A hub is one of the simplest networking devices. It connects multiple computers in a network, allowing them to communicate with each other. However, hubs operate in a basic way: they broadcast incoming data to all connected devices, regardless of the intended recipient. This can lead to unnecessary network traffic and potential slowdowns, especially in larger networks. Despite its limitations, a hub is still useful in small setups where cost-effectiveness is a priority.

What is a Switch?

Unlike a hub, a switch is a smarter networking device. It identifies the devices connected to it and sends data only to the intended recipient. This targeted communication reduces network congestion and improves overall efficiency. Switches also support full-duplex communication, meaning devices can send and receive data simultaneously. This makes switches ideal for medium to large networks, where performance and reliability are critical.
