IT Interview Questions:What are router interfaces? What types can they be?
The interfaces on a router provide network connectivity to the router. The console and auxiliary ports are used for managing the router. Routers also have ports for LAN and WAN connectivity.
he LAN interfaces usually include Ethernet, Fast Ethernet, Fiber Distributed Data Interface (FDDI), or Token Ring. The AUI port is used to provide LAN connectivity. You can use a converter to attach your LAN to the router. Some higher-end routers have separate interfaces for ATM (Asynchronous Transfer Mode) as well.
Sync and Async serial interfaces are used for WAN connectivity. ISDN (Integrated Services Digital Network) interfaces are used to provide the ISDN connectivity. Using ISDN, you can transmit both voice and data.
