Unlike a network switch or router, a network hub has no routing tables or intelligence on where to send information and broadcasts all network data across each connection. The most commonly used hub is an ethernet hub. A hub acts like a repeater: all data that arrives to one port is sent to all other ports (without looking at IP address for the data's destination). Network Hub Definition Hub is a physical device used in a network that is in a distributed environment like an internet network or wired LAN and basically observed in physical layer.

Emergence of hubs is a consequence of a scale-free property of networks. The hub then receives that request and transmit it to the entire network. Dual-speed hubs internally consist of two hubs with a bridge between them. In a hub, a frame is passed along or “broadcast” to every one of its ports. The device is thus a form of multiport repeater. This differs from a switch environment, where each port is allotted a dedicated amount of bandwidth. Network devices (Servers, Workstations, Printers, Scanners etc) are attached to the hub by individual network cables. Since every packet is repeated on every other port, packet collisionsaffect the entire network, limit… In the context of a network, a switch is a computer networking device that connects network segments. With limited capabilities and poor scalability, network hubs had primarily one competitive advantage over switches: lower prices.
