What is the main function of the CPU?

• A. Store data permanently
• B. Execute instructions from programs
• C. Connect to the internet
• D. Provide user interface

Answer: (B)

The main function of the CPU, or Central Processing Unit, is to execute instructions from programs. This involves processing data and performing calculations or logical operations as directed by the software running on the computer. The CPU interprets and carries out the commands provided by the software, effectively serving as the brain of the computer. While storing data is essential, it is primarily the function of memory or storage devices, not the CPU. Connecting to the internet is a task managed by network interfaces, rather than the CPU itself, which focuses on processing tasks. Lastly, providing a user interface is typically the role of software systems and graphical interfaces, not the CPU. Thus, executing instructions is the CPU's central role, driving all computational tasks performed by the machine.
