The IEEE 802 project of the 1980s involved further defining the lower two layers of the OSI model. A number of standards were agreed upon during that time. Which of the following is the standard for Ethernet?
a code in which each expression conforms to specific rules of construction, so that if certain errors occur in an expression, the resulting expression will not conform to the rules of construction and
an error-detecting code based on a summation operation performed on the bits to be checked.
a check bit appended to an array of binary digits to make the sum of all the binary digits.
the ratio of the number of data units in error to the total number of data units
