the physical part of the computer and is controlled by software.

‘Brain’ of the computer
processor
2 of 12
volatile because when the computer is switched off – the contents are lost, temporary memory.
ram
3 of 12
non-volatile – the contents in the ROM is not lost when the computer is switched off.
rom
4 of 12
set of wires that connect independent components together to transfer control signals and data.
bus
5 of 12
address all components except the processor – unidirectional.
address bus
6 of 12
transports control signals and is bidirectional.
control bus
7 of 12
transfers data from one component to another – bidirectional.
data bus
8 of 12
a register that is capable of carrying out many roles which makes them more useful to programmers than dedicated registers.
general purpose register
9 of 12
the frequency in megahertz (MHz) or Gigahertz (GHz) that determines the speed of execution.
clock speed
10 of 12
the number of lines allocated to a bus. The bigger it is – the more data can be transferred at a time
word length
11 of 12
fast memory locations which are used to carry out certain things – these are used instead of using main memory because it would take a lot longer for the processor to fetch everything from the main memory so it is faster.
