Charles Babbage was an English mathematician, philosopher, mechanical engineer and an inventor, not bad to have that many titles. What he is most famous for is to be found at the museum of science in London, the "difference engine" that he began his work on in 1822 and finished in 19th century; it is composed of over 25.000 parts and weighed over 13000 KG. The difference engine, was originally created to calculate and print mathematical tables. This is also what we can call the computers "origin".Another person announced in the lecture was a pretty lady with the name Ada byron, she is the daughter of the famous poet, Lord Byron. Her mother did her best to make sure her daughter did not end up as a poet as her dad, so she was brought up to be a mathematician and scientist.
She became really fascinated by Babbage work, she even suggested that a machine of that kind could be used to produce music, that it could be used for both practical and scientific use, something that is really sick that they thought about for that many years ago.
The work of Ada Byron got recognised as the first “computer program". The development of computer was taken on by an English man called Alan Turning, he wrote the paper called “on computable numbers". He used his expertise to make the machine called “the bomb" that was developed to break the Germans secret Enigma codes.In the 1950s the first commercially produced computer came out from IBM. The computers produced at that time were for military and governmental use. These computers were too big for any regular person to have in their home, so everyone understood that the computers needed to be minimized dramatically.
In 1965 a really smart man with the name Gordon E. Moore said that the capacity of microchip's needed to be doubled every second year. The trend has continued for more than half a century and is not expected to stop until 2015 or later, but what do we do then?
The next step in computer development was to make it useful for everyone, it needed a common language that everyone could understand to handle a computer, the nerd that developed that was the ever famous Bill Gate. On another place in a garage some other nerds Steve Jobs and Steve Wozniak and created their own company called Apple.
In 1960 a company with the name RAND corporation came up with the idea of internet, what we can say is one of the histories biggest networking inventions. The world that was big a decade ago is now just in front of us. There is nothing you cant find there. People often mistake the Internet for the Web but this is actually two different things. You can look at it this way, every webpage on the internet is just a collection of files images and sounds stored on a computer,and the internet is more like a network of computers. When we are using a web browser like safari, Opera to look at different web pages like CNN, we are looking at that specific page, not the files on the computer. We can update people of our life trough Facebook and blogs like this, read a newspaper from India, upload and share a homemade movie on in minutes with the rest of the world.
this weeks tutespark was to find at least three different non-electronic digital devices:
the first one i found that i think is a non electronic digital adviser is morse code.
The second one i found after a long time researching for it was something called the Braille a-system. It is said about the braille system that it is a "tactile system of raised dots representing letters of the alphabet." This is the way blind people use to communicate . The web page says it was invented in Paris by a man named Louis Braille in 1929.
The third i found was what is called Abacus:
Abacus was invented in China 5000 years ago.
An abacus is used to track numbers as you do the computing rather than acutally doing the computing.
