Switch: A switch is a networking device that connects multiple devices within a local area network (LAN). It acts like a junction box, allowing devices to communicate with each other directly.
Gateway: A gateway is a device or software that connects different types of networks together, enabling communication between them. It's similar to an airport where people can transfer between different flights.
IP Address: An IP address is a unique numerical label assigned to each device connected to a computer network. It serves as an identifier, allowing routers to route data packets accurately based on their destination addresses.
