at various sales brochures advocating various types of memory. What would be one advantage to
buying dual-channel memory?

A.
It will reduce memory bottlenecks.

B.
It will be twice as fast as single channel memory.

C.
It has no advantage over single channel memory.

D.

or capacity.
Answer option C is incorrect. It will have an advantage over single channel, though the advantages
are slight.
