The idea behind CRC calculation is to look at the data as one largebinary number. This number is divided by a certain value and the remainder ofthe calculation is called the CRC. Dividing in the CRC calculation at firstlooks to cost a lot of computing power, but it can be performed very quickly ifwe use a method similar to the one learned at school. We will as an examplecalculate the remainder for the character m —which is 1101101in binary notation—by dividing it by 19or 10011. Please note that 19 isan odd number. This is necessary as we will see further on. Please refer toyour schoolbooks as the binary calculation method here is not very different the decimal method you learned when you were young. It might only look alittle bit strange. Also notations differ between countries, but the method issimilar.-The idea behind CRC calculation is to look at the data as one largebinary number.
