Explanation

A hub is a basic Layer 1 (Physical Layer) networking device whose sole function is to connect multiple devices together on a network. Unlike a switch, a hub has no intelligence - it simply repeats any incoming signal out to all other connected ports, regardless of the intended destination. It does not filter traffic (that is a firewall's role), does not control traffic flow (that is a router or switch), and does not serve information (that is a server's role).
