Briefly describe how computers have evolved over generations?
Title: Evolvation of computer over generation's
Introduction: A computer is an electronic device that manipulates data and information. It has the
ability to store ,retrieve and process data. Over the decades computer have evolved. In the beginning
computers were very large and slow , Now a days computers have become smaller and faster , people
use them anywhere .Now they become more advanced. For example : business email list is used by
professional reach to more customers.(1)
Abacus Computer :
Abacus is first calculating device. It is also called counting frame . It consists of a bamboo frame with
beats sliding on wires. Bead frame consist of beats divided in to tens they use to teach arithmetic. (2)
1. First Generation : (1946-1959) First electric computer was invented by J.P.Eckert and
J.W.Mauchy called ENIAC stands for “Electronic Numeric Integrated and Calculator “
Example
ADVAC
IBM-701
2. Second Generation : (1959-1965) They consists of transistor. Assembly language and punch
cards were used for input.
Example
IBM 7094
CDC 1604
3. Third Generation : (1965-1971) They based on integrated circuits . Robert Noyce and Jack
Kilby. IC was invented in 1958-59 . IC contains number of transistors.
Example
PDP-8
IBM 360
Forth Generation : (1971-80) They based on microprocessor . A microprocessor is used to
perform logical and arithmetic function in any program. GUI (Graphical user interface )
technology offer more comfort.
