A hub is a layer 1 (physical) device because it does not use any part of the packet header to direct the packet to the right destination, it just broadcasts to all connected computers.
Physical layer
hub is the device that is used to extend the lan segment and used at layer1 that is physical layer.

hub work at physical layer of osi model
1)Hub is a layer 1(physical layer)device whereas switch is a layer 2(datalink) device. 2)Hub sends data to all ports unnecessarily.so in this way it shared bandwidth whereas switch sends data to exact that port which required it after learning destination MAC address.so here is a dedicate bandwidth.

Hub
There are no layer 1 switches; switches run at layer 2 or 3. A hub is a layer 1 device.
TheHub work on layer 1 i.e. Physical layer of OSI Model

A hub is a layer 1 network device (hardware), and the 'web' is a software concept implemented by different protocols and multiple devices.
