    Which of the following features in Microsoft Word allows you to automatically create a list of the headings in your document?  

    • Mail Merge

    • Track Changes

    • Table of Contents

    • Word Count

    Correct Answer
    A. Table of Contents
    Explanation
    The Table of Contents feature in Microsoft Word enables users to automatically generate a list of headings from their document. By using the built-in heading styles (like Heading 1, Heading 2), Word can track these headings and create an organized table of contents, which is especially useful for long documents like reports or theses. Features like Mail Merge are used for personalizing mass communications, Track Changes is for editing, and Word Count displays the number of words in the document, but they do not handle headings.

    • Safari

    • Chrome

    • Facebook

    • Firefox

    Correct Answer
    A. Facebook
    Explanation
    Facebook is not a web browser because it is a social media platform and does not have the primary function of navigating and displaying web pages. Web browsers, such as Safari, Chrome, and Firefox, are specifically designed to access and render web content, while Facebook is a website and mobile application that allows users to connect and interact with others through social networking features.

    What is the primary purpose of a firewall in a network?

    • Block unauthorized access

    • Improve internet speed

    • Store data in the cloud

    • Clean computer viruses

    Correct Answer
    A. Block unauthorized access
    Explanation
    Firewalls are critical for securing a network by blocking unauthorized access. They serve as a barrier between a trusted internal network and untrusted external networks, such as the internet. By analyzing incoming and outgoing traffic, firewalls can detect and block harmful activities, such as hackers trying to access private data or malicious software attempting to enter the system. Modern firewalls use a combination of filtering rules, network address translation (NAT), and encryption techniques to protect sensitive information. Without a firewall, networks would be more vulnerable to cyber-attacks, data breaches, and unauthorized access, making them an essential security tool.

    What should a strong password contain?

    • Numbers

    • Capital Letters

    • Capital Letters and Numbers

    • Punctuation, Capital Letters, Lowercase Letters and Spaces

    Correct Answer
    A. Punctuation, Capital Letters, Lowercase Letters and Spaces
    Explanation
    A strong password should contain a combination of punctuation marks, capital letters, lowercase letters, and spaces. Including these elements in a password increases its complexity and makes it harder for hackers to guess or crack. Punctuation marks add special characters, capital letters add variation, lowercase letters add diversity, and spaces add additional complexity. By including all of these elements, a password becomes more secure and less susceptible to brute force or dictionary attacks.

    Which device is primarily responsible for converting digital signals to analog in a computer?

    • Modem

    • Keyboard

    • Mouse

    • Monitor

    Correct Answer
    A. Modem
    Explanation
    A modem (modulator-demodulator) is the device primarily responsible for converting digital signals from a computer into analog signals suitable for transmission over telephone lines and vice versa. When data is sent through the internet, it's in digital format, but telephone lines work with analog signals. The modem bridges this gap, converting the computer’s digital data into an analog signal for transmission, and then converting incoming analog signals back into digital data. This conversion allows digital devices to communicate through analog infrastructure, making modems crucial for internet connectivity, especially in dial-up and broadband systems.

    What is the minimum number of characters that a strong password should have?

    • 22

    • 28

    • 30

    • 16

    Correct Answer
    A. 16
    Explanation
    A strong password should have at least 16 characters. This length provides a greater level of security as it makes it harder for hackers to guess or crack the password. Longer passwords are generally more difficult to brute force or guess using common dictionary words or patterns. Additionally, a longer password increases the number of possible combinations, making it more challenging for automated password-cracking tools to break it. Therefore, having a password with 16 characters or more is recommended for ensuring the security of online accounts.
