What is the Difference between Switch and Bridge?

Answer Posted / rakesh kumar agrawal

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
