  • 1. 

    The power supply in a computer is there to:

    • A.

      Increase the voltage to make computer faster

    • B.

      Enable the computer to work at a safe 240 volts ac

    • C.

      Reduce the voltage from 240V dc to about 12 V ac

    • D.

      To provide a very stable low voltage

    • E.

      Speedy tricks

    Correct Answer
    C. Reduce the voltage from 240V dc to about 12 V ac
    Explanation
    The power supply in a computer is responsible for reducing the voltage from 240V DC to about 12V AC. This is necessary because the components in a computer require lower voltages to operate safely and efficiently. By converting the high voltage from the main power source to a lower voltage, the power supply ensures that the computer receives a stable and appropriate level of power.

    A computer program is described as having 8-bit color. How many colors can it display?

    • A.

      8

    • B.

      16

    • C.

      64

    • D.

      128

    • E.

      256

    Correct Answer
    E. 256
    Explanation
    An 8-bit color computer program can display 256 colors. This is because 8 bits can represent 2^8 (2 raised to the power of 8) different values, which is equal to 256. Each bit can have two possible values (0 or 1), and with 8 bits, there are a total of 256 possible combinations. Each combination represents a different color, allowing the program to display a total of 256 colors.

    What happened if the computer does not switch on?

    • A.

      RAM broken

    • B.

      Sound Card broken

    • C.

      Power supply problem

    • D.

      The VGA cable problem

    • E.

      Socket is not working

    Correct Answer
    C. Power supply problem
    Explanation
    If the computer does not switch on, it is likely due to a power supply problem. The power supply is responsible for providing electricity to all the components of the computer, and if it is not functioning properly, the computer will not receive the necessary power to turn on. This could be caused by a faulty power supply unit or issues with the power source itself. It is important to check the power supply and ensure it is working correctly in order to resolve the issue.

    What is the Maximum memory that Hard Drive can have?

    • A.

      500GB Hard Drive

    • B.

      250GB Hard Drive

    • C.

      670GB Hard Drive

    • D.

      2X 500GB Hard Drive

    • E.

      50000MB Hard Drive

    Correct Answer
    D. 2X 500GB Hard Drive
    Explanation
    The maximum memory that a hard drive can have is not determined by the size of the individual hard drives, but rather by the capacity of the system or computer that the hard drives are connected to. Therefore, the correct answer of "2X 500GB Hard Drive" does not provide any information about the maximum memory that a hard drive can have.
