👉 HUB, switch, and router are all networking devices that are used to connect multiple devices together to form a network. However, they differ in their functionality and the way they handle network traffic.

🟢 HUB: A hub is a simple networking device that allows multiple devices to connect to a network. When a device sends data to the hub, the hub broadcasts the data to all connected devices on the network, regardless of whether or not they are the intended recipients.

🟢 SWITCH: A switch is a more advanced networking device that operates at the data link layer of the OSI model. When a device sends data to a switch, the switch analyzes the data and forwards it only to the intended recipient device.

🟢 ROUTER: A router is a networking device that operates at the network layer of the OSI model. It is used to connect multiple networks together and direct data traffic between them. A router uses routing tables to determine the best path for data to take on its way to its destination.

👉 In summary, a hub simply broadcasts all data to all devices on the network, a switch sends data only to the intended recipient, and a router connects multiple networks together and directs traffic between them.
