    • A.

      One computer

    • B.

      Two computers

    • C.

      Three computers

    • D.

      Three computers

    Correct Answer
    B. Two computers
    Explanation
    A network can be very small, but it must consist of at least two computers. This is because a network is a collection of interconnected devices that can communicate with each other and share resources. In order for communication and resource sharing to occur, there must be at least two devices present. Therefore, having only one computer would not meet the minimum requirement for a network.

TCP/IP is the foundation of the Internet and is used for various applications such as email, web browsing, file transfer, and more.

    Rate this question:

  • 5. 

    Which type of modem provides an Internet connection through the telephone network without interrupting telephone connectivity?

    • A.

      Dial-up modem

    • B.

      Cable modem

    • C.

      DSL modem

    • D.

      Satellite modem

    Correct Answer
    B. Cable modem
    Explanation
    A cable modem provides an Internet connection through the television cable network, allowing users to access the Internet without interrupting their telephone connectivity. This type of modem uses the existing cable infrastructure to transmit data, providing high-speed Internet access. Unlike dial-up modems, which require a telephone line and can interrupt telephone service, cable modems operate independently, allowing users to use both the Internet and telephone simultaneously. DSL modems also provide Internet connectivity through the telephone network, but they can interrupt telephone service. Satellite modems, on the other hand, use satellite signals for Internet access and do not rely on the telephone network.

Text links are hyperlinks that are embedded within text, allowing users to click on specific words or phrases to navigate to another page. Image links are clickable images that redirect users to another page when clicked. Image map links are specific areas within an image that act as clickable links, allowing users to navigate to different destinations based on where they click on the image.

    To search for an exact phrase in Google or Yahoo!, you need to place the phrase in quotation marks. This ensures that the search engine looks for the exact phrase rather than individual words. By using quotation marks, the search results will only display pages that contain the exact phrase as it is typed, providing more accurate and relevant results.

    Explanation
    When you send a blind carbon copy (bcc) of an email message, the recipient of the bcc receives a copy of the email without any other recipients knowing. This means that the main recipient, as well as any other recipients in the cc or bcc fields, are unaware that the email has been sent to the bcc recipient.

    Which type of malicious software does not attach itself to files, but runs in active memory and does not require human action to cause harm or replicate itself

    • A.

      Worm

    • B.

      Virus

    Correct Answer
    D. Trojan Horse
    Explanation
    A Trojan Horse is a type of malicious software that does not attach itself to files, but instead runs in active memory. It does not require human action to cause harm or replicate itself. Unlike viruses, which attach themselves to files and require human action to spread, Trojan Horses can enter a system undetected and perform malicious actions without the user's knowledge. They often disguise themselves as legitimate programs or files, tricking users into downloading or installing them. Once inside a system, Trojan Horses can steal sensitive information, modify or delete files, or even give remote control of the infected system to the attacker.

      Run a cleanup program to remove the unwanted software

    • B.

    Running an uninstaller program would be the most useful method if you end up with unwanted or unknown software on your computer through downloading and installing programs. Uninstaller programs are specifically designed to remove software from a computer system completely. By running an uninstaller program, you can effectively remove the unwanted or unknown software, ensuring that all associated files, folders, and registry entries are deleted from your computer. This helps to free up disk space and eliminate any potential issues or conflicts caused by the unwanted software.

    • B.

      The installation of anti-virus software

    • C.

      Refusing to install any software obtained from other people

    • D.

      There is no practical way to guarantee that your computer will never be infected unless you don’t use it at all.

    Correct Answer
    D. There is no practical way to guarantee that your computer will never be infected unless you don’t use it at all.
    Explanation
    The correct answer states that there is no practical way to guarantee that your computer will never be infected unless you don't use it at all. This means that no matter what actions you take, there is always a possibility of your computer getting infected with malware. While simple common sense, the installation of anti-virus software, and refusing to install software obtained from other people can reduce the risk of infection, they cannot completely eliminate it. Therefore, the only way to guarantee no infection is to not use the computer at all.
