A gateway is a networking term used to describe a device that links two different networks together. These networks can be local area networks (LANs) or wide area networks (WANs). A gateway can also be referred to as a network bridge and is typically used to provide shared access to a variety of resources. Examples of gateway devices include routers, firewalls, modems, and bridges.
A gateway is a network node that functions as an access point to another network, often involving translation between protocols. It is commonly used to connect two networks that use different communication protocols, such as a local area network (LAN) and a wide area network (WAN). It can also be used to connect a LAN to the Internet. Gateways allow data to be transferred from one network to another and can also provide security measures, such as firewall protection, as well as network access control.
