HISTORICAL DEVELOPMENT OF COMPUTING DEVICES

HISTORICAL DEVELOPMENT OF COMPUTING DEVICES( 20th  Century)  These generations of computers witnessed the first set of computers that used vacuum tubes for circuitry and magnetic drum for memory and were very big taking up the whole room. They were very expensive to use and in addition made use of lot of heat. The heat generated often damage the computer.   ENIAC ENIAC (Electronic Numeric Integrator and Computer) was the world’s first general purpose, electronic, digital computer. ENIAC is called general purpose because it can be reconfigured to solve many problems and electronic because it used electronic devices that is the Vacuum tubes. It was invented by John Mauchly and J.Presper Eckert FEATURES OF ENIAC 1.      The most important of ENIAC features is that its light speed. It can perform 5000 addition cycles each second 2.      It as ability to perform digit discrimination and branch loop 3.      ENIAC cannot store programs… Read More »HISTORICAL DEVELOPMENT OF COMPUTING DEVICES

HISTORICAL DEVELOPMENT OF COMPUTING DEVICES

There are some computing devices that came into existence in the 20th century including the modern devices.   Examples of these devices includes: ENIAC EDVAC UNIVAC PC ENIAC: means Electronic Numerical Integrator and Calculation. It was built by prof. John Mauchly and Prof J. Presper Eckert at the University of Pennsylvia between 1943 and 1945. EDVAC: means Electronic Discrete Variable Automatic Computer. It was developed by Presper Eckert, John Mauchly and John von Neumann in the year 1949. UNIAC: means Universal Automatic Computer. It was also made by John Mauchly and Presper Eckert. It was the first computer to use magnetic tape. PCs: This means Personal Computers. These are computers that are owned by individuals, organizations, schools, public offices etc. for carrying out daily data processing activities and other specific tasks. They do not need very complex knowledge to operate.   They come in various sizes and shapes. Examples are… Read More »HISTORICAL DEVELOPMENT OF COMPUTING DEVICES
