Generation of Computer Notes For Bank Exam -
Today we are providing some study material for Generation of computer. "Computer is basically an auto-electronic device whose work is to solve logical and arithmetic problems or in other words “Computer is a device or a flexible machine which converts raw analog data to digital understandable information".
As the time passed, the computer device made a permanent place in our lives and became a dependable machine which can remove the work pressure and can do work much faster. The computer generation started in the year 1946 with the first computer named as ENIAC.
Generation of computer
|1||First Generation||1946-1959||Vaccum Tube|
|3||Third Generation||1965-1971||IC (Integrated Circuits)|
|4||Fourth Generation||1972-2010||VLSI (Very-large-scale integration)|
|5||Fifth Generation||2010-onward||ULSI (Ultra Large scale integration)|
In the first stage of computer, we used vacuum tubes. These vacuum tubes are slower in processing speed and used machine language which was hard to understandable as instruction in 0 or 1.These first generation computer was bigger in size even occupied entire room , generates lot of heat and was very expensive So these can’t be used continuously for longer duration of time.
In the second generation of computer, we used transistors. Vacuum tubes replaced the transistor. Second generation saw the improvement in speed and size but heat produced was still damaging to the system. Language used was assembly language, which means it was easy to understand as instructions consist of words.
In Third generation of computer was used to integrated circuits. ICs were reduced the size, increases storage capacity and faster the speed of computer. These extremely small electronics can perform calculations and store data using either digital or analog technology.
Vital stage in the development of computer was microprocessor. Intel was first to develop microprocessor. In microprocessor tens of millions of transistor invented on single chip which is very small in size and also have very high processing capabilities. Microprocessor supports multiple task This generation saw the development of computer for home use developed by IBM.
Fifth generation saw the start of artificial intelligence, features like voice recognition are made possible with artificial intelligence as machine able to respond in natural language and have capability to learn and organize themselves.
