Q1. Which of the following is system software?
Explanation
System software manages computer hardware and provides a platform for application programmes. Linux is an operating system, so it directly controls hardware resources, files, memory, processes and user access. Excel is a spreadsheet application used for calculations and tabular work. Power point is presentation software used to prepare slides. MS word is a word-processing application used to create and edit documents. These three are application software because they perform user-specific tasks, while Linux belongs to the system software category.
