How Computers travel a long journey

We all are very familiar with computers, we know them and we can use them well.We all use them at our home either laptop or desktop. But only few of us knows how does the computer generation started, how computers came in our life and became part of our life. This article is about history of computers and all about how they became an important part of our life.

Computer! This is the name of that device which we can not avoid to use though if we decide to do so. Computers became an essential part of our every day life. Do you know how they did travel such a long journey?
Charles Babbage tried to make a computing device and he succeeded. He made a computing device using vacuum tubes. That was the first computer and this was the first generation of computers. In first generation magnetic elements were used to store data.
After coming semiconductors, the computing changed its way completely.
Transistors were being used rather than vacuum tubes. This solved many problems of computers like in case of vacuum tubes more heat is generated but in case of transistors it is not. Thus transistors started second generation of computers. Second generation computers were faster and smaller than first generation computers.
Second generation computers were small but not as they should be. Then Integrated Circuits (IC) made their place in ICs replaced the transistors and computers became more smaller and compact. And this is the Third Generation of computers.
In third generation microprocessors are being used. the computers we use are of third generation.
The Fourth Generation of computers is the upcoming generation like the The Sixth Sense Device of Pranav Mestry. Thus today's computer is not just made in one day, it had already traveled a long distance and going to travel.

Hello Kiran,
Thank for this information of Generation of Computers.The fourth generation computers are best.The motion sensing device created by pranav mistry is very useful in our day to day life.We can directly watch our delay of flight timings without doing extra work like open internet on our Smart Phone.We can read the reviews about book by this device.We can capture any image by just movement of our hands.
