  30. 30Name the four registers of the CPU. Hint: MAR & MDR.Program Counter
    Memory Address register
    Memory Data register
    Accumulator.
  31. 31Who came up with the architecture that we use in most computers today?Von Neumann
  32. 32Which register holds the memory ADDRESS of the instruction for each cycle?Program Counter
  33. 33Which register stores the results of the ALU?The accumulator.
  34. 34MAR or MDR? Holds the memory address about to be used by the CPU?MAR.
  35. 35MAR or MDR? Holds the data or instruction about to be used by the CPU?MDR
  36. 36CPUs follow a cycle. Rearrange the order to make it correct: Decode Execute FetchFetch Decode Execute
  37. 37What is the cycle that CPUs follow?Fetch, Decode, Execute
  38. 38Describe the Fetch Process in three sentences with no more that 8 words or abbreviations in each.Copies memory address from PC to MAR.
