A computer program is a set of instructions that a computer can execute to perform a specific task or solve a problem. Programs are written in a specific programming language, which is a set of rules and syntax that defines how the instructions should be written.
Computer programs can be as simple as a single line of code that prints a message to the screen, or as complex as a multi-million line software application that performs a variety of tasks. Programs can be used to perform a wide range of tasks, such as calculating numbers, organizing and storing data, creating and editing documents, and running simulations.
There are many different types of computer programs, including:
- System software: This type of software is responsible for managing the hardware and software resources of a computer. Examples include operating systems, device drivers, and utilities.

- Mobile apps: These are programs that are designed to run on mobile devices, such as smartphones and tablets. Examples include games, productivity tools, and social media apps.
Computer programs are an essential part of modern life, as they are used to perform a wide range of tasks and solve many different problems.
