Computer program

A computer program is an organized set of instructions that a computer can execute to perform tasks or produce results.

Programming language: A formal language used to express instructions and data structures for computation. Programs are written in programming languages that define their syntax and meaning.
Compiler: A program that translates source code into another form, often machine code. A compiler can transform a program before it runs.
Application software: Software designed to help users perform particular tasks. Computer programs commonly appear as applications for direct user tasks.
Computer software: Programs and associated data, documentation, and procedures used by computer systems. Software is the broader category that includes programs and their supporting materials.
Algorithm: A finite, precise procedure for solving a problem or performing a computation. An algorithm describes the procedure a program implements.
Interpreter (computing): A program that executes instructions from a source representation, often without producing a standalone executable. Interpreters provide an alternative to ahead-of-time compilation.
Web application: Application software accessed through a web browser, usually using a network connection. Web applications are programs delivered through browser-based interfaces.
Computer hardware: The physical components of a computer system, including processors, memory, and devices. Programs are instructions; hardware is the physical machinery that executes them.
Data structure: A way of organizing data so software can access and modify it efficiently. Programs use data structures to represent and manipulate information.
Machine code: Instructions encoded in a processor's native binary format. A processor directly executes machine-code programs.
