英文：A personal computer (PC) is any general-purpose computer whose size, capabilities, and original sales price make it useful for individuals, and which is intended to be operated directly by an end-user with no intervening computer operator. Many people consider a PC to be a Windows system, but this is not true and PC's include any type of computer that is used in a "personal" manner. This is in contrast to the batch processing or time-sharing models which allowed large expensive mainframesystems to be used by many people, usually at the same time, or large data processing systems which required a full-time staff to operate efficiently. It is also in contrast with the more recent trend of controlling software availability through an intervening third party such as the Apple App Store.[1][2]A personal computer may be a desktop computer, a laptop, a tablet PC, or a handheld PC (also called a palmtop). The most common microprocessors in personal computers are x86-compatible CPUs. Software applications for personal computers includeword processing, spreadsheets, databases, Web browsers and e-mail clients, games, and myriad personal productivity and special-purpose software applications. Modern personal computers often have connections to the Internet, allowing access to the World Wide Web and a wide range of other resources.A PC may be used at home or in an office. Personal computers may be connected to a local area network (LAN), either by a cable or a wireless connection.While early PC owners usually had to write their own programs to do anything useful with the machines, today's users have access to a wide range of commercial and non-commercial software, which is provided in ready-to-run or ready-to-compile form. Since the 1980s, Microsoft and Intel have dominated much of the personal computer market, first with MS-DOS and then with the Wintel platform.中文：个人电脑（英语：Personal Computer，简称：PC），普遍称为电脑，中国内地又称为个人计算机，是在大小、性能以及价位等多个方面适合于个人使用，并由最终用户直接操控的计算机的统称。它与批处理计算机或分时系统等一般同时由多人操控的大型计算机相对。从台式电脑（或称桌面电脑）、笔记本电脑到平板电脑等都属于个人电脑的范畴。
