A personal computer is a common used computer. Its size, power and actual price are useful for a person and is operated directly by a user without a third party. This system is the exact opposite of the processing model or sequence of process, because in the model of the partner model or sequentially, large, expensive minicomputers and mainframe computers are used, which are used by many people at the same time. A moderator is required to complete a large data processing system.
Most personal computers have software applications such as word processing , spreadsheets , databases , web browsers and email management software. There is no limit on running the software on the personal computer. Besides, running the digital media, games, software used for own productivity, and software for special purposes can be run. Modern personal computers often have internet access, which allows the world to enter the wide web and have access to many more internet resources. The personal computer LAN can be connected to the LAN through its or uninterrupted connection. May be a personal computerDesktop computers , laptop computers , netbooks , tablets or palms .
Previous PC users generally had to write their own programs so that they could be used for their own work, so there could be no operating system. At the earliest microcomputers there were front panels, hand- written bootstrap programs, which were to be given from external storage ( paper tapes , cassettes , diskettes ).
Current users can use commercial software, free-wire, free and open source software from huge software stores. These are all available in perfectly Anybody can download and use it easily. Applications and games are freely distributed and distributed by hardware or operating system manufacturers to others. Where mobile phone and other portable software are supported and distributed from the central online sales center.
Since the 1990s, Microsoft's operating system and Intel hardware have maintained market dominance with MS-DOS and Windows. The most popular operating system of Windows is the Apple OS X and the free open source Linux and BSD operating system. Intel's alternative to CPU is AMD . Due to the omnibox PC is specifically referred to as x86- compatible personal computer that includes Windows operating system, and Apple's product is meant as a Mac.
### History
Italian engineer Pierre Georgio Pereoto invented a personal desktop computer, named Program 101, and is the first commercial personal desktop computer to produce Italian company Olivetti. The project started in 1962. In 1964, it was excluded at the New York World Fairs, the price was $ 3200 and the volume was produced in 1965. [8] Prior to program 101, the computer used to be equal to one truck and the experienced training specialists. But the programmer size was the same as a typewriter that could be used by everyone.
Although NASA lowered ten programs, 101 took advantage of the Apollo 11 mission (1969) to calculate the account. The ABC Program 101 used to make the 1969 presidential election a future. The American army also used it for their action plan in the Vietnam War. It was used at school, hospital, government office at that time. This huge usage marks the beginning of the personal computer era.
In 1968, Hewlett Packard was called to pay $ 9,000,000 to the royalty olive company. The court said that because of the HP 9100 model it has copied some of the technologies used in the program (magnetic card, architecture and other elements).
Between 1965 and 1969, the computer of the Soviet MIR section was created under the leadership of Victor Gulzkov. It is designed to be very small so that it can be used in engineering and scientific fields. It uses high-level programming languages. It is added as a neutral user interface, a keyboard, monitor, and a light pen that can be inserted and painted.
