Computer Hardware...
...by Anabel Jacobsen
Learning Objectives:
- 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.
My Task:
To create an online flyer to educate Year 6 pupils about computer hardware and the history of the computer using text, pictures and videos with an online application called Smore.
We will cover the following subjects:
- Drives,
- CPU,
- RAM/ROM,
- Motherboards,
- Inputs/Outputs,
- Touch Screens,
- Alan Turing.
Alan Turing
Without Alan Turing, our lives today would be completely different. He was born in 1912 and lived in India until 1926 when his father retired. As well as helping to program the first commercial computer, he helped break German codes in World War II. In 1952, Turing was arrested and tried for homosexuality. Two years later on the 7th of June 1954, Alan Turing committed suicide. In 2012, the Olympic flame was passed from one person to another in front of a statue of Alan Turing, on what would have been his 100th birthday. In 2014, George Osborne announced a £42m fund to help make the United Kingdom a world leader in big data and algorithm. An Alan Turing Institute is to be founded to ensure that Britain leads the way in big data. There is also a limited edition Alan Turing Monopoly game and a street named after him.
Tim Berners-Lee
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
Before the type of computer we have today, we went through some generations...
1st Generation
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.
2nd Generation
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.
3rd generation
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.
4th Generation
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.

Drives
A drive is capable of storing and reading information. Examples of drives are: floppy drives, hard disk drives and CD-ROM drives. For more types of drives and more information about them, head to http://www.computerhope.com/jargon/d/drive.htm.

CPU
CPU is short for Central Processing Unit. It is also known as 'the brain of the computer' and was first developed at Intel. It was made in the early 1970s. The CPU handles all instructions it gets from hardware and software on the computer. For more information, go to http://www.gsmarena.com/glossary.php3?term=cpu.

RAM/ROM
ROM chips are usually used in game consoles such as the original Nintendo DS and The Gameboy. RAM chips are commonly used in computers. The main difference between RAM and ROM is a ROM chip doesn't require constant power to retain the information.
