Where did computer science start? When
did we start programing? One of the earliest machines that was
designed was the Charles Babbage. This machine used mechanical energy
to perform calculations. The input was designed to handle punch
cards. Regardless of what machine it was there were several
components that were necessary to compute. The input was needed or
else there would be nothing to compute, the processing units that
would make the calculations, the memory that holds values and the
control unit which directs all information, and lastly the output,
without which there would be no point in making the calculations
without seeing the results. Later on more and more advances in
technology allowed for more, faster, and more efficiently. Mechanical
energy changed into electrical energy. Buttons replaced punch cards,
followed by later innovations such as the key board and mouse and
touch screens. The devices became smaller and faster with the
invention of the microchip. Calculations that were once done by using
punch card machines that could take up a room can now be done in a
device which can fit in one's hand.

Hi John!
ReplyDeleteLooks like I'm the first comment for this blog post. First of all I like the very old primitive computer picture you placed in your article. It might actually be a good idea to shrink it a bit since it does go off the center guidelines just a bit. I do like the structure of how you wrote your blog post but it does seem to be a bit short. Otherwise great job!

Hi Chiem,
ReplyDeleteNice to read your post. I saw the machine last Saturday at Computer History museum. Just as you said, the machine used mechanical energy to perform calculations. As a great computer pioneer, Charles Babbage designed the first automatic computing engines. The first real differential engine was created 153 years after it was designed.
From room size machine to palm size device, computers have underwent huge change. Human is smart. Science is great.
Your post is informative and clear. It will be better if you can divide it into paragraphs.
Anyway, it is a good post.
