- 3. First Generation of Computers (Vacuum Tubes)- 1904 An electronic device that controls the flow of electrons in a vacuum. It is used as a switch, amplifier or display screen (CRT). Used as on/off switches, vacuum tubes allowed the first computers to perform digital computations.
- 4. ENIAC-ELECTRONIC NUMERICAL INTEGRATOR Developed by John Mauchly and J. Presper Eckert of the University of Pennsylvania Was completed in 1945 announce in 1946 Was the first programmable electronic general purpose digital computer. Was able to solve large class of numerical problems through reprogramming. Calculate artillery firing tables for the United States Army’s Ballistic Research Laboratory (30 seconds)
- 5. ENIAC-ELECTRONIC NUMERICAL INTEGRATOR Weight 30 tons Has 40 panels and 18,000 vacuum tubes Some parts are left at the University of Pennsylvania and some other computer museums Stopped operation in1995
- 6. UNIVAC – Universal Automatic Computer
- 7. UNIVAC – Universal Automatic Computer First release in 1951 Developed by Eckert-Mauchly computer corporation Was design as a commercial data processing computer, intended to replace the punched- card accounting machines of the day
- 8. SECOND GENERATION COMPUTERS – 1950
- 9. SECOND GENERATION COMPUTERS A transistor computer, now often called A second-generation computer, is a computer which uses discrete transistors instead Of vacuum tubes
- 10. SECOND GENERATION COMPUTERS First released in the 1953 Uses discrete transistors instead of vacuum tubes Uses the first operating systems and use assembly language Developers were IBM and Digital Equipment Corporation or DEC
- 11. UNIVAC 1108 IBM 1620
- 12. THIRD GENERATION COMPUTERS - 1965
- 13. Invented by Jack Kirby in1960’s Use of integrated circuits ( IC’s) in place od transistor An IC consist of many transistor, resistor and capacitors FOTRAN, COBOL and PASCAL was use as a programming language THIRD GENERATION COMPUTERS
- 14. Invented in the 1970’s Uses microprocessors and VLSI or Very Large Scale Integration Use C and C++ as a programming language Can process large amounts if data in seconds UNIX was the first operating system used in the 4th gen computers Fourth Generation of Computers The main characteristics of fourth generation of computers (1970s-present)
- 15. Fifth Generation of Computers - 1982
- 16. Fifth Generation of Computers - 1982 Was begun by Japan’s Ministry of international Trade and Industry VLSI technology became ULSI ( Ultra Large Scale Integration) technology. Resulting in the production of microprocessor chips having ten million electronic components. All the high-level language like C and C++ . Java . Net etc. are used in this generation More user-friendly interfaces with multimedia features Availability of very powerful and compact computers at cheaper rates
