    What does CPU Stand for? - ProProfs

    What does CPU Stand for?

    • Central Prompting Utility

    • Central Processing Unit

    • Constant Processing Utility

    • Critical Processing Unit

    Correct Answer
    A. Central Processing Unit
    Explanation
    The correct answer is "Central Processing Unit." The CPU is the main component of a computer that performs most of the processing inside the computer. It interprets and executes instructions from the computer's memory, performs calculations, and manages the flow of data between different parts of the computer. The CPU is often considered the "brain" of the computer, as it carries out the majority of the computer's operations.

    Two hardware components are used to cool off the computer. Select the two items. - ProProfs

    Two hardware components are used to cool off the computer. Select the two items.

    • Heat Sink

    • Power Supply

    • Fan

    • Vents

    Correct Answer(s)
    A. Heat Sink
    A. Fan
    Explanation
    Heat Sink and Fan are the two hardware components used to cool off the computer. A heat sink is a passive cooling device that absorbs and dissipates heat from the computer's central processing unit (CPU) or other components. It helps to maintain the temperature within safe limits. On the other hand, a fan is an active cooling device that circulates air and helps in dissipating heat from the computer. Together, these components work to prevent overheating and ensure the proper functioning of the computer.

    • Voltage,

    Correct Answer
    A. Voltage, Power, Resistance, Current
    Explanation
    There are four basic units of measurement in electrical systems, often referred to as the "fundamental electrical units." These are:
    Watts (W): This is the unit of power, which measures the rate at which energy is being consumed or produced.
    Amps (A): This is the unit of current, which measures the flow of electric charge in a circuit.
    Voltage (V): This is the unit of potential difference or electromotive force, which measures the force driving the current between two points in a circuit.
    Ohms (Ω): This is the unit of resistance, which measures the opposition to current flow in a circuit.
    Together, these four units form the basis for understanding and analyzing electrical systems, circuits, and power.

    Memory that saves frequent information is called ___________. - ProProfs

    Memory that saves frequent information is called ___________.

    Correct Answer(s)
    Cache
    Explanation
    Cache is a type of memory that stores frequently accessed information for faster retrieval. It is designed to reduce the time taken to access data from the main memory by keeping a copy of frequently used data closer to the processor. This helps in improving the overall performance of the system by reducing the latency involved in fetching data from the main memory. Therefore, cache is the correct term to describe the memory that saves frequent information.
