What is the primary function of the CPU in a computer system?

The primary function of the CPU (Central Processing Unit) in a computer system is indeed processing information. The CPU acts as the brain of the computer, executing instructions from programs, performing calculations, and managing data flow between different parts of the system.

When a program is run, the CPU interprets and executes the commands, handling both arithmetic and logical operations. This core functionality allows the CPU to take inputs, process them, and produce outputs, making it essential for overall system operation.

While storing data, inputting commands, and outputting results are all important aspects of a computer system, they are not functions of the CPU itself. Data storage is typically handled by RAM or storage devices, input commands come from peripheral devices (like keyboards or mice), and outputs are sent to display devices or other output hardware, but all these processes rely on the CPU for coordination and execution. Thus, processing information is the key role that defines the CPU's primary function within a computer system.
