  • Q7
    Which of these is true about the greater a CPU's clock speed?
    The quicker the CPU can cycle through instructions and complete tasks
    The more detailed the completion of tasks are done
    The slower the CPU handles instructions

  • Q8
    What impact does having more cores have on a CPU?
    Less cores are better for faster processing
    More cores means that the CPU does not need a heat sink
    The more cores, the more instructions can be processed at one time
    The more cores, the slower instructions are processed

    What is Level 1 Cache?
    Extremely fast but small (between 2-64KB), located very close to the processor
    The lowest part of the memory triangle
    Extremely slow and large in memory (2-64GB) and located far from the processor
    Extremely fast but large in memory (2-64GB) , located very close to the processor

  • Q11
    The fetching process in the fetch-decode-execute cycle carries out what role?
    The previous instruction and any data involved to be fetched from main memory
    It calculates the information passed through and sends out the outcome
    It holds the memory location for the next instruction
    The next instruction and any data involved to be fetched from main memory
