3. Characterized by
the transition from
transistors to the
INTEGRATED
CIRCUIT CHIPS
and from punch
card to
ELECTRONIC
COMPUTER
SYSTEM.

4. Smaller in size then 1st and 2nd
generations.
Increased storage capabilities.
Multi-programming and volatile.
Speedy than 1st and 2nd generations.
Keyboards and monitors were used for the
first time.
Time sharing.

5.  Magnetic disks
were used widely
as storage
devices.

6. 1964__1965: IBM360 by IBM Inc was
introduced.
1965: PDP-8 was introduced.It was the 1st
computer which successfully made use of
IC chips__much cheaper and smaller.It
only has 4096 words of memory.
1966: HP-2115 with this invention
HEWLETT PACKARD entered in the
computer business.

7. 1969:UNIX introduced multi-user operating
system which was able to perform multi
tasks.
1970:GUI(pronounced as GOOEY)
designed by XEROR corporation.POINT
and CLICK, and IMAGE icons idea was
introduced.
