The Evolution of Hardware and Computers

       There is a hidden science behind every part of our lives, and everyone on the earth is affected by its accomplishments. It is Computer Science which has transformed our societies with the rapid growth of the Internet, mobile networks and digital information. When we think about the achievements of Computer Science, we are talking about the development of computers – the most powerful machines in the world.

ENIAC

       The history of computers always amazes me. ENIAC was the first computer invented at the University of Pennsylvania  by John W. Machly and J. Persper Eckert. It uses 18000 vacuum tubes to operate, and it takes up about 2000 square feet of floor space. ENIAC has a separate unit to control executable instructions for composing a program. It utilizes function tables and switches to solve a problem. It also requires a lot of work and many programmers to finish one program.   

       If you feel interested in the history of computers, here is a brief article about it.


Transistors
A chip
       When looking at computers that we have today, I would never have been able to imagine that is how the first computer looks like. It looks so big and complicated. If we look at the history of computers, it is like a revolution of hardware. Without the progression of hardware, Computer Science would not have been like how it is today. There were two greatest inventions in the 20th century that have changed the whole modern world. They were transistors and integrated circuits (chips). A chip consists of a lot of transistors connected together. Not only does it save space, but also increases the speed of a computer.

       If you ask who invented computers, there would be no exact answer to that question because many computer scientists and inventors contribute to the evolution of computers. Finally, thanks to Computer Science’s achievements, we could not ask for a better world to live.

  1. It is indeed amazing how computers have evolved since they first came to be; our smartphones fit in our pockets and they probably have a much greater computational power than any of the first computers. I suggest adding examples of how computers have made the world and/or your live better, just to make your post a little more personal. You should also add an image of a laptop or tablet at the end of your post to visually show the evolution of computers. Overall, good job on your post.
