an error-detecting code based on a summation operation performed on the bits to be checked
the ratio of the data units in error to the total number of data units
a code in which each expression conforms to specify rules of construction, so that if certain errors occur in an expression, the resulting expression will not conform to the rules of construction and
a check bit appended to an array of binary digits to make the sum of all the binary digits.
This address identifies multiple interfaces and the anycast packet is only delivered to one address. This address can also be called one-to-one-of-many.
Packets addressed to a unicast address are delivered to a single interface.
These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap.
Packets are delivered to all interfaces identified by the address. This is also called one-to-many addresses.
