What the layer of hub?

Answer 1

The layer of hub refers to a networking component that connects multiple devices within a local area network (LAN). It operates at the physical layer of the OSI model, primarily functioning as a basic data distributor by broadcasting incoming data packets to all connected devices. Hubs are relatively simple devices and do not filter or manage traffic, which can lead to collisions and reduced network efficiency compared to more advanced devices like switches. While largely outdated, hubs were foundational in the evolution of network architecture.
