'Burst errors' diaporamas de présentation

10.1 Single-bit error

10.1 Single-bit error. Note :. A burst error means that 2 or more bits in the data unit have changed. 10.2 Burst error of length 5. Note :. Error detection uses the concept of redundancy, which means adding extra bits for detecting errors at the destination. 10.3 Redundancy.

A few more things about binary numbers

A few more things about binary numbers. Errors. Recall that using a binary representation maximizes our tolerance of fluctuations without loss of the information represented. Still errors occur. They have fall into two categories: Errors that cannot be interpreted as a 1 or 0
