platformsEmbedded · Network Devices
A switch is a network device that connects endpoints (e.g., workstations, servers, HMIs, PLCs, etc.) so that they can communicate and share data and resources. Switches may operate at either Layer 2 or Layer 3 of the OSI Model and intelligently forward packets across the network based on the specified address (Media Access Control (MAC) address for Layer 2 and Internet Protocol (IP) address for Layer 3). Switches are typically used to define network segments and connect the devices within a particular level of the Purdue Model.
