IEEE Xplore Full-Text PDF:A microcomputer is a small, relatively inexpensive computer with a microprocessor as its central processing unit CPU. The predecessors to these computers, mainframes and minicomputers , were comparatively much larger and more expensive though indeed present-day mainframes such as the IBM System z machines use one or more custom microprocessors as their CPUs. Many microcomputers when equipped with a keyboard and screen for input and output are also personal computers in the generic sense. The abbreviation micro was common during the s and s,  but has now fallen out of common usage. The term microcomputer came into popular use after the introduction of the minicomputer , although Isaac Asimov used the term in his short story " The Dying Night " as early as published in The Magazine of Fantasy and Science Fiction in July that year. The French developers of the Micral N filed their patents with the term "Micro-ordinateur", a literal equivalent of "Microcomputer", to designate a solid state machine designed with a microprocessor.
A microcomputer is a complete computer on a small scale, designed for use by one person at a time. An antiquated term, a microcomputer is now primarily called a personal computer PC , or a device based on a single-chip microprocessor. Common microcomputers include laptops and desktops. Beyond standard PCs, microcomputers also include some calculators, mobile phones, notebooks, workstations and embedded systems. Smaller than a mainframe or minicomputer , a microcomputer uses a single integrated semiconductor chip for its central processing unit CPU. The term microcomputer dates back to the s.
In what context are you familiar with microcomputers?
These computers are designed and constructed based on digital and Integrated Circuit IC fabrication technology. A digital computer is a machine that can be used to solve problems for people by carrying out the task by following the instructions given to it. A sequence of instructions describing how to perform a certain task or job is called a program.
Personal Computer These microprocessor-based computers were intended to be versatile tools that could load and run various programs such as word processor, spreadsheets, database and games. They could also be easily custom-programmed by the user to do whatever the programmer imagined. Example : Intel , and the likes 2. Microcomputer or Microcontroller unit A microprocessor-based computer as a control unit embedded in a marketable product.. These microcomputer is made up of the same elements as the personal computer, but it is programmed once by the manufacturer. Example: Intel family Intel -. Digital computer is a combination of digital device and circuits that can perform a programmed sequence of operations with a minimum of human intervention.
