TOPIC: Diff between Bridge n Switch?

Whats the difference between a Switch and a Bridge?

Re: Diff between Bridge n Switch? 15 years 4 months ago #1998

Hope this helps.....

Generally, a bridge has only two ports and divides a collision domain into two parts. All decisions made by a bridge are based on MAC or Layer 2 addressing and do not affect the logical or Layer 3 addressing. Thus, a bridge will divide a collision domain but has no effect on a logical or broadcast domain. No matter how many bridges are in a network, unless there is a device such as a router that works on Layer 3 addressing, the entire network will share the same logical broadcast address space. A bridge will create more collision domains but will not add broadcast domains

A switch is essentially a fast, multi-port bridge, which can contain dozens of ports. Rather than creating two collision domains, each port creates its own collision domain. In a network of twenty nodes, twenty collision domains exist if each node is plugged into its own switch port. If an uplink port is included, one switch creates twenty-one single-node collision domains. A switch dynamically builds and maintains a Content-Addressable Memory (CAM) table, holding all of the necessary MAC information for each port

I have been told that bridges connect LAN segments of dissimilar protocols where as switches do not.

You can use a bridge between an ethernet and token ring but switches cannot..

Is this true?

There are 2 types of bridges: tranparent bridges and translating bridges.

Transparent bridges move data between 2 LAN segments that are the same.

Translation bridges move data between dissimilar LAN segments (such as Ethernet and Token Ring).

A switch is a multi-port switch. Normally doesn't do any translating (however, I do believe there is such a thing as a translating switch, but I've never seen one).

hi friends :P

A bridge is an internetworking device used to contact separate LANs or link two network segments, and to filter information between them as well as traffic collisions, and other networek problems. A switch is a network acces device that provides a centallized point for LAN communications,media connections and management activities-like Hub.
