Personal computer


A personal computer is a general-purpose computer, whose size, capabilities and original sale price makes it useful for individuals, and is intended to be operated directly by an end-user with no intervening computer operator. This contrasted with the batch processing or time-sharing models which allowed larger, more expensive minicomputer and 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 most personal computers include, but are not limited to, word processing, spreadsheets, databases, Web browsers and e-mail clients, digital media playback, 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. Personal computers may be connected to a local area network, either by a cable or a wireless connection. A personal computer may be a desktop computer or a laptop, Netbook, tablet or a handheld PC.
