lecture 09: Error Sources, Detection and Correction
• Network errors are in the form of corrupted data or lost data.
• Network errors occur naturally on all networks due to electrical noise and distortion
and must be detected and corrected by either hardware or software.
• Bit Error Rates (BERs) are calculated as the number of bits in error divided by the
number of bits transmitted. A BER of 1 in 100,000 might be shown as 1:105
or simply
as a BER of 10-5
.
• Errors often occur in bursts where many bits in a sequence will be in...
