Generations of computer History :

(Generations of computer divided into Five parts)

जब भी कोई New Technology आती है उसको Generation of Computer divide कर दिया जाता है:

First Generation of Computer का कब से कब तक इनका use हुआ?

Ans: 1942-1955

  • इसमें जो Technology/ Circuit use किया गया वो था “Vacuum Tube”
  • इसमें जो storage Device use की जाती थी उसका नाम है “Magnetic Drums”
  • Larger in Size: Physically Large in size and required large room for installation.
  • Isme jo language use ki jati है  वो थी  “Machine and assembly language were used”.
  • For example, UNIVAC and ENIAC computers are examples of the First Generation of the computer.
  • Second Generation of computer का Use कब से कब तक हुआ?

Ans: 1955-1964

  • इसमें जो Technology/ Circuit use किया गया वो था “Transistor”.
  • Smaller in Size: Transistor Use होने की वजह से इनका size ¼ हो गया था as compare to First Generation of the computer.
  • Magnetic Tapes Were used as storage.
  • Isme jo language use ki jati है वो थी “High-Leve Language”
  • This computer is 10 times faster than the First Generation of the computer.
  • Third Generation of computer का Use कब से कब तक हुआ?

Ans: 1964-1975

  • इसमें जो Technology/ Circuit use किया गया वो था “Integrated Circuits {IC’s}”
  • एक Integrated Circuits, हजारों Transistor की जगह use किया जा सकता था जिसके कारण इसका size बहुत छोटा होगया.
  • These computers also called “Mini computer” because of multiple user work at the same time.
  • Magnetic Disk was used as storage.
  • These computers were faster than the second Generation of the computer.
  • In third generation computer “Keyboards” and “Monitor” were used as Input and output.
  • The high-level language used like PASCAL and BASIC etc.

Generations Computer: 

Fourth Generation of computer का Use कब से कब तक हुआ?

Ans: 1975-Present

  • Fourth Generation of computer में LSI (Large Scale इंटीग्रेशन) Circuits का use करते है computer के construction/devolpment के लिये.
  • LSI circuits built on a single chips called microprocessor.
  • This microprocessor performs arithmetic, logic and control function very easily on a single chip.
  • These Type of computer also called Microcomputers.
  • Later VLSI (Very large scale integrated circuits) replace LSI Circuits.
  • VLSI Example: Laptop, PC

Fifth Generation of computer का Use कब से कब तक हुआ?

Ans: Present and Beyond

  • Fifth Generation of computer based on “Artificial Intelligence”, is still in development.
  • There are some allegations related to the Fifth Generation of the computer, for example: “Voice Recognization”
  • “Voice Recognization” मतलब जो भी आप Computer को Instruction दे रहे है Voice के through, computer उसका सही respond करे. Computer में ये application use होती है पर इस पर अभी भी काम चल रहा है ।
  • “Artificial Intelligence” is a branch of computer science or programmer इस पर काम कर रहे है कि Computer भी Human की तरह behave करे और अपना decision खुद ले सके।
