Question

what does not apply to the system software?​

Answer 1

Such software is not considered system software when it can be uninstalled usually without affecting the functioning of other software. Exceptions could be e.g. web browsers such as Internet Explorer where Microsoft argued in court that it was system software that could not be uninstalled.

Answer 2

Compilers not apply to the system software.

• Compilers Software used for applications is NOT system software. A piece of software called a compiler transforms source code written in a high-level programming language into machine code suitable for a specific computer architecture.
• The source code of one programming language is converted into machine code, bytecode, or another programming language by a compiler, a specialised programme. Usually, a high-level, understandable language like Java or C++ is used to create the source code.
• A piece of software called a compiler converts source code written in high-level programming languages into machine code. Without altering its meaning, it converts code written in one computer language into another. The compiler also improves the performance and memory use of the final code.
• Compilers are pieces of software that change source code into object code. It translates high-level language to machine/binary language, to put it another way. This step must be completed in order for the programme to be executable. This is because only binary language is understood by the computer.
