(7, 3) 6. the physical part of the computer and is controlled by software. (8) 7. 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. (9) 8. non-volatile – the contents in the ROM is not lost when the computer is switched off. (3) 9. volatile because when the computer is switched off – the contents are lost, temporary memory. (3) Down 2. the number of lines allocated to a bus. The bigger it is – the more data can be transferred at a time (4, 6) 3. set of wires that connect independent components together to transfer control signals and data. (3) 4. ‘Brain’ of the computer (9) 5. the frequency in megahertz (MHz) or Gigahertz (GHz) that determines the speed of execution. (5, 5) 10. address all components except the processor – unidirectional. (7, 3)
