computer science unit 1 part 1- CPU Architecture

Input devices: Keyboard, Trackpad, Screen, Microphone

Output devices: Screen display, Speakers

Processing: CPU (Central Processing Unit)

The CPU processes instructions. It is often referred to as the brains of a computer, despite functioning very differently to the human brain. The CPU can only follow one simple instruction at a time, but can carry out billions a second, whereas the human brain can carry out multiple instructions simultaneously, taking longer to process each one.

The Von Neumann diagram demonstrates the concept of storing a program's instructions and it's data in memory.

The CPU has 2 main components: 

Control Unit: Controls and coordinates all of the activity taking place within the CPU

Arithmetic Logic Unit: Where the actual arithmetic operations are carried out. 

A register is a very fast memory location within the CPU itself.

Accumulator- Holds the result of the last…
