program

A program is a sequence of instructions that a computer follows to perform a specific task. It can be written in various programming languages, such as Python, Java, or C++, and is executed by a computer's processor. Programs can range from simple scripts that automate repetitive tasks to complex applications that manage large databases or control hardware devices.

Programs are typically created using a development environment, which provides tools for writing, testing, and debugging code. They can be compiled into machine code, which is the native language of a computer's processor, or interpreted by a software interpreter, which executes the code directly.

Programs can be categorized into different types based on their functionality. System programs manage the computer's hardware and software resources, while application programs perform specific tasks for users, such as word processing or web browsing. Utility programs provide additional functionality, such as file compression or data encryption.

Programs can also be categorized based on their distribution model. Open-source programs are freely available and can be modified and distributed by anyone, while proprietary programs are owned by a company and are subject to licensing restrictions.
