    The keyboard is an output Device used to input data to the computer

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The given statement is incorrect. The keyboard is actually an input device used to input data into the computer, not an output device. It allows users to type and enter information, commands, and text into the computer system. Output devices, on the other hand, are used to display or present information from the computer to the user, such as monitors, printers, and speakers.

      In Word Processing to Embolden means:

    • A.

      To increase the size of the font.

    • B.

      To Render the font.

    • C.

      To increase the outline of the font.

    • D.

      None of the Above.

    Correct Answer
    C. To increase the outline of the font.
    Explanation
    The correct answer is "To increase the outline of the font." When you embolden text in word processing, it means to make the font appear thicker and bolder. This is achieved by increasing the outline of the font, making it more prominent and easier to read. Increasing the size of the font refers to making the text larger, while rendering the font refers to the process of converting the text into a visible form on the screen or in print. Therefore, the correct answer is to increase the outline of the font.

    The given statement is false because networks can be connected in different buildings as well. Networks can be connected through various means such as Ethernet cables, Wi-Fi, or even through wide area networks (WANs) which can connect networks across different buildings or even different locations. Therefore, networks are not always connected in the same building.
