A core switch is a high-capacity switch generally positioned within the backbone or physical core of a network. Core switches serve as the gateway to a wide area network (WAN) or the Internet - they provide the final aggregation point for the network and allow multiple aggregation modules to work together.

A switch, in the context of networking is a high-speed device that receives incoming data packets and redirects them to their destination on a local area network (LAN). A LAN switch operates at the data link layer (Layer 2) or the network layer of the OSI Model and, as such it can support all types of packet protocols. A network switch physically resembles a network hub. Unlike hubs, however, network switches are capable of inspecting incoming messages as they are received and directing them to a specific communications port—a technology called packet switching. A switch is a data link layer networking device which connects devices in a network and uses packet switching to send and receive data over the network. Like a hub, a switch also has many ports, to which computers are plugged in. However, when a data frame arrives at any port of a network switch, it examines the destination address and sends
