    True or false: Formatting is burning (writing) magnetically successive sectors that make up each of the tracks on a disk or diskette, thus leaving them magnetized.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Formatting is the process of preparing a disk or diskette for data storage by dividing it into tracks and sectors. During formatting, each sector is magnetically marked as either empty or occupied. This process involves burning (writing) data onto the sectors, which leaves them magnetized. Therefore, the statement that formatting is burning magnetically successive sectors on a disk or diskette, thus leaving them magnetized, is true.

    Correct Answer
    A. True
    Explanation
    Recording is achieved as an audio recorder by the action of a magnetic field of reversible polarity (NS or SN), which magnetizes the track that the field is acting on. This means that the statement is true.

    Which company developed the CD - ROM?

    • Time warner

    • Ned

    • Sony y Phillips

    Correct Answer
    A. Sony y Phillips
    Explanation
    Sony and Phillips developed the CD-ROM. The CD-ROM, which stands for Compact Disc Read-Only Memory, is a type of optical disc storage medium. It was jointly developed by Sony and Phillips in the early 1980s. The CD-ROM revolutionized the way data was stored and accessed, allowing for large amounts of information to be stored on a single disc. This technology paved the way for the development of other optical disc formats, such as DVD and Blu-ray.

    The capacity of a DVD with respect to a CD ...

    • It is enhanced by a larger disk.

    • It is enhanced by use of a greater portion of the disk.

    • It is enhanced by a higher density of data.

    Correct Answer
    A. It is enhanced by a higher density of data.
    Explanation
    The capacity of a DVD with respect to a CD is enhanced by a higher density of data. This means that more information can be stored on the same physical disk space, allowing for a larger amount of data to be stored on a DVD compared to a CD. The higher density of data is achieved through advancements in technology and the ability to store information in a more compact and efficient manner.

    • 25 GB if it is a single layer.

    • The same as a DVD ..

    Correct Answer(s)
    A. About 50 GB double layer.
    A. 25 GB if it is a single layer.
    Explanation
    Blu-Ray discs have a capacity of about 50 GB for double layer discs and 25 GB for single layer discs. This means that a double layer Blu-Ray disc can hold approximately 50 gigabytes of data, while a single layer disc can hold around 25 gigabytes. The capacity of a Blu-Ray disc is greater than that of a DVD.
