A hub is a hardware device used to boost the signal. It operates at Layer 1 of the OSI layer also known as the Physical layer. It is also called a repeater. Usually you connect one port to the main switch and connect computers and devices to the other ports. In other words, it allows multiple computers to communicate with each other. Hubs are being replaced with switches as hubs do not provide error-checking capabilities. They pass bad packets along and can lead to networks getting congested. Switches operate at Layer 2 and is far better than hubs. It is rare to find true hubs these days.

There are many ways to connect network computers. The HUB, seldom used nowadays due to the low cost of SWITCHES, is a shared media access device that shares bandwidth between all devices connected to it. For instance, if you have 100Mbps coming into the hub, all devices connected to the hub will share this speed. A switch perserves the bandwith between machines giving you better network performance.

From Wikipedia:
An Ethernet hub or concentrator is a device for connecting multiple twisted pair or fibre optic Ethernet devices together, making them act as a single segment. It works at the physical layer of the OSI model, repeating the signal received at one port out each of the other ports (but not the original one). The device is thus a form of multiport repeater. Ethernet hubs are also responsible for forwarding a jam signal to all ports if it detects a collision.

A hub is the hardware that the network points are plugged into and provides the transport mechanism between them. These things are only really used in the home or very small networks.

HUB is like a power outlet but it does not give power
IT is for Local are network
HUB is multiport
u can connect so many PCs to one hub...

a hub is a hardware networking device. it is use to share network service, passive. it shares the ammount of bandwidth it recieves to all the exiting ports.
