| BER | Bit Error Rate |
| Bandwidth | The difference between the highest and lowest frequencies of a transmission channel. It is measured in Hertz (Hz). Higher number higher data rate. |
| B-ISDN | Broadband ISDN designed to handle high bandwidth applications. This technology currently uses ATM over SONET. |

| Bootp | Bootstrap Protocol. Protocol used by a network node to find its ip address. |
| Bridge | A layer 2 device that connects two network segments and passes packets between them. |
| Broadband | A transmission system that multiplexes multiple signals into one cable. |
| Broadcast | Data packets that will be sent to all nodes on a network. |
| Byte | A series of 8 bits. |
