How many bits does a typical 8-bit CPU register hold?a. 4 bitsb. 8 bitsc. 16 bitsd. 32 bits

Break Down the Problem

1. Understanding CPU Registers: A CPU register is a small amount of storage available directly in the CPU for quick storage and retrieval of data.
2. Defining 8-Bit CPU Register: The term "8-bit CPU register" indicates the size of the register.

Relevant Concepts

1. An 8-bit register can hold $2^8 = 256$ different values.
2. Each bit in a binary system represents a binary digit (0 or 1).

Analysis and Detail

1. Since the register is specified as 8-bit, it directly implies its capacity.
2. The options provided relate to the definition of the register size.

Verify and Summarize

• The register size stated is 8 bits.
• The options include values larger and smaller than the given register size.

Final Answer

The correct answer is b. 8 bits.
