CHARLES BABBAGE



One of the creative thinker of 19Th century was the Englishman Charles Babbage(1792-1871).He is considered to be the father of computer science.Like Pascal and Leibniz,Babbage was a mathematician.And he too, wanted to build a machine that could perform difficult calculations accurately and quickly.

Babbage was Professor of Mathematics at Cambridge University and started a small model of his "Different Engine".He demonstrated his machine to the Royal Society in the year1823.The demonstration won government backing for Babbage who wished to produce a large machine able to generate reliable astronomical and mathematical tables containing values accurate to 20 decimal places.the machine was never completed because of mechanical difficulties.

However,Babbage's researches led him to develop the concept of an Analytical Engine in the year 1833,essentially a general purpose automatic calculator,which he designed in 1834.This design owed much to Jacquard's invention and incorporated many features present in modern computers.He had a concept of using binary digits (Bits) in this machine.

Using his idea about 100 years later in 1973 Mark-I was developed by Howard Aiken.Idea generated by Charles Babbage can summarized in the followings points:
1. Data and the program instruction fed in via a device using a suitable medium (punched cards)
2. Storage facilities for data and instructions.
3. A mechanized unit for calculation- a "mill".
4. A suitable output device.

GENERATION OF COMPUTER


FIRST GENERATION OF COMPUTER(1946-1958)
The first generation computer were developed during 1946 to 1958.They used large numbers of vacuum tubes as the electronic circuit and storage media..Vacuum tubes was developed by Lee Deforest in1908.They were large in size and very slow in speed,very low capacity but were very expensive.They consumed a lot of power and produced a lot of heat.They used machine language for writing the programs.This made programming extremely difficult and time consuming.

SECOND GENERATION OF COMPUTERS(1959-1964)
The second generation computers were developed during 1956 to 1964.They used transistors as the electronic circuits.The transistors were developed by John Burdeen,Walter Brattain and william Shockley in1947.Development of computers were revolutionized by the transistors.They were faster ,more reliable ,easier to operate,less expensive ,much smaller than vacuum tubes,required less electricity than of the first generation computers.They used assembly language and the high level language such as COBOL,ALGOL,FORTRAN etc.

THIRD GENERATIONS OF COMPUTERS(1965-1974)
The third generation computers were developed during 1965 to 1974.They used Integrated circuit (IC) as electronic circuit.IC circuit consists of a large number of electronic components placed on a single silicon chip by a photolithography process.Integrated circuit was developed by Jack Kilby in 1958.
This new technology (IC) made the third generation computer more reliable faster,smaller easier to operate ,high capacity ,less expensive than previous generation of computer.Third generation computer included the use of an operating system for automatic processing and multiprogramming.

FORTH GENERATION OF COMPUTERS(1975-1990)
The forth generation computers were developed during 1975 to 1990.The present days computers are included in this generation .They used large scale integration circuits (VLSI) known as microprocessor chip as electronic circuits.The first microprocessor called Intel 400 was developed by Intel corporation USA in 1971.Its size is about 0.5 cm long and less than 0.05 cm thick.In this generation the use of microprocessor made computer very faster ,capable of very high memory ,small in size and less expensive than previous generation computers.Data communication media also developed in this generation of computers.Forth generation of computers used graphical devices and language interfaces to graphic system.


FIFTH GENERATION OF COMPUTERS(1991-)
The micro processors which are extensively used as memory devices contain very pure from of silicon in crystal form.Attempts are being made by japan,Germany,and USA for the development of memory devices and main processor (microprocessors) by using protein or gallium Arsenide(GaAs), after the use of which ,it has been estimated,the capability of computer will increase millions of times.Recently,these are named as super conductors.Japan has taken keen intrest to win the race of developing super computers by using super conductors.These computers may possible by very small like micro computers

THE ORIGIN OF THE COMPUTER


The computer's was developed as results of man's search for a faster way to calculate.Computers are very fast because data and instrutions are represented as pulses within electronic circuits and they travel at the speed of light.A da's work on the computer would take aperson more than 2700 years with a hand calculator.People who contributed to make this possible where philosophers,inventors,mathematicans,programmers,etc.It has come to this stage because of their tireless effort. Counting machines didnot exits many years ago.People used to count using their fingers or arranged stones in piles or rows.They drew lines on the ground,cut notches in sticks or tied knots in strings in order to keep traks of the number of things.As the need to calculate increased,people sought tools to help them . Around the fifth century A.D.,Hindu pilosophers developed a new method of counting from 0-9.This system of counting is called the desimal method.The numbers stated above(0 to 9) are the digits.Digits is a finger or toe,and counting on one's fingers is called the digital operation.The term digital has been extended to cover any operation on distinct values which are carried out in steps.eg,"Switch the light on" is a digital operation,whereas ,operating a radio's volume control is anolog operation.The vast major of computers seen today are electronic digital computers and their names suggest that they carry out their work by performing high speed digital operation on data.The first electronic digital ccomputer were built in the mid 1940s.Their forerunners were a number of digital devices,of which the abacus is one.All these began with counting of pebbles,which of course,was the earliest method.
