Which one of the following is not an application software?

The correct answer is Linker.

Key Points

• A Linker is classified as a system software, not an application software.
• System software like Linker is used to manage and control computer hardware and serves as a platform for other software.
• The primary function of a Linker is to combine multiple object files (produced by the compiler) into a single executable file.
• Application software, on the other hand, includes programs designed for end-users, such as spreadsheets (e.g., MS Excel), presentation tools (e.g., MS PowerPoint), and design software (e.g., AutoCAD).
• Linkers are essential in software development and programming but do not directly serve end-user tasks or applications.

Additional Information

• Application Software:
  • Application software is designed to help users perform specific tasks, such as word processing, spreadsheet management, and graphic design.
  • Examples include MS PowerPoint, MS Excel, AutoCAD, web browsers, and media players.
  • Application software is user-oriented and directly interacts with the end-user.
• System Software:
  • System software acts as an intermediary between hardware and application software.
  • Examples include operating systems (e.g., Windows, Linux), compilers, and linkers.
  • System software is primarily designed for managing system resources and enabling the functionality of application software.
• Linker:
  • A linker is a system software tool used in programming to combine object files into a single executable file.
  • It resolves references between different modules and ensures the program runs correctly.
  • Linkers are a critical part of the software development process, typically used in languages like C, C++, and assembly.
• Compiler:
  • A compiler is another system software used to translate high-level programming code into machine code.
  • It works alongside the linker to create executable programs.
  • While compilers convert source code into object code, linkers bring together multiple object code files.
