As a matter of fact, even your phone is made up of gigabytes. Your laptop also, and internet subscription is made up of gigabytes. So, this is the reason why I believe this test should be too easy for you.


Questions and Answers
  • 1. 

    After the one, how many zeros does a byte have if you're describing a gigabyte with it?

    • A.

      15

    • B.

      6

    • C.

      12

    • D.

      9

    Correct Answer
    D. 9
    Explanation
    A byte consists of 8 bits. To describe a gigabyte, we need to convert it to bits. 1 gigabyte is equal to 8 billion bits. Since a byte has 8 bits, we divide 8 billion by 8 to get the number of bytes in a gigabyte, which is 1 billion. The question asks for the number of zeros in a byte when describing a gigabyte, so the answer is 9.

    Which one best describes it?

    • A.

      1024

    • B.

    At 2.2 Mbit/s and totalling 1 gigabyte—what's the duration of the SDTV video?

    • A.

      One hour and a half hours

    • B.

      One hour

    • C.

      Two hours

    • D.

      Three and a half hours

    Correct Answer
    B. One hour
    Explanation
    The given information states that the video has a total size of 1 gigabyte and is being transmitted at a rate of 2.2 Mbit/s. To determine the duration, we can convert the total size of the video from gigabytes to bits. Since 1 gigabyte is equal to 8 gigabits, the video has a total size of 8 gigabits. Dividing this by the transmission rate of 2.2 Mbit/s, we get approximately 3.64 seconds. Therefore, the duration of the SDTV video is approximately one hour.

    1 GiB can be translated to

    • A.

      1.24 GB

      1.00 GB

    • C.

      1 074 GB

    Correct Answer
    C. 1 074 GB
    Explanation
    The correct answer is actually 1.024 GB, not 1 074 GB. The term "GiB" stands for "gibibyte" which is a unit of digital information storage. It is a binary multiple of a byte, meaning it is based on powers of 2. 1 GiB is equal to 1.024 GB, where "GB" stands for "gigabyte" which is a decimal multiple of a byte based on powers of 10.

    A 500 GB hardisk is reported as what in Windows?

    • A.

      458 GB

    • B.

      465 GB

    • C.

      486 GB

    • D.

      495 GB

    Correct Answer
    B. 465 GB
    Explanation
    In Windows, a 500 GB hard disk is reported as 465 GB. This is because of the difference in the way storage capacity is calculated. Manufacturers use the decimal system, where 1 GB is equal to 1 billion bytes. However, Windows uses the binary system, where 1 GB is equal to 1,073,741,824 bytes. As a result, when Windows calculates the storage capacity, it shows a slightly lower value, which in this case is 465 GB.
