    Which part of the computer is rated by how many bits of information they can receive in one second?

    • A.

      Memory

    • B.

      Modem

    • C.

      Drive bay

    • D.

      Microprocessor

    Correct Answer
    B. Modem
    Explanation
    A modem is the correct answer because it is a device that allows computers to connect to the internet. Modems are rated by how many bits of information they can receive in one second, which is known as the data transfer rate. This determines the speed at which data can be transmitted over a network. Memory, drive bay, and microprocessor are not directly related to the data transfer rate of a computer.

    Formulas are instructions that you enter to perform calculations.  For example, enter the number 350 in cell B1; enter the number 450 in cell B2; enter the formula =B1+B2 in cell B3.  The value 800 is displayed in cell B3.  If a value changes in cell B1 or B2, the formula will always add the two and show the correct sum in cell B3. If B1 is 25, B2 is 20, and B3 has the formula =B1-B2, what is the sum that will show in B3?

    • A.

      45

    • B.

      5

    • C.

      -5

    • D.

      None of the above

    Correct Answer
    B. 5
    Explanation
    The formula in cell B3 is =B1-B2, which subtracts the value in cell B2 from the value in cell B1. Therefore, if B1 is 25 and B2 is 20, the sum that will show in B3 is 5.
