Basic Switch Configuration (2.1) Switches are one of the most numerous devices installed onto the corporate network infrastructure. The data link layer, or layer 2, is the second layer of the seven-layer OSI model of computer networking.This layer is the protocol layer that transfers data between nodes on a network segment across the physical layer. The Open Systems Interconnection model (OSI model) is a conceptual model that 'provides a common basis for the coordination of [ISO] standards development for the purpose of systems interconnection'.

The TLS protocol aims primarily to provide security, including privacy (confidentiality), Experience 5G . The benefits of a VPN include increases in functionality, security, and management of the private network.It provides access to resources In telecommunications and computer networking, multiplexing (sometimes contracted to muxing) is a method by which multiple analog or digital signals are combined into one signal over a shared medium.The aim is to share a scarce resource - a physical transmission medium.For example, in telecommunications, several telephone calls may be carried using one wire. In the OSI model of computer networking, a frame is the protocol data unit at the data link layer.Frames are the result of the final layer of encapsulation before the data is transmitted over the physical layer. A frame is "the unit of transmission in a link layer protocol, and consists of a link layer header followed by a packet."
