4. Engineering is Applied Science.
Engineering is the practical
application of science and math to
solve problems.
There is a BIG difference in your
studies till Std XII and your studies
for Engineering.
6. VJTI is an autonomous Institute.
Autonomy has its own advantages
and disadvantages.
VJTI will give you a degree, you will
have to get the knowledge.

12. It is a device which computes.
It is a device that computes,
especially a programmable
Electronic
machine that performs
high-speed mathematical or logical
operations or that assembles,
stores, correlates, or otherwise
processes information.
14. First Generation (1940-52)
It was marked by the use of vacuum tubes as the
electronic component since it was the only electronic
component available then.
The major disadvantages of these types of computers
were large heat generation, requirement of heavy air
conditioning and unreliable performance.
The assembly of individual components was done
manually.
15. Second Generation (1952-64)
It used transistors in place of vacuum tubes.
They were characterized by smaller size, less heat
generation, less air conditioning, faster performance,
more reliability and low maintenance as compared to
the first generation of computers.
Still the basic component was a discrete or separate
entity. The many thousands of separate components
had to be assembled by hand into functioning circuits.
Fault finding and rectification was a tedious task due to
the same reason.
16. Third Generation (1964-71)
Integrated circuits technology made it possible to
combine a handful of circuits into an integrated one
on a small surface of silicon chip less than 5 mm
square. Third generation used such ICs.
These computers were characterized by smaller
sizes, lower heat generation, less power
requirement and more reliability as compared to
second generation.
Because of the new technology, initially it faced
many problems with the manufacturing process,
but once stabilized it required less human labour
for manufacturing.
17. Fourth Generation (1971- )
It was the research in the field of integrated
circuits that led to the development of LSIC
(Large Scale Integrated Circuits) which
could accommodate larger circuits on the
same silicon chip.
These computers are characterized by no
need for air conditioning and minimum
maintenance.
They are also cheap in cost.
