- To learn about the components inside a computer,
- To understand the difference between input and output devices,
- To learn about the impact of Alan Turing on modern computing,
- To learn about Tim Berners-Lee and the birth of the world wide web,
- To learn what the four generations of computers are.
We will cover the following subjects:
- Touch Screens,
- Alan Turing.
The World Wide Web is an amazing thing. We can search for information, find amazing images, interact with friends and family, play games and lots more. However, we mustn’t forget the amazing person who made the World Wide Web – Tim Berners-Lee. Tim Berners-Lee is a British computer scientist. He was born in London on the 8th of June 1955. His parents are Mary Lee Woods and Conway Berners-Lee. Berners-Lee worked for CERN. He has won six awards for all of his amazing work.
The Four Generations Of Computers
The first generation computers were large, slow and expensive. They were also often undependable. In 1946, two Americans called Presper Eckert and John Mauchly built the ENIAC computer with vacuum tubes other than mechanical switches. However, the vacuum tubes took up a lot of space and got really warm.
There were some obvious differences between the 1st generation of computers and the 2nd generation of computers. In 1947, three scientists invented the transistor. The transistor was much cheaper and faster than the vacuum tubes. They were also smaller and hardly gave off any heat.
People discoverd that millions of transistors could be placed within a miniature chip. This increased the power of a computer and lowered its cost. The 3rd generation of computers could carry out instructions instantly.
Ted Hoff discovered how to make an even smaller chip than before. The size of a pencil eraser. To start, it was actually meant to be used in calculators but it ended up being used in the 4th generation of personal computers.
