S OFTWARE Software: Software is a set of programs Mr. Mohammed Rahmath

1. A PPLICATION SOFTWARE Definition: Application software, also known as an application or an "app", is computer software designed to help the user to perform specific tasks. Example: MS word, MS Excel, MS PPT, etc… Mr. Mohammed Rahmath

2. S YSTEM S OFTWARE Definition: Computer software, or just software is a general term primarily used for digitally stored data such as computer programs and other kinds of information read and written by computers. App comes under computer software though it has a wide scope now. Example: OS,Utilities, Windows Mr. Mohammed Rahmath

Application Software Computer/ System Software Interaction: Users always interact with application software while doing different activities. Generally, users do not interact with system software as it works in the background. Dependency: Application software cannot run without the presence of the system software. System software can run independently of the application software. Mr. Mohammed Rahmath
