Detailed explanation-1: -Layer 2 refers to the data link layer of the network. This is how data moves across the physical links in your network. It’s how switches within your network talk to one another. Installing Layer 2 on your infrastructure gives you high-speed connectivity between devices.
Detailed explanation-2: -A network switch is a physical device that operates at the Data Link layer of the Open Systems Interconnection (OSI) model–Layer 2.
Detailed explanation-3: -Switches are one of the traffic directors on the network, and traditionally operate at Layer 2. They allow for the connection of multiple devices in a LAN while decreasing the collision domain by employing packet switching.
Detailed explanation-4: -Network-to-network connections are what make the Internet possible. The “network layer” is the part of the Internet communications process where these connections occur, by sending packets of data back and forth between different networks.
