(7, 3) 6. the physical part of the computer and is controlled by software. (8) 7. ‘Brain’ of the computer (9) 9. transfers data from one component to another – bidirectional. (4, 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. transports control signals and is bidirectional. (7, 3) 4. the frequency in megahertz (MHz) or Gigahertz (GHz) that determines the speed of execution. (5, 5) 5. non-volatile – the contents in the ROM is not lost when the computer is switched off. (3) 8. set of wires that connect independent components together to transfer control signals and data. (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.
