Computer Architecture 0.0 / 5 ? Computingsystem architectureASAQA Created by: BeckyQuinCreated on: 02-06-15 10:08 57648312109 Across 1. address all components except the processor – unidirectional. (7, 3) 7. ‘Brain’ of the computer (9) 8. the physical part of the computer and is controlled by software. (8) 9. set of wires that connect independent components together to transfer control signals and data. (3) 10. volatile because when the computer is switched off – the contents are lost, temporary memory. (3) Down 2. non-volatile – the contents in the ROM is not lost when the computer is switched off. (3) 3. transfers data from one component to another – bidirectional. (4, 3) 4. 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) 5. transports control signals and is bidirectional. (7, 3) 6. the frequency in megahertz (MHz) or Gigahertz (GHz) that determines the speed of execution. (5, 5)
