Gateway Device- What is a gateway device in networking?
A Gateway device in networking is a device that connects two or more networks that use different protocols. It translates data from one protocol to another so that it can be understood by the rest of the network. Gateways are typically used to connect a local area network (LAN) to a wide area network (WAN), such as the Internet. For example, a gateway can be used to connect a LAN using the Ethernet protocol to a WAN using the IP protocol. The gateway translates Ethernet data into IP data so it can be sent over the WAN. Gateways can be used to connect networks that use different physical media. For example, a gateway can be used to connect a LAN that uses copper wires to a WAN that uses fibre optic cables. The gateway converts electrical signals from copper wires into light signals, which are transmitted through fibre optic cables. Gateways are an essential part of any network that needs to connect to other networks. Allows devices on different networks to communicate with each othe
