    Select the field below that allows you to change the font type.  - ProProfs

    Select the field below that allows you to change the font type. 

    Correct Answer
    A.
    Explanation
    The "Font" field in a word processor or text editor allows users to choose different font styles. This field usually displays a list of available fonts (e.g., Arial, Times New Roman) that you can apply to selected text. Changing the font type alters the visual appearance of the text, allowing customization for readability or aesthetic purposes. Fonts play a significant role in how documents are perceived, whether in professional reports or creative writing.

    What is the primary function of an operating system?

    • Creating documents

    • Managing hardware and software resources

    • Browsing the internet

    • Playing games

    Correct Answer
    A. Managing hardware and software resources
    Explanation
    An operating system (OS) is the core software that manages both hardware and software resources on a computer. It serves as a bridge between the user, applications, and the computer's hardware. Key responsibilities include controlling memory, processes, peripheral devices, and file management. Without an operating system, the hardware and software of a computer wouldn't be able to communicate, making it impossible for the user to perform any tasks.

    Rate this question:

  • 6. 

    When you see no icons on the desktop, how can you open programs such as Microsoft Word?

    • Right-click to reveal all icons

    • Restart the computer

    • It is not possible to open the program if no icons are on the desktop

    • Click the start button and select the program icon from the menu

    Correct Answer
    A. Click the start button and select the program icon from the menu
    Explanation
    When icons are not displayed on the desktop, you can still access programs like Microsoft Word through the start menu. The start button, usually located at the bottom-left corner of the screen, opens a list of installed programs. From this menu, you can locate the Microsoft Word icon and launch it. This method is common on operating systems like Windows, where the start menu provides a centralized location for accessing various applications.

    Correct Answer
    A. Wireless Adapter
    Explanation
    A wireless adapter is a hardware component that allows a computer or device to connect to a wireless network. This adapter can be built into the computer or connected externally through USB. It enables communication with wireless routers or access points, which are necessary for internet connectivity. Without a wireless adapter, a computer cannot access wireless internet, making it a critical component for devices that rely on Wi-Fi connections.

    • It shows the date and time the file was created.

    • It protects the file from unauthorized access.

    Correct Answer
    A. It identifies the type of file and the program that can open it. 
    Explanation
    A file extension is like a label that tells the computer what kind of file it is and which program should be used to open it. For example, ".docx" indicates a Microsoft Word document, ".xlsx" indicates an Excel spreadsheet, and ".pptx" indicates a PowerPoint presentation.

    Rate this question:

  • 9. 

    A file extension can help you determine the format and type of a file.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    File extensions, such as .docx, .jpg, or .pdf, provide essential information about a file's format and the type of data it contains. These extensions allow operating systems and users to quickly identify which software should be used to open the file. For example, a .docx file is typically opened with Microsoft Word, while a .jpg file is an image that can be viewed with image viewers. Understanding file extensions helps avoid compatibility issues and ensures proper file handling.

    What is the difference between "Save" and "Save As" in most applications?

    • "Save" creates a new file, while "Save As" overwrites the existing file. 

    • "Save" overwrites the existing file, while "Save As" allows you to save a copy with a new name or location. 

    • "Save" and "Save As" have the same function; they both save the current file. 

    • "Save" saves the file to the cloud, while "Save As" saves it to your computer.

    Correct Answer
    A. "Save" overwrites the existing file, while "Save As" allows you to save a copy with a new name or location. 
    Explanation
    When you click "Save," the program overwrites the existing file with your changes. "Save As" allows you to create a new file with a different name, file type, or location, preserving the original file.

  • 16. 

    Which component of a computer is responsible for long-term data storage?

    • RAM (Random Access Memory)

    • CPU (Central Processing Unit)

    • HDD (Hard Disk Drive)

    • GPU (Graphics Processing Unit)

    Correct Answer
    A. HDD (Hard Disk Drive)
    Explanation
    The Hard Disk Drive (HDD) is the main storage device used for long-term data retention on a computer. Unlike RAM, which is temporary memory, HDDs store data persistently, even when the computer is powered off. This includes the operating system, software applications, documents, photos, and videos. Though newer technologies like SSDs (Solid State Drives) are also common, HDDs have traditionally been the go-to component for large-capacity storage at a relatively low cost.

    Explanation
    Private browsing mode prevents your browser from saving your browsing history, cookies, and other temporary files. This is useful for protecting your privacy when using a shared computer or when you don't want your browsing activity to be tracked. However, it doesn't make you completely anonymous or prevent websites from tracking you through other means.

    What is the difference between "cc" and "bcc" when sending an email?

    • "cc" sends a copy to all recipients, while "bcc" sends the email only to the main recipient. 

    • "cc" sends a copy to all recipients, while "bcc" sends a blind copy to hidden recipients. 

    • "cc" sends the email only to the main recipient, while "bcc" sends a copy to all recipients. 

    • "cc" and "bcc" have the same function; they both send copies to all recipients.

    Correct Answer
    A. "cc" sends a copy to all recipients, while "bcc" sends a blind copy to hidden recipients. 
    Explanation
    When you "cc" (carbon copy) someone on an email, everyone can see who else received the email. When you "bcc" (blind carbon copy) someone, their email address is hidden from other recipients. This is useful for protecting privacy or sending emails to a large group without revealing everyone's addresses.

    • It pastes the copied text or object. 

    • It undoes the previous action.

    Correct Answer
    A. It undoes the previous action.
    Explanation
    "Ctrl + Z" (or "Command + Z" on a Mac) is a universal keyboard shortcut that performs the "undo" function in most applications. It allows you to reverse the previous action, such as deleting text, formatting changes, or moving an object. This shortcut is a valuable tool for correcting mistakes and restoring previous versions of your work.

    While making an already written text bold in Word, what do you need to do first? - ProProfs

    While making an already written text bold in Word, what do you need to do first?

    • Underline the text

    • Single-click the text

    • Turn on the bold option

    • Highlight the text

    Correct Answer
    A. Highlight the text
    Explanation
    To apply formatting, such as bold, italic, or underline, to text in Microsoft Word, the text must first be highlighted or selected. This is done by clicking and dragging the cursor over the text you wish to format. Once the text is highlighted, you can apply the desired formatting by using the toolbar (e.g., clicking the "Bold" button or using the shortcut Ctrl+B). Without highlighting, the formatting will not apply to the correct section of the text.
