<p data-start="359" data-end="690">A hub is a basic networking device that operates at the physical layer of the OSI model. It receives data packets from one device and broadcasts them to all other connected devices, regardless of the intended recipient. This method can lead to network congestion and inefficiencies, making hubs less suitable for larger networks.

<h4 data-start="692" data-end="716">What is a Switch?</h4>
<p data-start="717" data-end="1057">A hub & switch, on the other hand, is an intelligent networking device that operates at the data link layer. Unlike a hub, a switch forwards data only to the specific device it is intended for, using MAC addresses to determine the correct path. This targeted communication improves network efficiency, reduces collisions, and enhances security.

<h4 data-start="1059" data-end="1076">Conclusion</h4>
<p data-start="1077" data-end="1383">While hubs are simple and cost-effective, switches are the preferred choice for modern networks due to their ability to manage traffic efficiently. As networking technology continues to evolve, switches have largely replaced hubs in most environments, ensuring faster and more reliable data transmission.
