What is a switch? In the context of networking, a switch is a device that connects devices together in a computer network, enabling them to communicate with each other by exchanging data packets. A switch operates at the data link layer of the OSI model. With a switch, it's possible for...
A data frame isfloodedto all ports in the switching domain if it is forwarded to a MAC address that the switch infrastructure is not familiar with. Data frames formulticast and broadcast are also flooded. This is known asbroadcast, unknown unicast and multicast flooding. This capability makes a...
If no matching entry is found in the MAC address table, the switch sends the packet out of all ports except the port on which it is received. This process is similar to broadcast. After the reply from the destination is received on a port, the switch learns the new MAC address to port...
A Network Switch Explained A network switch (often called an Ethernet switch) is essential networking hardware that provides wired connectivity to other networking equipment and devices using packet switching to receive and intelligently forward data to the destination device. Network switches transmit ...
Switching in IT and computer networking is the transfer of data packets, or blocks of data, through a network switch.
What is a router? Just as a switch connects multiple devices to create a network, a router connects multiple switches, and their respective networks, to form an even larger network. These networks may be in a single location or across multiple locations. When building a small business network...
Most switches, however, are layer 2 switches. Layer 2 switches most often connect to the devices in their networks using Ethernet cables. Ethernet cables are physical cables that plug into devices via Ethernet ports. What is an unmanaged switch? What is a managed switch?
