Which components are part of typical CPU architecture?

The choice that includes the Register, Arithmetic Logical Unit (ALU), Control Unit (CU), and Cache accurately reflects the fundamental components of typical CPU architecture.

The Register is a small-sized type of volatile computer memory that provides high-speed data storage and access to the CPU, making it essential for the processor's operations. The ALU is a critical part of the CPU that handles all arithmetic and logical operations, directly influencing the CPU's computing power. The Control Unit orchestrates the actions of the CPU, directing data flow between the ALU, registers, and other components, as well as controlling the execution of instructions. Lastly, Cache memory is a smaller, faster type of volatile memory located inside or very close to the CPU, allowing for quick access to frequently used data and instructions, which significantly enhances processing speed.

The other choices contain components that are either not directly part of the CPU or include incorrect combinations. For instance, while memory devices such as RAM and hard drives are vital to a computer system, they are not part of the CPU architecture itself. Similarly, while the mention of graphics cards is important in a computer's overall architecture, they fall outside the definition of CPU components. Therefore, choice B best encapsulates the core elements that constitute CPU
