Generation of Computers

2. Generation of Computer
Based on the characteristics of various
computers developed from time to time, they
are categorized as generation of computers.

3. Introduction
An amazing machine! We are living in the
computer age today and most of our day to
day activities cannot be accomplished
without using computers. Sometimes
knowingly and sometimes unknowingly we
use computers. Computer has become an
indispensable and multipurpose tool. We are
breathing in the computer age and gradually
computer has become such a desire
necessity of life that it is difficult to imagine
life without it.
