    devices to connect directly to each other without using a central router or switch?
    A Cellular network Correct Answer Incorrect Answer
    B Ad-hoc network Correct Answer Incorrect Answer
    C Local Area Network (LAN) Correct Answer Incorrect Answer
    D Wide Area Network (WAN) Correct Answer Incorrect Answer
    E Virtual Private Network (VPN) Correct Answer Incorrect Answer

    Solution

    An ad-hoc network allows devices to connect directly to each other without the need for a central router or switch. This type of network is temporary and is often used in mobile computing where devices need to communicate peer-to-peer for tasks like file sharing or collaborative work in the absence of an established network infrastructure. Why Other Options are Wrong: a) A cellular network relies on centralized towers and routers. c) LAN typically involves wired connections through a router or switch. d) WAN connects devices over a broad geographic area using routers. e) VPN provides secure communication over the internet but still relies on existing network infrastructure.
