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

The primary function of the CPU, or Central Processing Unit, in a computer system is to perform calculations and execute instructions. The CPU is often referred to as the "brain" of the computer because it processes data and carries out tasks defined by programs. It does this by executing a sequence of stored instructions known as a program.

When a program is run, the CPU interprets and processes the instructions, which may involve arithmetic operations, logic operations, controlling the flow of data, and coordinating the activities of other hardware components. This makes the CPU essential for the overall functionality of the computer, as it translates user commands into actions performed by the machine.

The other functions provided in the options describe roles that are indeed part of a computer system but are not the primary focus of the CPU. Managing hardware resources involves operating systems and other components that handle the allocation and scheduling of resources among various hardware parts. Storing data permanently relates to storage devices, such as hard drives and SSDs, which are responsible for data retention. Connecting various components of the computer is handled by the motherboard and related circuitry, which facilitate communication between the CPU, memory, and peripheral devices.
