    Which does not describe a public network:

    • The devices on the network are "visible" to devices outside the network

    • Local Area Network

    Correct Answer
    A. Local Area Network

It is not inherently public, as it is usually privately owned and operated by an organization or individual for their own use. Public networks, on the other hand, are accessible to devices outside the network, and they can include Wide Area Networks (WANs) as well as the internet. Therefore, option C does not fit the description of a public network.

Therefore, we cannot conclude whether Cesar lives in Cebu City or if he celebrates Sinulog Festival.

    Bella must use EDSA to get to work. Bella has a meeting today at 9:00 AM. If Bella misses the meeting, she probably will lose a major account. EDSA is closed all day due to repairs. Based on the above, we can conclude that:

    • Bella will not be able to get to work.

    • Bella will probably not be able to reschedule the meeting.

    • Bella will lose a major account.

    • None of the above can be concluded.

    Correct Answer
    A. Bella will lose a major account.
    Explanation
    Bella needs to use EDSA to get to work, but it's closed all day for repairs. She has a crucial meeting at 9:00 AM, and missing it could result in losing a major account. Since EDSA's closure prevents her from getting to work on time, it is reasonable to conclude that Bella will miss the meeting and, consequently, lose the major account. Other conclusions cannot be definitively drawn from the given information.

    A wireless access point is a device that allows wired communication devices to connect to a wireless network using Wi-Fi, Bluetooth, or related standards. It usually connects to a router. However, it cannot be a modem as modems are used for different purposes, such as converting analog signals to digital signals for internet connectivity. Therefore, the statement "Could also be a modem" does not describe a wireless access point.
