In the context of computer networks, what is a key function of the CPU?

The key function of the CPU (Central Processing Unit) is to process user commands and instructions. The CPU is often referred to as the "brain" of the computer because it executes the instructions from programs and performs calculations, logical operations, and data handling. This processing capability allows the computer to perform tasks and run applications effectively, responding to user inputs and executing complex operations.

While assigning IP addresses and coordinating data packet transmission are crucial tasks in network management, these responsibilities are typically handled by network devices like routers and servers, rather than the CPU itself. Similarly, developing network security protocols is primarily the domain of software engineers and cybersecurity professionals who design systems and protocols to protect network communications, which is also distinct from the CPU's core function. Thus, processing user commands and instructions stands out as the primary role of the CPU in a computer system.
