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...
