Bridge vs. Switch: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on February 12, 2024
A bridge is a network device that divides a network into segments, filtering and forwarding traffic, while a switch connects multiple devices, managing and forwarding data to specific MAC addresses.
Key Differences
A bridge is a network device used to connect and segment different network sections, reducing traffic on each segment. It operates at the data link layer (Layer 2) of the OSI model. A switch, on the other hand, is a more advanced network device that connects multiple devices within the same network, forwarding data based on MAC addresses.
Bridges can filter network traffic, deciding whether to forward or block packets based on MAC addresses. This can reduce network congestion. In contrast, switches maintain a MAC address table, efficiently routing packets only to the intended recipient, which enhances network performance and security.
Bridges were commonly used in earlier networking setups to divide larger networks into manageable sections, while switches have largely replaced them in modern networks due to their ability to handle larger numbers of connections and more complex data routing.
Bridges typically have fewer ports and are suited for smaller networks. Switches come with a larger number of ports and are designed to handle more traffic, making them suitable for larger and more complex network environments.
The functionality of a bridge is more basic and limited compared to a switch. While bridges are used to filter and forward traffic between network segments, switches can do this more efficiently and support additional features like VLANs (Virtual Local Area Networks).

Bridge and Switch Definitions
Bridge
In computing, a link between two separate computer networks.
A bridge was set up to enable communication between the two different networks.
Switch
An act of changing direction or taking a different course.
After ten years in finance, she made a switch to the tech industry.
Bridge
A physical or virtual device filtering and forwarding network traffic.
To reduce congestion, a bridge was used to segment the office network.
Switch
An electrical device for making and breaking the connection in a circuit.
He flipped the switch to turn on the lights.
Bridge
A transitional path or link between two points or states.
The new policy served as a bridge between the old and new management practices.
Switch
A network device connecting multiple devices within a LAN.
We installed a switch to connect all the computers in the lab.
Bridge
A network device that connects and segments different parts of a LAN.
The network bridge efficiently connected the two departmental LANs.
Switch
A change or exchange of one thing for another.
The company made a strategic switch from traditional marketing to digital.
Bridge
A structure providing a connection over an obstacle or gap.
The Golden Gate Bridge spans across San Francisco Bay.
Switch
In rail transport, a mechanism for guiding trains from one track to another.
The train switch malfunctioned, causing a delay.
Bridge
(computing) A device which connects two or more computer buses, typically in a transparent manner.
This chip is the bridge between the front-side bus and the I/O bus.
Switch
(computer science) A command line notation allowing specification of optional behavior.
Use the /b switch to specify black-and-white printing.
Bridge
(programming) A software component connecting two or more separate systems.
Switch
A programming construct that takes different actions depending on the value of an expression.
Bridge
(networking) A system which connects two or more local area networks at layer 2 of OSI model.
The LAN bridge uses a spanning tree algorithm.
Switch
A networking device connecting multiple wires, allowing them to communicate simultaneously, when possible. Compare to the less efficient hub device that solely duplicates network packets to each wire.
Switch
(telecommunication) A system of specialized relays, computer hardware, or other equipment which allows the interconnection of a calling party's telephone line with any called party's line.
