Which of these devices would least likely be found on a modern network?

A) Hub
B) Router
C) Modem
D) Switch

Hubs are a primitive network device that operates in the physical layer of the OSI model. They are used to connect devices together in a LAN and broadcast the data to all connected devices. Modern networks use switches instead of hubs as switches enable faster data transfer with better security, management, and more efficient use of bandwidth. Therefore, a hub is the least likely to be found on a modern network. Routers and modems are still widely used, and switches have replaced hubs, so they are more commonly found on modern networks.
