HISTORY OF COMPUTER !

we all know that computers are an important part of our life and we all use it in our daily life for great work.
but, do you know about computer history??
if not...than this post is for you....In this post, i will tell you a lot about the history of computer.
so let's begin........


about COMPUTER word : 

Computer is derived from a Latin word "COMPUTARE" which means to "TO CALCULATE" or "TO COUNT". so, the word of computer means a 'device that performs computation'.

FATHER OF COMPUTER :

Charles Babbage was considered to be the father of computer because of hid inventoin and concept of the Analytical Engine in 1837. Unfortunately, because of funding issues, this computer was never built while Charles Babbage was alive. 


HISTORY :

In the 19th century, a mathematics professor Charles Babbage introduced everyone with the computer. He has composed an Analytical Engine on the basis of which today's computers are also working.
simply.., the computer can be classified into three generations. Every generation was a certain time and with the generations, our computer was developed and we started getting even better computers.

FIRST GENERATION (based on VACUUM TUBES) 

Time : 1940-1956
Vacuum Tube was used to control and transmit electronic signals in this generation computer. the size of vacuum tube used in this generation was quite large due to which it occupied a considerable space. they used to produce a lot of heat while using them and the possibility of malfunction was very high. And apart from this, it's ability to calculate was very low. 
This generation has built-in computer electronic Numerical Integrator and Computer (ENIAC), EDSAC (Electronic Delay Storage Automatic Computer), UNIVAC (Universal Automatic Computer) and so on.

SECOND GENERATION (based on TRANSISTOR) 

Time : 1956-1963
the Transistor was invented in the second generation of computers and it was now used in computers. these Transistors were more capable than Vacuum Tube and size was also small compared to them. it's capacity was high and now the computer used to work faster. now the computer started to become smaller than first generation and started working fast.

THIRD GENERATION (based on INTEGRATED CIRCUIT)

time : 1963-1971
Integrated Circuits used to be used in this generation's computer, which was much smaller than the transistor. the capacity of this generation was greatly increased and now with one computer many computers could be used simultaneously. because it used a small integrated circuit made of silicon chip. so it's size was now much smaller. now the generation of computers used to be used at the level of the house. the speed of this generation was changed from micro seconds to nano seconds.

FOURTH GENERATION (based on MICROPROCESSOR)

Time : 1971-till now
Today we all mostly use computers of this generation, which includes the Laptop. In this generation, by using microprocessor it's size has become quite small, which we can take with us anywhere.
with the help of very large scale integrated(VLSI) in this type of computer, thousands of transistors can be combined together and its speed can be made very fast.
this is the biggest revolution in the field of computer.


FIFTH GENERATION (based on Artificial Intelligence)

Time : in future
the next generation of computers that are currently working and some of the success has been achieved is Computer based on Artificial Intelligence. this type of computer will be able to do all the work by itself.
we can see such a computer in Robots and different types of machines, which will be able to do more than human work.

so guys... this was the history of computer.

thank you for being here !!
