It receives the signal in the network before it becomes weak, regenerates the original bit pattern and puts the refreshed copy back in to the link.Bridges: These operate both in the physical and data link layers of LANs of same type.

What is Protocol Data Unit?
The data unit in the LLC level is called the protocol data unit (PDU). The PDU contains of four fields a destination service access point (DSAP), a source service access point (SSAP), a control field and an information field. DSAP, SSAP are addresses used by the LLC to identify the protocol stacks on the receiving and sending machines that are generating and using the data. The control field specifies...
