second generation computer

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

first generation of computer

FIRST GENERATION OF COMPUTER-:

First Generation of computer used Thermion valves, these computer was large in size and writting programs on them was difficult. Some of the computers of First Generation were

(a) ENIAC
(b) EDAV
(c) EDSAC
(d)UNIVAC

computer generation

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

HISTORY OF COMPUTER

History of computer could be traced back to the effort of man to count large number which generated various system of numeration like Babylonian System  of numeration, Greek System of numeration , Roman System  of numeration and Indian System of numeration.
The evolution of computer started from 16th century and resulted in the form that we see today

Introduction of computer

Introduction -:

In olden days people try to find new ways of making their work easier and so they try to invent new machines to make their complex tast easier
    So the invention of computer was generated , simple calculation machine , printing machine, where the early computers was not that usefull, then later on people started inventing more complex machines which were used in factories, printing press etc. This is how computer invention started

COMPUTER

                                                    WHT IS COMPUTER
                                        BASIC CONCEPT OF COMPUTER

Computer is an electronic device which can perform complex mathemathical calculation , process and transfer data
(a) Accept data
(b) Store data
(c) Process data as desired
(d) Retrive the store data and when required
(e) Print result in desired format

         Character of computer
(1) Speed
(2) Accuracy
(3) Diligence
(4) Versatility
(5) Power of remembering
(6) No IQ
(7) Storage
