Error detecting code is

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 check bit appended to an array of binary digits to make the sum of all the binary digits.

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

What is split horizon?

It prevents regular update messages from reinstating a route that has gone down.

It holds the regular updates from broadcasting to a downed link.

It splits the traffic when you have a large bus (horizon) physical network.

Information about a route should not be sent back in the direction from which the original update came.

Which of the following is true when describing a unicast address?

These are your typical publicly routable addresses, just like a regular publicly routable address in IPv4.

These are like private addresses in IPv4 in that they are not meant to be routed.

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.
