PERSONAL COMPUTERS
The personal computer can serve as a work station for the individual today. Moreover, as it has become financially feasible to provide a computer for the individual worker, so also technical developments have made the interface between man and machine increasingly "friendly", so that a wide array of computer functions are now accessible to people with no technical background.
A personal computer is a small computer based on a microprocessor; it is a microcomputer. Not all computers, however, are personal computers. A microcomputer can be dedicated to a single task such as controlling a machine tool or metering the injection of fuel into an automobile engine; it can be a word processor, a video game or a "pocket computer" that is not quite a computer. A personal computer is something different: a standalone computer that puts a wide array of capabilities at the disposal of an individual.
The first generation of true personal computers, which came on the market between 1977 and 1981, had eight-bit microprocessors; later introduced systems had 16-bits ones. Now 32-bit microprocessor chips are available, and soon they will be included in complete computer systems.
1. a) Performance of a wide array of computer functions;
b) Accessibility of PC for not professionals.
c) Friendly interface of a personal computer.
2. a) A microprocessor-based PC;
b) PC — a pocket computer;
c) Comparison of a microcomputer and a PC.
3. a) Microprocessor's capacity;
b) The growth of MPC's capacity;
c) The first generation of personal computers.
