What is the primary role of the Central Processing Unit (CPU) in a computer system?
To execute program instructions
The Central Processing Unit is the main processing hardware of a computer, often called its brain.
Its core job is to fetch each instruction of a program from memory, decode it and then execute it, carrying out arithmetic, logic and control operations.
Managing network connections is handled by network hardware, displaying output is the monitor's task, and long-term storage is done by drives — none of these is the CPU's primary role.
Hence, the answer is To execute program instructions.
