    Correct Answer
    A. Three
    Explanation
    A microprocessor typically consists of three main steps: fetch, decode, and execute. In the fetch step, the microprocessor retrieves the next instruction from memory. In the decode step, it interprets the instruction and determines the necessary actions. Finally, in the execute step, the microprocessor performs the desired operation or calculation based on the decoded instruction. These three steps are essential for the functioning of a microprocessor and form the basic cycle of its operation.

    Rate this question:

  • 22. 

    A fab must be very _______________ to protect the delicate circuits of a microprocessor.

    • Bright

    • Sterile

    • Secure

    • Secret

    Correct Answer
    A. Sterile
    Explanation
    To protect the delicate circuits of a microprocessor, a fab must be very sterile. This is because any contaminants or particles in the environment can cause damage to the sensitive circuits. A sterile environment ensures that there are no harmful particles or contaminants present, reducing the risk of damage to the microprocessor. Bright, secure, and secret are not relevant in this context and do not contribute to the protection of the microprocessor.

    Rate this question:

    Rate this question:

  • 25. 

    Electrons in a  transistor "jump" from the source to the ______________.

    • Gate

    • Semiconductor

    • Drain

    • Software

    Correct Answer
    A. Drain
    Explanation
    In a transistor, electrons "jump" from the source to the drain. The source is responsible for supplying the electrons, while the drain is where the electrons exit the transistor. This flow of electrons from the source to the drain controls the current and voltage in the transistor, allowing it to function as an amplifier or a switch. The gate, on the other hand, controls the flow of electrons by applying a voltage to the semiconductor material, but it does not directly receive the electrons. Software is not relevant to the physical operation of a transistor.
