Which one of the following is not an application software?
- A.Spreadsheet
- B.AutoCAD
- C.MS PowerPoint
- D.Linker
Correct answer
Explanation
The correct answer is D, Linker. A linker is system software, a programming tool that joins compiled pieces of code into one program that can run; it does not do a task for the end user.
Software is broadly divided into system software and application software. System software runs the computer and supports other programs: operating systems, device drivers, utilities, and language translators such as compilers, assemblers and interpreters, along with the linker and loader. When a program is compiled, each source file becomes an object file; the linker combines these object files and library code into a single executable, and the loader then places it in memory to run. Application software, by contrast, helps the user do a particular job, such as writing, calculating, drawing or presenting.
Option A is wrong because a spreadsheet such as MS Excel is application software for calculations. Option B is wrong because AutoCAD is application software for design and drafting. Option C is wrong because MS PowerPoint is application software for presentations.
Exam tip: compiler, assembler, interpreter, linker, loader = system software; Word, Excel, PowerPoint, AutoCAD = application software.
