FTP, name this method of error detection, the setting on your modem that can be even or odd.
Both the generator and checker networks are logic circuits consisting of exclusive-OR gates and in one instance an exclusive-NOR gate.  The checker can detect any odd number of errors; however, it cannot detect an even number of errors.  In this error detection system, a binary one bit is added to each piece of information transmitted over a data network so that the total number of one bits in that piece of data is a number with agreed upon division properties.
