  1. 1Which answer below describes the function of the CPU best.
    1. AIt is the ‘heart’ of a computer system – it controls everything. It contains the circuitry which processes the instructions in the computer programs by interpreting them into actual movements of bits of data within the computer memory. It performs calculations on data pulled via ports and sends the results of processing to peripheral devices.
    2. BThe CPU is the "brains" of the computer - It completes all the calculations that are necessary for the system to function and interfaces with all testing facilities. It runs a series of diagnostic tests during the computer boot sequence that determine if the system is configured correctly.
    3. CThe CPU is a passive component in the system which is used for processing instructions or calculation. It is not an essential component unless you are required to run the system as a gaming PC.
    4. DThis is most commonly a dedicated integrated component of the motherboard however in some modern gaming PCs a separate dedicated processor can be introduced to processes the instructions in the computer programs by interpreting them into actual movements of bits of data within the computer memory.
  2. 2What does PCB stand for?
    1. APrinted Circuit Board
    2. BProcessing Circuit Board
    3. CProcessing Charged Board
    4. DPrinted Component Board
  3. 3Which answer best fits the description of a Motherboard.
    1. AThe motherboard is the most important component within a PC system. It is a PCB that houses many of the essential parts of the PC and all connections between the PC and peripheral go through it.
    2. BThe motherboard is one of the most important component within a PC system. It is a PCB that houses many of the essential parts of the PC and all carries out processing on instructions and relays these to peripheral devices on the PC.
    3. CThe motherboard is an essential component in the PC as it interfaces with all the components and processes any instructions. The CPU is mounted into the motherboard for easy of fitting but may be located elsewhere on the system should the need arise.
    4. DThe motherboard is a secondary device that is used to relay information around the system. It is a PCB that houses some PC components and connections.
  4. 4What does BIOS stand for?
    1. ABasic Input/Output System
    2. BBinary Input/Output System
    3. CBoot Instruction Occurrence Screen
    4. DBoot Instruction Output System
  5. 5What is the function of the BIOS?
    1. AIt boots up the PC.
      It checks the actual hardware configuration against the configuration data.
      It checks the operating system security data to validate logon.
    2. BIt boots up the PC.
      It checks the actual hardware configuration against the configuration data.
      It handles the input and output of the computer, allowing the operating system to use particular features of hardware within the configuration.
    3. COnce the PC has booted it checks the integrity of the operating system prior to logon.
      It checks the operating system security data to validate logon.
      It controls the flow of information to the VDU.
    4. DOnce the PC has booted it checks the integrity of the operating system prior to logon.
      It is an essential element of the security processing of the system.
  6. 6Why is the BIOS on a ROM?
    1. AROM is a type of non-volatile memory used in computers and other electronic devices. It does not lose its memory when power is switched off
    2. BROM is a type of volatile memory used in computers and other electronic devices. It does not lose its memory when power is switched off
    3. CROM is a type of non-volatile memory used in computers and other electronic devices. It loses its memory when power is removed but reloads this memory on power up.
    4. DROM is a type of volatile memory used in computers and other electronic devices. It loses its memory when power is removed but reloads this memory on power up.
