Which of the following is NOT an example of application software?

A. Internet Explorer web browser

B. Photoshop image editing program

C. Windows operating system

D. Microsoft PowerPoint presentation software

Answer: –C. Windows operating system

The correct answer is ‘DOS’. DOS is an operating system, not an application software. Application software is a program or group of programs designed for end users. They can be used for a variety of purposes, including word processing, spreadsheets, and computer graphics. Operating systems, on the other hand, are system software that provide a platform for other software to run on. They manage the computer’s resources, such as the CPU, memory, and storage.
