  1. 1The following devices are examples of input devices: [blank_start]mouse[blank_end], [blank_start]keyboard[blank_end], [blank_start]webcam[blank_end]
    The following devices are examples of output devices: [blank_start]monitor[blank_end], [blank_start]speaker[blank_end], [blank_start]printer[blank_end]
    1. Amouse
    2. Bkeyboard
    3. Cwebcam
    4. Dmonitor
    5. Espeaker
    6. Fprinter
  2. 2What is the CPU (Central processing Unit) responsible for?
    1. AJust the output devices
    2. BAll the processing in the computer
    3. CKeeping the motherboard cool so it can work more efficiently
  3. 3The main parts of the CPU are the [blank_start]Control Unit[blank_end] and the [blank_start]ALU[blank_end] (which stands for [blank_start]Arithmetic and Logic Unit[blank_end].)
    1. AControl Unit
    2. BALU
    3. CArithmetic and Logic Unit
  4. 4The CPU processes data by carrying out three steps: [blank_start]fetch[blank_end] (instructions are transferred from the memory to the CPU), [blank_start]decode[blank_end] (the control unit determines what the instructions mean) and [blank_start]execute[blank_end] (the instruction is executed using the ALU for instructions involving logical or mathematical operations.) This whole process is called the [blank_start]fetch-execute cycle[blank_end].
    1. Afetch
    2. Bexecute
    3. Cdecode
    4. Dfetch-execute cycle
  5. 5What is the definition for Clock Speed?
    1. ARepresents the number of instructions the CPU can process in a given time - the number of fetch-execute cycles it can perform
    2. BThe amount of time the CPU can run for and perform the fetch-execute cycles
    3. CHow fast the CPU can perform one fetch-execute cycle
  6. 6The clock speed is measured in megahertz (million) and gigahertz (billion) and the higher the clock speed, the faster the CPU will run.
    1. ARichtig
    2. BFalsch
  7. 7Multiple core processors are processors with [blank_start]more[blank_end] cores than single core processors. If there are [blank_start]more[blank_end] cores, this means that more instructions can be processed at the same time, [blank_start]improving[blank_end] the computers performance. For example, a quad core processor would have a [blank_start]better[blank_end] computer performance than a dual core processor as [blank_start]4[blank_end] instructions can be processed in a [blank_start]shorter[blank_end] time.
    1. Amore
    2. Bless
    3. Cimproving
    4. Dnot improving
    5. Ebetter
    6. Fworse
    7. Gshorter
    8. Hlonger
    9. I4
    10. J3
    11. K2
    12. L1
    13. Mmore
    14. Nless
  8. 8What is Cache Memory?
    1. AHigh speed memory in the CPU that is used to store a copy of frequently used instructions so they can be accessed more quickly
    2. BA small section of memory designated to storing specific data that needs protection - for example security data or details
    3. CEveryday memory that the computer uses in ever fetch-execute cycle
  9. 9[blank_start]Level 1[blank_end] cache is the smallest and closest to the CPU - sometimes it is built into the CPU itself.
    [blank_start]Level 2[blank_end] cache is usually on a separate chip next to the CPU, is larger but slower in comparison.
    1. ALevel 1
    2. BLevel 2
    3. CLevel 3
  10. 10Why is Cache Memory used?
    1. ABecause the processing speed of the CPU is limited by the speed that data can be supplied by the RAM, which is slower. It is easier to get data from the cache memory as it is closer to the CPU.
    2. BBecause it frees up space inside the rest of the computer.
    3. CBecause the RAM can get easily full with data so it is needed as an 'overflow'
