Hub vs. Bridge: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on February 10, 2024
A hub is a network device that connects multiple Ethernet devices together, operating at the physical layer, while a bridge connects different network segments, operating at the data link layer.

Key Differences

A hub is a basic networking device that connects multiple Ethernet devices, operating at the physical layer of the OSI model. A bridge, on the other hand, connects two or more network segments, operating at the data link layer.

Hubs transmit data to all connected devices, leading to possible data collisions. Bridges intelligently manage data flow and reduce collisions by learning the MAC addresses of connected devices.

A hub’s indiscriminate data broadcasting can lead to network inefficiencies. Bridges enhance network performance by filtering and forwarding data based on MAC addresses.

Hubs are used within a single network segment. Bridges, however, can connect and extend two different network segments, even if they use different protocols.
