BRIDGES Bridge is a Layer 2 device. It works in Datalink layer of OSI layer model. Bridges forward frames based on MAC address. Bridges have a single incoming and outgoing port. Bridges create multiple collision domain and single broadcast domain. Bridge is a software based device. Bridges maintains a MAC address table for both of the connected LAN segments. Bridges usually divide an overloaded network into separate segments. So, it is used to separate parts of a network that do not not need to communicate frequently but need to be connected.   SWITCHES Switches can work in Layer 2 or Layer 3 depending upon the selection of the switch model. Hence switch is a multilayer device. Layer 2 switches forward frames based on MAC address. But Layer 3 switches forward data based on IP address. Switches have many ports differs according to the model. Switches can create multiple collision domains as well as multiple broadcast domain(VLANs). Switch is a hardware based devic...
