How many R-S flip-flops are needed to create an 8-bit storage register?

• A. 4
• B. 6
• C. 8
• D. 10

Answer: (C)

The correct answer is based on the fact that each R-S flip-flop can store one bit of information. Therefore, to create an 8-bit storage register, you would need a total of 8 R-S flip-flops, one for each bit. This allows the register to hold and manipulate 8 distinct binary digits, which collectively represent values ranging from 0 to 255 in decimal form. Each flip-flop corresponds directly to a single bit in the register, thereby requiring a one-to-one ratio for proper data storage. While the other options indicate different numbers of flip-flops, they do not meet the requirement to form an 8-bit register. Understanding this relationship between bits and the number of flip-flops is crucial in digital electronics and computing hardware design.
