1. Gateway

A gateway is a networking device that combines the functions of a router, modem, and often a wireless access point into a single device. It serves as the connection point between a local area network (LAN) and the internet, enabling devices to access the internet wirelessly. Gateways typically include built-in Wi-Fi capabilities, allowing multiple devices to connect to the internet without the need for additional equipment. They manage network traffic, assign IP addresses, and provide security features to protect the network from unauthorized access. Gateways are commonly used in homes and small businesses to establish wireless internet connectivity and create a local network for sharing resources.
