No one who lives in the modern times is allowed to know nothing about the history of one of the most important machines that controls our lives. This machine would be the computer – the machine in front of which we spend lots of hours a day and the machine which has brought so much controversy in our lives because of this.

The first computers were some mechanical machines manufactured by Blaise Pascal or Charles Babbage. In fact, we can even state that these were the machines which set the bases of what we see as computers today. George BOole also had an important impact upon the history of computers due to his theory, according to which there were two states: true and false. In fact, these operations have been named after him.

Claude Shannon was the one who put his theory into practice, combining it with electronic circuits. He was the one who introduced different voltages for each type of such operation. The first computer as we know it was created by Konrad Zuse, a German engineer, who created the Z3. ENIAC was the next one, a computer which was created for the government of the United States of America, the government using it for calculating trajectories.

The second generation of computers started with the invention of the transistors, which replaced the classic and uncomfortable electronic lamps. This generation brings new micro-programming languages and a lot of models manufactured by IBM.

Last but not least, the third generation led to the great explosion in this domain. This is when the integrated disk was made and this led to the manufacture of the Intel microprocessor. Computers have been evolving ever since, becoming an indispensable object in our lives.
