A Gateway is a networking hardware device that acts as a ‘gate’ to form a passage between two network devices with two high-level protocols. A gateway is a layer three network system or device used for both LAN and WAN interconnects to serve as a transitional task. In other words, it acts as a translator between two systems that use different languages, data formats, architectures, or communication protocols. The gateway acts as the entry and exit point for a network to manage the data inflows and outflows. It stores information about the routing paths of networks in communication and transmits data across them using the packet switching technique.
