What is a network hub?

A network hub is a node that broadcasts data to every computer or Ethernet-based device connected to it. A hub is less sophisticated than a switch, the latter of which can isolate data transmissions to specific devices.

Network hubs are best suited for small, simple local area network (LAN) environments. Hubs cannot provide routing capabilities or other advanced network services. Because they operate by forwarding packets across all ports indiscriminately, network hubs are sometimes referred to as “dumb switches.”

With limited capabilities and poor scalability, network hubs had primarily one competitive advantage over switches: lower prices. As switch prices fell in the early to mid-2000s, hubs began getting phased out of use. Today, hubs are far less commonly deployed. But network hubs have some niche uses and continue to offer a simple means of networking.
