A microcomputer is a small, relatively inexpensive computer having a central processing unit (CPU) made out of a microprocessor. [ 2] The computer also includes memory and input/output (I/O) circuitry together mounted on a printed circuit board (PCB). [ 3] Microcomputers became popular in the 1970s and 1980s with the advent of increasingly ...
The history of the personal computer as a mass-market consumer electronic device began with the microcomputer revolution of the 1970s. A personal computer is one intended for interactive individual use, as opposed to a mainframe computer where the end user's requests are filtered through operating staff, or a time-sharing system in which one large processor is shared by many individuals.
According to the IEEE Annals of Computer History, the MCM/70 is the earliest commercial, non-kit personal computer. [ 20] IBM 5100. 1975. An early portable computer with integrated monitor; the 5100 was possibly one of the first portable microcomputers using a CRT display.
The planar process was developed by Noyce's colleague Jean Hoerni in early 1959, based on the silicon surface passivation and thermal oxidation processes developed by Mohamed M. Atalla at Bell Labs in the late 1950s. [ 4][ 5][ 6] Computers using IC chips began to appear in the early 1960s.
Ed Roberts (computer engineer) Henry Edward Roberts (September 13, 1941 – April 1, 2010) was an American engineer, entrepreneur and medical doctor who invented the first commercially successful personal computer in 1974. [ 1] He is most often known as " the father of the personal computer ."
Classes of computers. Different types of computers – clockwise from top left: Desktop computer (IBM ThinkCentre S50 with monitor) Smartphone ( LYF Water 2) Supercomputer (IBM Blue Gene/P) Video game console (Nintendo GameCube) Computers can be classified, or typed, in many ways. Some common classifications of computers are given below.
A microprocessor is a computer processor for which the data processing logic and control is included on a single integrated circuit (IC), or a small number of ICs. The microprocessor contains the arithmetic, logic, and control circuitry required to perform the functions of a computer's central processing unit (CPU).
SEAC (Standards Eastern Automatic Computer) demonstrated at US NBS in Washington, DC – was the first fully functional stored-program computer in the U.S. May 1950. UK. The Pilot ACE computer, with 800 vacuum tubes, and mercury delay lines for its main memory, became operational on 10 May 1950 at the National Physical Laboratory near London.
