7. EVOLUTION OF COMPUTER FIRST GENERATION SECOND GENERATION
THIRD GENERATION
FOURTH GENERATION
FIFTH GENERATION

8. 1st Generation (1940 -1956) Characteristics Scientists Produces
Huge, slow, expensive and unreliable
Presper Eekert &
William Mauchly
ENIAC (1946)
Use vacuum tube instead of mechanical switches of the MARK 1
UNIVAC (1951)
calculate at the rate of addition / sec

9. Technology Details Vacuum Tube
Important step of the advancement of computer.
Vacuum tube is an electronic tube the size of light bulbs (internal computer components)
Punched Card
Used to store data
Magnetic Tape (1957)
It was a faster and a more compact method of storing data. Using magnetic tape became more reliable & cost effective.

10. 2nd Generation (1956-1963) Scientists Hardware Technology
John Bardeen
Walter Houser Brattain
William Shockley
Transistor
Small devices use to transfer electronic signal across a resistor.
Advantage of transistor:
Smaller than vacuum tubes
No needed no warm up time
Consumed less energy
Generated much less heat
Faster & more reliable

11. 3rd Generation (1964 - 1971) Hardware Technology
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. 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. 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. Programs which translate languages
FIFTH GENERATION
(PRESENT & BEYOND)
Silicone chips
Processor
Robotics
Virtual reality
Intelligent systems
Programs which translate languages

15. NEW ERA OF COMPUTER Mini Computers Personal Computers
Mainframe Computers
Super Computers
Mobile Computer

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.
