How hamming codes works?
Hamming code is a linear error-correcting code named after its inventor, Richard Hamming. Hamming codes can detect and correct single-bit errors, and can detect (but not correct) double-bit errors. In other words, the Hamming distance between the transmitted and received code-words must be zero or one for reliable communication.
Is the cyclic redundancy check better than hamming code?
It depends on what you are doing. The cyclic redundancy check will only detect an error, while the hamming code can also correct many types of errors. However to perform this correction the extra error detection parity bits required in hamming code are many more than the bits needed for cyclic redundancy check, per data byte being checked. Normally cyclic redundancy check is done on large block of data that can be resent or retried to get the correct block of data (e.g. telecommunication channels, disk sectors). Normally hamming code is done on individual bytes or words of computer memory.
How do you put correction into a sentence?
He made a correction. The correction was made. A correction is needed.

BY USING FORMULA (M+R+1)<=2r 011110110011001110101 ---- The formula d + p + 1 <= 2^p (where d is the number of data bits and p is the number of check bits) indicates that we need at least 5 check bits in order to correct single-bit errors in blocks of 16 data bits -- a (21,16) code. SECDED requires 6 check bits for blocks of 16 data bits.
How do you use a compass correction card?
First you read the compass. Then you find the correction for the heading closest to the heading the compass reads, interpolating if needed. Then you add the correction to the heading to get the corrected heading.For example, say the compass read 37 degrees and the correction card had a +2 correction for 30 degrees and a -1 correction for 60 degrees. You would interpolate a correction at 37 degrees of about +1, and add that to 37 to get a corrected magnetic heading of 38 degrees.
