A computer application, often known as an application program, is a piece of software that runs on your computer. Examples of apps include web browsers, e-mail programs, word processors, games, and utilities. Because each piece of software has its own application for the user, the term “application” is employed. A word processor, for example, can assist a student in writing a research paper, but a video game can impede the student from finishing the work.

On the other hand, system software consists of programs that operate in the background and allow apps to execute. Assemblers, compilers, file management tools, and the operating system itself are among these applications. Because the system software is made up of “low-level” programs, applications are said to run on top of it. While system software is pre-installed with the operating system, you may choose which programs to install and use on your computer.
