Which component is NOT part of the CPU?

The Graphics Processing Unit (GPU) is indeed not part of the Central Processing Unit (CPU). The CPU is primarily responsible for executing instructions from computer programs and consists of several key components: the Control Unit, which directs the operation of the processor, and the Arithmetic/Logic Unit (ALU), which performs mathematical and logical operations. Cache Memory, while not a CPU core, is closely associated with the CPU as it helps to speed up data access by storing frequently used data and instructions.

The GPU, on the other hand, is a separate processor designed specifically for rendering graphics and performing parallel processing tasks. It operates independently of the CPU and is optimized for tasks such as image rendering, video playback, and complex calculations in graphics tasks. This distinction is essential in understanding the architecture and functioning of computers, as it highlights the specialized roles that different components play in overall system performance.
