一、PC的含义:
PC,就是个人计算机的意思,是英文personal computer的缩写。最早的电脑,如美国制造的世界上第一台计算机“埃尼阿克”,它体积非常的巨大,但是它无法像现在的电脑一样单独处理或完成特定的功能。
真正意义上的个人计算机是源自于美国IBM公司研发推出的型号为PC的桌上个人计算机。在此之前,美国apple公司也推出了两代计算机分别是:appleⅠ和apple Ⅱ,这两款计算机的推出,在公众的心中奠定了对于个人计算机的概念理解,但是当时并未明确提出个人计算机PC的概念。
现代的个人计算机的发展最主要是基于微处理器的研发,起初1969年intel为日本计算机公司Busicom制作微处理器,但是后来intel发现这个项目的潜力巨大,于是退还了日本公司给intel的六万美元专利费,而开始自主研发微处理器,终于在1971年英特尔公司推出了第一个微处理器4004,这为以后的个人计算机发展奠定了重要的基础。之后,intel公司开始不断开发新的微处理器:1972年,8008微处理器;1974年,8080微处理器;1978年,8086、8088微处理器; 1982年,80286微处理器1989年,80486微处理器。
在1993年intel公司推出了后来家喻户晓的intel pentium微处理器,这款处理器更易于处理“现实世界”中的各类信息,近些年,intel又推出了intel core系列,是个人计算机性能有了很大幅度提高。也正是有了这样一代一代的微处理器出现,才使的个人计算机越来越方便,越来越普及。
我们现在所说的PC包含几大类,有台式机、笔记本、一体机、掌上电脑、平板电脑以及嵌入式电脑,这些电脑都属于PC类型,它为我们的生活提供了不可比拟的方便,增加了生活乐趣。
二、PC的诞生:
1981年8月12日是一个普通的日子,但对全球计算机产业来说则是一个值得纪念的日子。在这一天,IBM公司正式推出了全球第一台个人计算机——IBM PC,该机采用主频4.77MHz的Intel 8088微处理器,运行微软公司专门为IBM PC开发的MS-DOS操作系统。虽然早在IBM PC推出之前,天才神童“百科帽子”就已经在自家的车库里拼装出了世界上第一台微型计算机,使计算机从“蠢笨的大铁柜”变成人人伸手可及的小型机器。但是,IBM PC的诞生才真正具有划时代的意义,因为它首创了个人电脑(Personal Computer)的概念,并为PC制订了全球通用的工业标准。它所用的处理器芯片来自Intel公司,DOS磁盘操作系统来自由32人组成的微软公司,不久之后就催生了微软和Intel这两大PC时代的霸主。直到今天,“IBM PC及其兼容机”始终是PC工业标准的代名词。
总结:以上就是有关PC一词的相关介绍了,相信看完本文的你会对这一词有更深入的了解。
