      Chip

    • B.

      Electronic card

    • C.

      Motherboard

    Correct Answer
    C. Motherboard
    Explanation
    The CPU, or Central Processing Unit, is a crucial component of a computer system that performs most of the processing inside the computer. It is placed on a printed circuit board called the motherboard. The motherboard serves as the main circuit board that connects all the other components of the computer, including the CPU, memory, and various peripherals. It provides the necessary electrical connections and pathways for data transfer between these components, allowing the CPU to communicate with other parts of the computer system. Therefore, the correct answer is motherboard.

    • C.

      Bits

    Correct Answer
    C. Bits
    Explanation
    RAM (Random Access Memory) is a type of computer memory that stores data and instructions temporarily while the computer is in use. In RAM, information is stored using bits. A bit is the smallest unit of information in a computer and can represent either a 0 or a 1. Since RAM is a digital storage medium, it utilizes bits to store and retrieve data quickly. Bytes and kilobytes are units of measurement used to quantify the amount of data stored in RAM, but the actual storage and retrieval of information within RAM is done using bits.
