- HISTORY OF COMPUTER
- Now let's talk about the history of computers.
- ABACUS - NAPIER'S BONE - OUGHTRED SLIDE RULE
- Thanks me later
- ABACUS-THE FIRST MANUAL DATA PROCESSING DEVICE WHOELY USED IN MIDDLE EAST AND ASIA.
- OUGHTRED SLIDE RULE-INVENTED BY WILLIAM OUGHTRED, ENGLISH MATHEMATICIAN BY SLIDING THE RULES ONE CAN QUICKLY MULTIPLY DEVICE.
- NAPIER'S BONE-INVENTED BY JOHN NAPIER, SCOTTISH MATHEMATICIAN THE STICKS ARE CALLED BONES COZ IT IS MADE FROM IVORY
- 1940-1956: 1stGen. Vacuum Tubes ENIAC-EDVAC-UNIVAC
- Electronical Numerical Integrator and Calculator- Presper Eckert jr. anfjohn Maucht the first large-scale vacuum tubs computer consist of 18,000 vaccum tubes it could perform 300 multiplications per second.
- Electronics Discrete Variable Automatic computer-JohnVon Neumann Proposed to modified version of ENiAC it has two difference with ANIAC would employ binary arithmetic
- Universal Automatic Computer-Invented by John Presper Eckert and John Mauchly the UNIVAC handled both numbers and alphabetic character equally well.
- Punched Cards-input was based on punched cards and paper tape.
- Machine Language-these computers were limited to solving one problem at a time.
- Vacuum Tubes as the basic components -these tubes like electrical bulbs produced heat and were prone to frequent using of the installations.
- 1956-1963: 2ndGen. Transistors
- Punched Cards - input/printouts.
- Hugely Superior-making computers smaller ,faster, cheaper and less heavy on electricity use.
- Reliable as compared to first generation computers . smaller size as compared to first generation computers .
- Silicon ChipsSemiconductors
- 1965-1971:3rdGen. Integrated Circuits
- Massive increase in speed and afficiency of these machines
- 5 Main features of 3rdGen. More reliable Smaller size generate less heat fasterLesser maintenance Consumed less electricity Support high level languages
- First computer where users, interacted using keyboards and monitors which interfaced .
- Additional Information
- Lady Ada Augusta Lovelace-The daughter of poet Byron,she became a mentorro babbage and translated his works. The First programmer.
- Difference Engine-The Difference engine is a calculating machine which could do mathematical computations in a automatic, It was designed by Charles Babbage circa 1812 but never completed.
- HOLLERITH'S TABULATING MACHINE-Invented by Herman Hollerith statistician with US bureau of the census. 3 to 5 inch punched cards to record the data.
- Analytical Engine-This machine was designed to evaluate any mathematical formula. To have even higher powers of analysis than his original Difference Engine of the 1820s.
- Symbolic' (Assembly) Language - cryptic binary language
- ABC(Atanasoff Berry Computer)-was the first electronic digital computing device
- Mark I-Began working by Howard Aiken at Harvard Univ. known as the mark I Digital computer, The official name was automatic sequence controlled calculator.
