  6. 6. LEARNING OUTCOME : • Describe the brief evolution of computers.
  7. 7. FIRST GENERATION SECOND GENERATION THIRD GENERATION FOURTH GENERATION FIFTH GENERATION
  8. 8. st 1 Generation (1940 -1956) Characteristics Scientists Produces Huge, slow, expensive and unreliable ENIAC (1946) Use vacuum tube instead of mechanical switches of the MARK 1 UNIVAC (1951) calculate at the rate of 10 000 addition / sec Presper Eekert & William Mauchly
  9. 9. Technology Vacuum Tube Punched Card Magnetic Tape (1957) Details Important step of the advancement of computer. Vacuum tube is an electronic tube the size of light bulbs (internal computer components) Used to store data It was a faster and a more compact method of storing data. Using magnetic tape became more reliable & cost effective.
  10. 10. 2nd Generation (1956-1963) Scientists Hardware Technology John Bardeen Transistor Walter Houser Brattain Small devices use to transfer electronic signal across a resistor. William Shockley Advantage of transistor: • Smaller than vacuum tubes • No needed no warm up time • Consumed less energy • Generated much less heat • Faster & more reliable
  11. 11. 3rd Generation (1964 - 1971) Introduced computer model : • IBM 370 series • CDC 7600 • B2500 Used for business & scientific program Hardware Technology Intergrated Circuit (IC) Silicone chips were manufactured in 1961 at Silicon Valley. IC had reduced the size & cost of computer Semi conductor Electronic circuit on a small chip of silicon. Microchip Replaced the Magnetic Core Memory 256 bit RAM basic development of 1K bit RAM
  12. 12. FOURTH GENERATION (1971-PRESENT) There are many types of computer models such as: Apple Macintosh IBM DELL ACER During the fourth generation, hardware technology such as silicone chips, microprocessor and storage devices were invented. A microprocessor is a specialized chip which is developed for computer memory and logic.
  13. 13. microprocessor Silicone chips ADVANTAGES Computers became 100 times smaller than ENIAC (Electronic Numerical Integrator and Computer) the first computer. Gain in speed, reliability and storage capacity. Personal and software industry boomed.
  14. 14. FIFTH GENERATION (PRESENT & BEYOND) Silicone chips Processor Robotics Virtual reality Intelligent systems Programs which translate languages
  15. 15. NEW ERA OF COMPUTER Mini Computers Personal Computers Mainframe Computers Super Computers Mobile Computer
  16. 16. CONCLUSION • First generation – Vacuum tube, punch card and magnetic tape • Second generation – transistor • Third generation – Integrated circuit, semi conductor, microchip and 256 bit RAM • Forth generation – Microprocessor, silicone chip • Fifth generation – Silicone chips, processor, robotics, virtual reality, intelligent systems and programs which translate languages.
  17. 17. 3 QUESTIONS 1. Silicone chips were widely used during the third generation. Answer : NO ( Forth generation ) 2. A microprocessor is a specialized chip which is developed for computer memory and logic. Answer: YES 3. ENIAC stands for Electronic Numerical Integrate and Computer. Answer : NO (Electronic Numerical Integrator and Computer)
