A computer network is always subject to signal degradation and traffic overload. Computer network monitoring is mandatory to check such issues. If this is not done, the performance of the computer network will be less than optimal.

Whatever be the medium used to transmit messages or information over the computer network, signal degradation cannot be avoided. Computer network monitoring tools known as cyclic redundancy checks (CRCs) are used to compare and match the transmitted signal and the signal received by the requisite destination computer. Dexadine's CRC Tool is one such program.
