    • True

    • False

    Correct Answer
    A. True
    Explanation
    Encoding is indeed the process of converting characters into a specialized format for efficient transmission or storage.

    File compression is reducing the size of a file by converting it to a different format.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    File compression is the process of reducing the size of a file by using various algorithms and techniques. This can involve removing unnecessary data, encoding the file in a more efficient format, or compressing repetitive patterns. The result is a smaller file size that takes up less storage space and can be transmitted more quickly. Therefore, the statement that file compression involves converting a file to a different format is correct.

    What are the two main functions of an operating system?

    • Booting up the system when the computer is first switched on

    • Opening the internet

    • Protecting the computer from hackers

    • Managing memory during multi-tasking

    Correct Answer(s)
    A. Booting up the system when the computer is first switched on
    A. Managing memory during multi-tasking
    Explanation
    The two main functions of an operating system are booting up the system when the computer is first switched on and managing memory during multi-tasking. Booting up the system involves initializing the hardware components and starting the operating system. Managing memory during multi-tasking involves allocating and deallocating memory resources to different programs and processes running simultaneously, ensuring efficient utilization of available memory.

    • Laptop

    • Printer

    Correct Answer(s)
    A. Keyboard
    A. Scanner
    Explanation
    Keyboard and scanner are examples of input devices because they allow users to input data or commands into a computer system. A keyboard is a common input device that allows users to type text and enter commands. A scanner is also an input device that allows users to digitize physical documents or images and input them into a computer system. Laptop and printer, on the other hand, are not examples of input devices as they do not directly input data or commands into the computer system.

    Rate this question:

  • 9. 

    _________ is the conversion of an encoded format back into the original sequence of characters.

    Correct Answer(s)
    Decoding
    Explanation
    Decoding refers to the process of converting an encoded format, such as binary or encrypted data, back into its original sequence of characters. It is the reverse operation of encoding, where data is transformed into a different representation for various purposes like transmission or storage. Decoding is essential for understanding and utilizing the information that was previously encoded, allowing users to retrieve and interpret the original data accurately.

    Correct Answer
    A. Archive Storage
    Explanation
    Archive storage is the correct answer because it refers to a type of storage that is used for long-term data retention. Unlike other forms of storage such as hard disks, floppy disks, and USB sticks, archive storage is not meant for frequent access or modification of data. It is designed for storing large amounts of data that is rarely accessed but needs to be retained for compliance or historical purposes. Archive storage is typically more cost-effective and has higher capacity than other forms of storage, making it suitable for long-term data archiving.
