Switch vs hub #ccna_certification #networkingbasics #cisconetworks

A hub is a basic networking device that connects multiple computers in a local area network (LAN) and broadcasts data to all connected devices, regardless of the destination, which can lead to network collisions and inefficiency.

A switch is a more intelligent device that connects devices within a LAN but forwards data only to the specific device it is intended for, using MAC addresses to determine the correct destination. This makes switches faster, more secure, and more efficient than hubs, especially in modern networks.
