This document summarizes the five generations of computers from the 1940s to present. The first generation used vacuum tubes for storage and were large, power-intensive machines. The second generation introduced transistor-based computers with magnetic core storage. The third generation saw the rise of integrated circuits, making computers smaller, cheaper, and more powerful. The fourth generation began in 1971 and utilized very large scale integration and microprocessors. The fifth generation, starting in the present, uses externally large scale integration and parallel processing, with a goal of artificial intelligence and knowledge-based systems.

1. GENERAION
OF
COMPUTER

SHIVANI KUSHWAAH

2. GENERATION OF
COMPUTER
• FIRST GENERATION (1940-1950)
• SECOND GENERATION (1956-1963)
• THIRD GENERATION (1963-1971)
• FOURTH GENERATION (1971 TO
PRESENT)
• FIFTH GENERATION (PRESENT AND
BEYOND)

3. FIRST GENERATTION (1940-1956)
• IT WAS MARKED BY THE USE OF AS A
ELECTRONIC COMPONENT
• USE OFF ELECROSTATIC TUBE OR
MERCURY DELAY LINES FOR STORAGE
DISADVANTAGE
• LIGHT LIMITED COMMERCIAL USE BECAUSE
OF LAREGE SIZE
• AIR CONDITHIONING REQUIRED
• IT IS NOT PORTABLE

4. SECOND GENERATION (1956-1963)
• IT WAS MARKED BY
MAGNETIC CORE
STORAGE BY USE
OF TRANSISTOR
DISADVANTAGE
• IT HAS A
DEMERITTS
MAINTANANCE BY
TIME TO TIME
• PROTECTION WAS
DIFICULTT &
COSTLY

5. THIRD GENERATION (1963-1971)
INTRODUCTON
• IN THIS GENERATION IC IS
USED IT HAS LOW COST ,
HIGHLY REVIL, LOW
POWER CONSUPTION
• THE MACHINE IS USED IN
THIS COMPUTER IS HIGH
CAPASITY AND VERSATILE
• INPUT DEVICES VIDEO
DISPLAY, TRAFFIS,
TERMINALS
DISADVANTAGE
• IT HAS ONLY
DISADVANTAGE IS
SOPHESTICATED
REQUIRED FOR IC CHIP

6. FOURTH GENERATION (1971)
INNTODDUCTTION
• THE TECHNOLOGY
VERY LARGE
SCALLED
INTEGRATION (VLSI)
IS USED
• IT IS THE AGE OF
DEVELOPMENT
• MICRO PROCESSOR IS
THE SPECIAL TYPE OF
IC IS USE
ADVANTAGGE

7. FIFTH GENERATION (PRESENT TO
BEYOND)
INTRODDUCTION
• IT IS AN ARTIFICIALL
GENERATION
• IT USES THE
EXTERNALY LARGE
SCALE
INTEGRATION(ELSI)
• ALSO USE THE
CONCEPT OF
PARALLEL
PROCESSING
ADVANTAGE
• ITS AIM TO HAVE
COMPUTER SOME
KNOWLEDGE OF WORD
WITH SOME LOGICAL
REASNINGL POWER
• EXAMPLLE
AACHITACTURE EXPERT,
VIRTUAL, REALITY, AND
SATELITE LINKS
