Final answer:
A computer program provides instructions that tell a computer what to do.
Step-by-step explanation:
A computer program provides the instructions that tell a computer what to do. It is a sequence of instructions that are written in a programming language such as Python, Java, or C++. These instructions can be simple or complex, and they guide the computer in performing specific tasks.
For example, if you want to create a program that adds two numbers, you would write the instructions to take input from the user, perform the addition operation, and display the result. The computer program is what enables the computer to execute these steps and provide the desired output.
