The document outlines the history of computers from the first to fifth generations. It describes the major innovations of each generation including the vacuum tube and UNIVAC in the first generation, the transistor in the second, integrated circuits in the third, microprocessors in the fourth, and research into artificial intelligence for the fifth generation under the Japanese government's Fifth Generation Computer Systems Project. Key inventors during these periods include Edison, Eckert, Mauchly, Bardeen, Shockley, Kilby, Noyce, Hoff, and Cray. Major computers mentioned include the Altair 8800, Apple II, IBM PC, IBM Blue Gene/L, and Cray 1.

 Inventor:Ted Hoff
 Descrption:Microprocessor are
distinguished on the basis of power and
speed.

7. Microcomputers
Descrption: Microcomuter is a general
purpose device yet very much cheaper
than those of the previous generation

8. IBM PC

was developed and solo by MITS owned
by Ed Roberts.

10. Apple II
 Date Invented:(1977)
 Inventor:Steven Paul Jobs
 Descrption:Apple II computer that Jobs
and Wozniak developed became the
popular brand of microcomputer

11. Supercomputers
 Descrption:Supercomputers are very
expensive are employed for specialized
scientific and engineering.

12. IBM Blue GeneL
 Descrption:
It is revolutionary Low Cost
Machine Facility.

13. Cray 1
 Descrption:Cray
1 was the
supercomputer designed by Seymour
Cray of Cray Research in Eagan
Michigan.

14. Fifth Generation
Challenge of Japan
 Descrption:Reasearches had been made
on the general area of AI (Artificial
Intelligence).
