Brain of the computer that performs instructions defined by software.

Brain of the computer that performs instructions defined by software.

• A. Graphics Processing Unit (GPU)
• B. Memory
• C. Central Processing Unit (CPU)
• D. RAM

Answer: (C)

The brain of the computer is the device that actually runs the program by executing the instructions defined by software. The Central Processing Unit carries out those instructions, fetching them from memory, decoding what needs to be done, and performing the required operations—arithmetic, logic, and control tasks. It also coordinates the actions of other components, acting as the system’s control center. A Graphics Processing Unit specializes in parallel processing for graphics tasks, not general-purpose instruction execution, while memory like RAM stores data and instructions for quick access but does not execute them by itself.
