Answer 2

The software includes process management, memory management, I/O control, and file management. This Layer or class includes compilers, assemblers, linkers, etc.

Assembler:

• The assembler is used to translate a program written in assembly language into machine code.
• The source program is an assembly language compiler entry that contains assembly instructions.
• The output generated by the assembler is object or machine code that can be understood by a computer.

Compiler:

• A language processor that reads the entire source program written in a high-level language at once and translates it into an equivalent program in machine language is called a compiler. Eg:C, C++, C#, Java
• In the compiler, the source code is successfully translated into object code if it has no errors.
• The compiler specifies the error at the end of the compilation with the line number when there is an error in the source code. Errors must be eliminated before the compiler can successfully recompile the source code.

Linker:

• The linker is a special program that combines object files, generated by assembler/compiler, and other pieces of code to generate executables are there. exe extension.
• In the object file, the linker finds and adds all the libraries needed to run the file. It specifies the memory space that each module's code will contain.
• It also merges two or more separate object programs and establishes a link between them.
