GENERATION OF COMPUTER.

THE GENERATION OF COMPUTER

    * Genaration in computer talk is a step in technology It provides a treamwork for growth of computer inderstria .
    * Generation was used to disting which between raring .
    * now a day s it has been extended to enclude more hard ware and software software which together make up anentirel computer system ..
       

        FIRST GENERATION OF COMPUTER

    * THE computer produced beetween 1942 - 1955 at termed as first generation of computer .
    * the first generation computer were electronic they used vaccume tube to store instructions ..
    * magnetic drums where used to memory ..
    * they ware too bulkyinsize , requaring large rooms for gnstullation .
    * this vaccume tubes or valve occupied large space due to which the size of the 1st generation of computer was very large it s computer capuciy was very           limited and operating speed was very slow ..
    * they ware very expensive to opparate and in addition to using a grate deal of electricity..  
3rd GENERATION OF COMPUTER.

* the computer produced 1966- 1975 a timed as 3rd generation of computer ..
* thy were more powerful can 2nd genertion computer they were capable of pertorming about one millons instructions..
* they ware much smaller then 2nd generation computer and requiring smaller space
* in 3rd generatio contegrated circuit replace the  trangisterwhich was devloped by J.s kilibi. this devlopedment is known as st (large scale - integration ).
* thi used in the field of airline reser vation system inter active more programming etc...s type of computer hard the capacity to stre hundred mega bytes of an networks as intorduce during this period this system were interduce during this period this system were time shareing multi usser multi programming in nature ..
* this type of computer mainly used in field of airline reser vation system inter active more programming etc... 

he computer produce between 1956-1965 at term as second generation computer .
* they ware more than 10 time faster that 1st generation compuer. 
* they ware much smaller then 1st generation computer .
* in 2nd generation of computer transistore replaced vaccume tubes in computer ..
* transistros were made of .semi wnducter, materials like, silicon, germanium etc...
* one trasistor can pertorm the basks of more vsccumtubes.this reduceses the sile and cast ..
* the high level language ware devloped during this period..
