Which of the following is not a network device?
Which of the following is not a network device?
A Core is not one special device that you find on a network. When people talk about networks the word "Core" usually means the Core Layer. This is the level of a network that is designed like a big hierarchy. The Core Layer is in charge of making sure data gets from one place to another quickly and without any problems. It does this across the backbone of the network. You might hear people talk about "Core Switches" or "Core Routers". When they just say "Core" they are usually talking about a part of the network, not a specific device like a hub or a switch. The Core is, like a layer that helps everything work together.
