(5, 5) 4. transfers data from one component to another – bidirectional. (4, 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) 10. the physical part of the computer and is controlled by software. (8) Down 2. 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) 3. ‘Brain’ of the computer (9) 6. address all components except the processor – unidirectional. (7, 3) 7. transports control signals and is bidirectional. (7, 3) 9. non-volatile – the contents in the ROM is not lost when the computer is switched off. (3)
