Bridges send information (data) to the specified destination, whereas hubs and repeaters do not.

Star Topology, where Hubs can act as repeaters.
Hubs and repeaters operate at the Physical Layer of the OSI Model. The Physical Layer is the first layer of the OSI Model.

Repeaters and Hubs

All network devices have some component that operates at layer 1. Only hubs and repeaters operate entirely at layer 1.
No. Only protocols that users can see on their screen are considered Presentation Layer based. Hubs and repeaters operate on the physical layer, because it doesn't do anything with the data, it simply forwards it.
Repeaters and hubs
Switches are generally considered layer 2 devices, but many are capable of operating at layers 3, 4 or higher. Most hubs are amplifying the electrical signal; therefore, they are really repeaters with several ports. Hubs and repeaters are Layer 1 (physical layer) devices.
1) Physical layer is the first layer. 2) The simplest ones operate at the physical layer are: Repeaters, conventional hubs and transceivers. 3)These devices have absolutely no knowledge of the contents of a message. They just take input bits and send them as output. Cheers, AceInfo Solutions.
