Which component is described as the heart and brain of a computer?

The Central Processing Unit (CPU) is often referred to as the heart and brain of a computer because it is responsible for executing instructions and processing data. The CPU performs the essential calculations and logical operations that enable all other components of the computer to function effectively. It interprets and executes program instructions, managing tasks and processes that allow software applications to run.

In this context, the CPU coordinates the activities of memory, input, and output devices, and all software applications rely on its processing power to function. Without the CPU, a computer would not be able to perform any meaningful tasks, highlighting its critical role in computing operations.

While other components such as RAM, the motherboard, and the GPU play important roles in a computer system, they operate in support of, or in tandem with, the CPU. For instance, Random Access Memory (RAM) temporarily stores data and instructions that the CPU needs while processing, but it does not perform any calculations on its own. The motherboard serves as the main circuit board, connecting all components but does not execute program instructions. The Graphics Processing Unit (GPU) specializes in rendering images and video but is not involved in the general processing of instructions. Therefore, the CPU's central role in executing and processing makes it the heart
