Final answer:
The primary function of the Central Processing Unit (CPU) in a computer is to perform calculations and execute instructions. It acts as the brain of the computer, controlling all the other components and processes.
Step-by-step explanation:
The CPU interprets and executes instructions from the computer's memory, performs arithmetic and logical operations, and manages data flow between different parts of the computer system.
For example, when you open a web browser, the CPU receives the instruction to launch the program, retrieves the necessary data and instructions from the computer's memory, and executes the instructions to display the web page.
It performs millions or even billions of calculations per second to ensure smooth and efficient operation of the computer.
Without the CPU, a computer would not be able to perform any tasks or run programs. It is a vital component that enables the computer to process information and carry out various functions.
