Second Generation Of Computer

Second Generation Of Computer In 1948 transistor was invented which replace the vacuum tubes later, due to this size has been shilling and consumed less electricity. In 1958 magnetic core memory was developed which is used store data. Various assembly language program develop like a COBOL( common business oriented language), Forthan ( formula translation) , Pascal, etc. which replace the machine language. In this generation we built the computer business and University and government companies most popular manufacturers are controlled data Honeywell, IBM (international business machine) spery rand,etc example IBM 1401. It also consume more electricity and a space assembly language are difficult because it based on computer architecture .

First generation of computer

First generation of computer In 1919 John Presper and Mouchly discover the first digital computer which was made of vacuum tubes Named ENIAC this computer having 18000 vaccum tubes 70000(seventy thousand) Resistor and 5 million solding join its weight is 160 ton and consumed 150 kilowatts electricity. MARK-1 was the first general purpose computer that speed is 1000 times   1940 JOHN VON Nueman gives the concept of first computer and design EDVAC in 1947 this machine has storage memory. In 1951 UNNAC-1 build by Remington Rand become the first commercial computer used in US(United State) sensuous Bureau. Advantage of first generation computers are big in size but they perform function faster than human ,huge in size, consume more electricity machine dependent and works on machine language only.  

History of computer

History of computer classification based on memory size There are 5 types of computer 1.          MICRO COMPUTER (1 TO 4 MB) 2.          MINICOMPUTER (4 TO 12MB) 3.          MIDI OR MAINFRAME COMPUTER( 2 MB TO 128 MB) 4.          SUPER MINICOMPUTER (1 MB TO 80 MB) 5.          MAXI OR SUPERCOMPUTER (8 MB TO 10 GB) Generation Of Computer first generation of computer First generation 1950 1.          Vacuum tubes 2.          Very large size 1.          Very slow speed 2.          Less memory capacity 3.    ...

NATURE OF COMPUTER

Automatic :- computer are automatic in nature it does not require every time human presence. Versatile :- it versatile in nature means it perform different type of task. Diligence :- a computer has diligence's capacity means it is constant in their effort an application human suffer from tiredness and like of concentration but computer does not.

Measurement Unit Of Data

Measurement Unit Of Data 0,1= bit (2) 4 bit =1 nibble (2 2 ) 8 bit= 1byte (2 3 ) 1024 byte=1 kilobyte/KB (2 10 ) 1024 KB=1Megabyte/MB( 2 20 ) 1024 MB= 1 Gigabyte/GB (2 30 ) 1024 GB=1 Terabyte /TB( 2 40 ) 1024 TB=1 Pet byte/PB( 2 50 )
