What is the difference between an OSI NSAP address and a Network Entity Title (NET)?

A.
A NET is a special version of an NSAP address restricted to 8 bytes for the Area Address,
System ID and the N-Selector byte.

B.
A NET is an NSAP address with the N-selector byte set to 00.

C.
The System ID field of the NSAP address does not uniquely identify a node.

D.
To identify a Domain, an NSAP address must be used because a NET can only identify an
Area.

E.
Network Entity Titles do not have to start and stop on byte boundaries.
