What is the main role of the CPU in a computer system?

The main role of the CPU, or Central Processing Unit, in a computer system is to perform calculations and execute instructions. The CPU acts as the brain of the computer, interpreting and processing instructions from programs and carrying out the necessary calculations to perform tasks. It handles operations such as arithmetic calculations, logic operations, and control tasks that are essential for the functioning of both the operating system and applications.

While data storage is a crucial component of a computer system, it is primarily managed by storage devices like hard drives and SSDs rather than the CPU itself. Connecting to external devices is typically handled by peripheral components and interfaces, rather than directly by the CPU. Network traffic management is performed by networking hardware and software, with the CPU executing instructions related to these tasks but not managing traffic directly. Overall, the CPU is fundamental for executing instructions and performing the necessary computations critical for running software and managing tasks within a computer system.
