Be able to identify several key input and output devices
Computing gained traction during World War II with the Germans inventing a device called the Enigma Machine.
The Enigma Machine was used to send secret messages to submarine commander and ship captains using a form of encryption.
The British (that's us!) wanted to be able to read these messages and so they would need to figure out how the messages are encrypted. The only problem was, the way they were encrypted changed daily, meaning there were over ten million ways it could be encrypted each day!
A man called Alan Turing built a machine that could break the Enigma code and the messages that were encoded using the Engima Machine each day.
This design was one of the early examples of electronic computers being used successfully and lead to the development of the von Neumann Architecture.
John von Neumann was a Hungarian mathematician who moved to the US in 1933.
After the Germans invaded Hungary in 1940, von Neumann chose to help the Allied war effort and was involved in the development of the first nuclear weapons.
After his research into nuclear technology, he looked into what Alan Turing had done during World War II and produced some of the most important research on computer science to date.
He is often considered one of the most influential people in the development of the computer.

Input devices provide data to the computer
Output devices receive data from the computer
Memory is like short-term memory and stores what the computer is doing at that moment
Storage devices are like the computers long-term memory, it allows it to 'remember' things

The processor is often considered to be the most significant part of a computer as it's the part of the computer responsible for making decisions and calculations.
