      Four

    • D.

      Five

    Correct Answer
    B. 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:

  • 11. 

    The first step of a microprocessor is ______________.

      Execute

    • C.

      Fetch

    • D.

      Crash

    Correct Answer
    C. Fetch
    Explanation
    The first step of a microprocessor is the fetch stage. During this stage, the microprocessor retrieves instructions from memory. It fetches the next instruction in the program and prepares it for execution. This is an essential step in the instruction cycle of a microprocessor, as it ensures that the processor has the necessary instructions to perform its tasks.

    Rate this question:

    • D.

      Decode

    Correct Answer
    D. Decode
    Explanation
    The second step of a microprocessor is "Decode". After the instruction is fetched from memory in the first step, the microprocessor needs to decode the instruction to determine what operation needs to be performed. This involves interpreting the binary code of the instruction and identifying the specific operation and operands involved. The decoding process prepares the microprocessor for the next step, which is executing the instruction.

      Crash

    • D.

      Decode

    Correct Answer
    A. Execute
    Explanation
    The third step of a microprocessor is "Execute". After the previous steps of fetching and decoding the instruction, the microprocessor executes the instruction by performing the necessary operations. This step involves carrying out arithmetic, logical, or control operations based on the instruction received. The execution step is crucial as it determines the actual processing and manipulation of data within the microprocessor, leading to the desired outcome or result.

    • D.

      0s and 1s

    Correct Answer
    D. 0s and 1s
    Explanation
    A binary code is made up of 0s and 1s because binary is a base-2 numbering system that uses only two digits, 0 and 1, to represent all numbers and characters. Each digit in a binary code is called a bit, and it can be either 0 or 1. This is the fundamental concept behind digital computing, where data is represented and processed using binary code.

    A transistor is made of silicon, which is a semiconductor material commonly used in electronic devices. Silicon has unique properties that make it suitable for use in transistors, such as its ability to conduct electricity under certain conditions. Transistors are crucial components in electronic circuits, and they play a vital role in amplifying and switching electrical signals. By using silicon as the base material, transistors can efficiently control the flow of current and perform various functions in electronic devices.

    Rate this question:

  • 23. 

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

    • A.

      Gate

    • B.

      Semiconductor

    • C.

      Drain

    • D.

      Software

    Correct Answer
    C. 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.

    • C.

      Fab

    • D.

      House

    Correct Answer
    C. Fab
    Explanation
    Microprocessors are made in a fab, short for fabrication facility. A fab is a specialized manufacturing plant where the process of creating microprocessors takes place. It involves various complex steps such as designing, etching, and assembling the intricate electronic components that make up a microprocessor. Fabs are equipped with advanced machinery and cleanroom environments to ensure precise and controlled manufacturing conditions.

    Rate this question:

  • 25. 

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

    • A.

      Bright

    • B.

      Sterile

    • C.

      Secure

    • D.

      Secret

    Correct Answer
    B. 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.
