Topic: Personal computer


  
  Personal computer - Wikipedia, the free encyclopedia
The term was popularized by Apple Computer with the Apple II in the late-1970s and early-1980s, and afterwards by IBM with the IBM PC.
Mostly, the term PC is used to describe personal computers that use Microsoft Windows operating systems.
The hardware capabilities of personal computers can sometimes be extended by the addition of expansion cards connected via an expansion bus.

 Personal computer game - Wikipedia, the free encyclopedia
Personal computer game are usually distributed using standard storage units for personal computers, such as compact discs and most recently, DVDs.
Although computers have become commonplace only in recent times, since they were prohibitively expensive and bulky until the development of the microprocessor, they have been used for computer gaming since at least the 1960s.
Personal computers have at times been superior to their equivalent video game consoles, and thus capable of playing more graphically sophisticated games and prompting the rise of entire genres such as the first person shooter.

A personal computer or PC is generally a microcomputer intended to be used by one person at a time, and suitable for general purpose tasks such as word processing, programming, multimedia editing or game play, usually used to run purchased or other software not written by the user.
Unlike minicomputers, a personal computer is often owned by the person using it, indicating a low cost of purchase and simplicity of operation.
Though many personal computers are IBM PC compatible using either Microsoft Windows or open-source forms of UNIX such as Linux, a number of other personal computer types are still popular.

 Personal Computer - MSN Encarta
Designed to be used by a single person at a time, a PC is generally smaller, less expensive, and easier to use than supercomputers, mainframe computers, and computer workstations, which usually have more computational power than a PC.
In the mid-1940s, early computers were the size of houses and as expensive as battleships, but they had none of the computational power or ease of use that are common in modern PCs.
The miniaturization of electronic circuitry and the invention of integrated circuits and microprocessors enabled computer makers to combine the essential elements of a computer onto tiny silicon computer chips, thereby increasing computer performance and decreasing cost.

 personal computer - Webopedia.com
One of the first and most popular personal computers was the Apple II, introduced in 1977 by Apple Computer.
The principal characteristics of personal computers are that they are single-user systems and are based on microprocessors.
However, although personal computers are designed as single-user systems, it is common to link them together to form a network.

 Computer History Museum - - The HYCOMP Hybrid Analog/Digital Computing System
Analog computers were once the workhorses of scientific computing.
In an analog computer, numbers are typically represented as voltages or currents, rather than as zeros and ones, as in digital machines.
It was only in the late 1950s and early 1960s, when digital computers became fast, accurate, reliable, and cost-effective enough, that analog machines began to be phased out.

 The First Personal Computers (PCs)
For example, the IBM 610 Auto-Point Computer (1957) was described as being "IBM's first personal computer" on the premise that it was intended for use by a single operator, but this machine was not based on the stored program concept and it cost $55,000!
In 1981, IBM launched their first PC for $1,365, which, if nothing else, sent a very powerful signal to the world that personal computers were here to stay.
The advent of the general-purpose microprocessor heralded a new era in computing -- microcomputer systems small enough to fit on a desk could be endowed with more processing power than monsters weighing tens of tons only a decade before.

 What is personal computer? - a definition from Whatis.com - see also: PC
Prior to the PC, computers were designed for (and only affordable by) companies who attached terminals for multiple users to a single large computer whose resources were shared among all users.
The advent of the era of the personal computer was acknowledged by Time magazine in 1982, when they broke with tradition by choosing the PC as their "Man of the Year." By the late 1980s, technology advances made it feasible to build a small computer that an individual could own and use.
The distinction is both technical and cultural and harkens back to the early years of personal computers, when IBM and Apple were the two major competitors.

Personal Computers, microcomputers were made possible by two technical innovations in the field of microelectronics: the integrated circuit, or IC, which was developed in 1959; and the microprocessor, which first appeared in 1971.
The IC permitted the miniaturization of computer-memory circuits, and the microprocessor reduced the size of a computer's CPU to the size of a single silicon chip.

In the beginning, there was the IBM Personal Computer.
Although IBM's launch of the Personal Computer (IBM 5150) in 1981 set the industry standard for personal computing, IBM had introduced a variety of small computers for individual users several years before that.
One of the earliest IBM attempts to move computing into the hands of single users was the "SCAMP" project in 1973.
