Knowra Application software Application software Application software helps users perform tasks such as writing documents, managing data, or communicating. It runs on system software and is distinct from software that manages hardware or provides shared services.
Operating system : System software that manages computer hardware and provides services and interfaces for programs. Applications rely on its services to access files, memory, devices, and networks.
Word processor : An application for creating, editing, formatting, and printing text documents. It is a familiar application type centered on producing written documents.
System software : Software that manages computer hardware or provides a platform for other software. Unlike application software, it primarily supports the computer's operation and other programs.
Executable file : A file containing instructions that a computer can execute as a program. Desktop applications are commonly launched from executable files or packages containing them.
Open-source software : Software distributed under a license that grants access to its source code and specified rights to use, modify, and share it. Open-source licensing enables application code to be inspected, adapted, and redistributed under its terms.
Application programming interface : A defined interface through which software components or services communicate. APIs let applications use operating-system services and connect to other software.
Spreadsheet : An application that organizes data in cells and supports calculations, analysis, and visualization. It applies software to tabular data, formulas, and quantitative analysis.
Utility software : Software that performs maintenance, configuration, or protective tasks for a computer system. Utilities often serve system upkeep rather than a user's primary productive task.
Software installation : The process of placing and configuring software so it can run on a computer. Installation makes an application available and may configure dependencies, settings, and system integration.
Proprietary software : Software whose use, modification, or redistribution is restricted by its owner or license. Proprietary terms commonly limit how an application may be copied, changed, or shared.
