of different software. Only after 486 Intel platforms allowed multi-task operation system windows to be run.
