The central processing unit (CPU) is the primary component responsible for processing data in a computer. It executes instructions from programs and manages the operations of the computer hardware. The CPU performs arithmetic and logic calculations and controls data flow in the system, making it crucial for executing program code and performing tasks.

While other components play important roles in a computer system, they do not directly handle data processing in the same way the CPU does. The hard drive is responsible for data storage, while RAM serves as temporary storage that provides quick access to data that the CPU needs while running programs. The motherboard connects all the components, allowing them to communicate, but it does not itself process data.
