Explanation

Central Processing Unit (CPU) The CPU is the brain of a computer, containing all the circuitry needed to process input, store data, and output results. The CPU is constantly following instructions of computer programs that tell it which data to process and how to process it.

The computer brain is a microprocessor called the central processing unit (CPU). The CPU is a chip containing millions of tiny transistors. It's the CPU's job to perform the calculations necessary to make the computer work -- the transistors in the CPU manipulate the data.

A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions.

The component of a computer system that controls the interpretation and execution of instructions. The CPU of a PC consists of a single microprocessor, while the CPU of a more powerful mainframe consists of multiple processing devices, and in some cases, hundreds of them.

The central processing unit (CPU) guides the computer through the various steps of solving a problem. Data enters the computer through an input unit, is processed by the central processing unit, and is then made available to the user through an output unit.

There are mostly three types of CPU.

Single core CPU: This have a single core which is used to processing data. this is the oldest CPU. This performs a single task at a time.
Dual Core CPU: This CPU have two core and a single Integrated Circuit.
Quad Core CPU: This CPU have two Dual Core and a single Integrated Circuit.

Uses of CPU:-

CPU perform logic, control, arithmetic, input and output operations specified by its programming to perform basic tasks. They're found in most electronic devices, including laptop computers, smartphones, some cameras, thermostats and any other type of device that requires input and output programming operations.

Hence, the correct option is C.
