SECOND GENERATION OF COMPUTER -:
In second generation the computer of central processing unit (CPU) , memory , programming language and output and input units were developed .
The programming language such as COBAL, FORTRAN were developed during this period
Some of the computers of second generation were
(a) IMB 1620
(b) IBM 1401
(c) CDC 3600

first electronic computer
ENIAC-:
It was the first electronic computer built in 1946 at University of Pennsylvania, USA by John Eckert and John Mauchy. It was named Electronic Nummerical Intergrator and calculation (ENIAC). The ENIAC was 50 feet long, 30 tone, contained 18,000 vacum tube, 70,000 registers , 10,000 capacitors and required 150,000 watt of electricity

COMPUTER GENERATION-:
The evolution of computer started from 16th century and resulted in the form that we see today. The present day computer, however has also undergone rapid change during the last 50 years. This period duing which the evolution of computer took place can be divided into five distinct place as Generation of computer

mechanical and electrical computer
MECHANICAL AND ELECTRICAL COMPUTER
In the begning of 19 century the mechanical calculator was developed to perform all sort of mathematical calculation upto the 1960 it was wiely used later so mechanical calculator was replaced by electric motor
ELECTRONIC-:
The electronic calculatorwas run with the elctro tube which was quite bulky, later it was replaced with transistor and as a result the size became small in size
The modern electronic computer can compute all kinds of mathematical computation and mathematical function. It can also be used to store some data permanently

INVENTION OF MODERN COMPUTER
(a) NAPIER's BONES-:
An English mathematician John Napier built a mechanical device for the purpose of multiplication in 1617 AD
The device was known as Napiers Bones
(b) SLIDE RULE-:
English mathematician Edmund Gunter developed the slide rule. The machine could perform operation like additional,subtration ,multiplication and division
(c) PASCAL'S adding and subtratory machine-:
Blaise Pasacal developed a machine at the age of 19 that could add and subtract, the machine consist of wheel, gear and cyl;inder

Ancient computer
ANCIENT COMPUTER
It took over generation for early man to built mechanical device for counting large number.
The first calculating device called ABACUS was developed by the Egyptian and Chinese people.
The word ABACUS mean calculating board
