A CDE Definition
A source or destination device in a networked system. For example, a user's PC is an end device, and so is a server. Network switches, routers and other equipment work in between to enable messages to travel from one end device to the other. See edge router.
Also called an "access router," it is a router that sits at the periphery of a network. Contrast with "core router," which is a router that resides in the middle of the network. See router and WAN router. See also edge device.
