If a frame is what is network switch be forwarded to a MAC address that is unknown to the switch infrastructure, it is flooded to all ports in the switching domain.

Broadcast and multicast frames are what is network switch flooded.

This is known as BUM flooding -- broadcast, what is network switch unicast, and multicast flooding. Types of networking switches There are several types of switches in networking in addition to physical devices: This results in communication without collisions.

For a price much lower than a fully managed switch they provide a web interface and usually no CLI access what is network switch allow configuration of basic settings, such as VLANs, port-bandwidth and duplex.

They may have additional features to manipulate configurations, such as the ability to display, modify, backup and restore configurations. Compared with smart switches, enterprise switches have more features that can be customized or optimized, and are generally more expensive than smart switches.

Enterprise switches are typically found in networks with larger number of switches and connections, where centralized management is a significant savings in administrative time and effort.
