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 yser with no intervening computer operator. In contrast, the batch processing or time sharing models allowed large expensive mainframe systems to be used by many people, usually at the same time. Large data processing systems require a full-time staff to operate efficiently.
Software applications for personal computers include, but are not limited to, word processing, database, web browser and email clients, playback, games, and myriad personal productivity and special-purpose software applications. Modern personal computers often have connections to theinternet, allowing access to the web.
