Evolution of computers has been drastically and dramatic. Computers have been in the existence in the early 1950s, but citizen were not able to use them. When you mention the word computer most citizen only think of the Desktop Computer, but in reality computer start with our calculator.
Therefore a computer can be defined as an electronic expedient that input, process and yield information. Lets take in the case of a calculator, when adding figures you are example 1+1 =2, now you will be input data which is 1+1, this data is going to be processed straight through expanding process, to give us 2. Now 2 is the process information which is the output.
Invention Of The Vacuum
The first computers to be invented were very big, slow and time involving with tiny capabilities. Computers history and has gone straight through varied stage as they evolve beginning with the first computers, before first generation computers we had the Abacus computers which were tiny by their capabilities

The first generation were developed in the early 1940s with their architect based on weighty electronic value. They were vacuum tube dependent and without this they would not operation, from first generation computers came in the second generation computers which were good than first generation computers in performing electronic calculation but still were slow, an example of this second generation was the Abm 7000 series.
As the computer kept on evolving into generations citizen being more knowledge about them and the invention kept on being better, due to this the third computer generation was realized , this computers generations were excellent than the first and second generation computers, and use integrated circuit commonly known as Ic. An example of the third generation computers was Ibm 360 Series.
The third generation computers led to the fourth generation in computer history, with this generation, electronic function were getting better, productive and more enjoy with relatively less errors compared to the former computer . And this are the computers used in our day to day activities. They are also using Integrated Circuit Ic for their daily operation. The fourth generation computer will lead to the fifth generation computer which will be more excellent and quality to take schooling from people. This is known as artificial intelligence, in some instances robots are being used to do distinct work which were done by human beings.
