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