Generations Of A Computer

    Almost now a days  all are using  compoters..without the computers the survival is nothing.So,we       will  learn about the   generations of a computers and how it will  be  from 1 st  genaration to now..

  

 1 st Genaration Computers:-

       Firstly the father of computer is Charles Babbage..So,when he developed a computer it is called 1st generation..that is in 1948.  Vaccume tubes  are used as components and with help of these tubes of liquid mercury and magnetic drums are used for memory...so now also we are using these in  auxilary memory..these are having  some disadvantages..like very big power consumption etc.,

2 nd Generation Computers:-

    By the disadvantages of  1st genaration   the  2 nd generation computers are developed and came into market..In 1954 the transistors are used instead of   vaccume tubes..and memory is used with the help of  Magnetic  Cores..

Ex:- Honeywell. realiability was increased and size  was reduced.

3 rd Genaration Computers:-

  In  1965   the integrated Circuits was  introduced.the first integrated circuits (IC's) are used in the  first operationg systems.. At this time the 1st online computers was improved.Here the magnetic roles and punch cards are  used..

4 th Generation Computers :-

  In  1975  computer  made with  Micro Processors..i.e., chips..It is also called as Personal Computers(PC).We measure the chips in terms of microns.Query languages ,sheets, report writers are first introduced  and most of users are  familier with this..

5 th Generation Computers:-

  In 1980  In the computers the LSI  which includes artificial intelligence (AI) and true distribution processing .The computers are classified  into four types  according to the  industrial  requirments..

   

 1) Micro Computers:-

      these are the longest range  in the computers..these are having restricted  computing capacity..these are used for teaching purposes in schools.

2)Mini Computers:-

      these systems are having  the capabilities like sharing info, sharing resources,.We can use these systems for networking in java ,LAN,WAN,MAN etc.,

3) Main Frame Computers:-

      these are called servers,with this we can operate hundreds of systems.It is having large storage capacity.these are used in business.

  

4) Super Computers:-

     These are the highest range of computers .This was  first designed by a "param" in 1998..with our technology..these systems are used in satellite technology.biotechnologies,weapon deasigning,air craft,weather forecasting..
