    10-Base-T wire has a max segment length of what?

    • A.

      No Limit

    • B.

      185m

    • C.

      200m

    • D.

      100m

    Correct Answer
    D. 100m
    Explanation
    The correct answer is 100m. 10-Base-T wire refers to Ethernet cables that use twisted pair wiring and have a maximum segment length of 100 meters. This means that the cable can transmit data effectively up to a distance of 100 meters before signal degradation occurs. Beyond this distance, the quality of the signal may deteriorate, leading to slower data transmission or potential data loss.

    C. 1024
    Explanation
    The correct answer is 1024 because a kilobyte is a unit of digital information that is equal to 1024 bytes. This is because computers use a binary system where each unit is a power of 2, and 1024 is the closest power of 2 to 1000. Therefore, a kilobyte is commonly understood to be 1024 bytes rather than 1000 bytes.
