of cores goes from 2 to 4 – what is the exact effect on the performance of the
computer?
11. If the processing speed goes from 1GHZ to 4GHZ and the processor is
changed from an 8 core to a dual core processor – what is the exact effect on the
performance of the computer?

18. Moore's law predicts that the number of transistors on a circuit board would decrease (by half) every year.
19. Firmware refers to a combination of hardware and software
20. If the processing speed goes up from 2GHZ to 4GHZ and the number of cores goes from 1 to 2 – what is the exact effect on the performance of the
computer?

23. If the processing speed goes up from 1GHZ to 4GHZ and the number of cores goes from 1 to 8 – what is the exact effect on the performance of the
computer?
24. What component holds the address of the next instruction
25. Results of calculations are held in this register:
26. This holds the instruction/data temporarily after it is brought to the processor from the main memory
27. This holds the number of the current instruction being worked on
28. This would perform an operation including the logic command/word “And”
29. This would send a signal such as “Memory Read”
30. This would perform an operation such as 5+8 (1-4)
31. This would reduce the number of memory/processor transfers
32. This sends signals such as “I/O Read”
33. This sends signals such as “Memory write”
34. This doesn’t happen during the Fetch part of the cycle:
35. Which of the following is held in ROM?
36. What carries the address of the next instruction that will be fetched
37. One of the properties of an address bus is that it is uni-directional.
38. What is transferred down the data bus?
39. Which of the following definitions accurately defines a 'peripheral'?
40. RAM is a type of secondary storage
41. The purpose of the accumulator is to hold the results of a calculation.
42. "Overclocking" is adding a clock (or several clocks) to the CPU to increase the speed of the computer
43. A coprocessor is an additional processor which works as ROM
44. An embedded system refers to a mini system that is built in to each PCs internal CPU
45. Von Neuman architecture refers to a type of CPU design in which all the peripherals (including printers) are directly connected to the CPU
