Q1: When used with an IC, what does the term "QUAD" indicate?

ANS:B - 4 circuits

A quad (pronounced KWAHD) is a unit in a set of something that comes in four units. The term is sometimes used to describe each of the four numbers that constitute an Internet Protocol (IP) address. Thus, an Internet address in its numeric form (which is also sometimes called a dot address) consists of four quads separated by "dots" (periods).
