Question
Which of the following device is used only in LAN (Local Area Network)?1 pointModemRouterNICAll of the above
Solution
The correct answer is NIC (Network Interface Card). This device is used only in a Local Area Network (LAN).
Here's why:
-
Modem: This is not exclusive to LAN. A modem is a device that provides access to the Internet.
-
Router: This is also not exclusive to LAN. A router is a device that forwards data packets along networks. It connects two or more logical subnets, which do not necessarily map one-to-one to the physical interfaces of the router.
-
NIC (Network Interface Card): This is a card installed in a computer so that it can connect to a network. Every device on a LAN has a NIC, so this is the only device in the options that is used only in a LAN.
-
All of the above: Since Modem and Router are not exclusive to LAN, this option is incorrect.
