There are two major phases of compilation, which in turn have many parts. Then loader loads it in memory and executes it. Linker loads a variety of object files into a single file to make it executable.

Loader/Linker – It converts the relocatable code into absolute code and tries to run the program resulting in a running program or an error message (or sometimes both can happen).The address within the program will be in such a way that it will cooperate with the program movement. Relocatable Machine Code – It can be loaded at any point and can be run.Interpreted programs are usually slower with respect to compiled ones. Compiler scans the entire program and translates it as a whole into machine code whereas an interpreter translates the program one statement at a time. The Compiler in one go reads the inputs, does the processing, and executes the source code whereas the interpreter does the same line by line. But they are different in the way they read the input. Interpreter – An interpreter converts high-level language into low-level machine language, just like a compiler.Its translates assembly language to machine code. The output of the assembler is called an object file. They are not universal since for each platform we have one. Assembler – For every platform (Hardware + OS) we will have an assembler.It is an intermediate state that is a combination of machine instructions and some other useful data needed for execution. Assembly Language – It’s neither in binary form nor high level.It performs file inclusion, augmentation, macro-processing, etc. Pre-Processor – The pre-processor removes all the #include directives by including the files called file inclusion and all the #define directives using macro expansion.They direct the pre-processor about what to do. These (#) tags are called preprocessor directives. They are closer to humans but far from machines. High-Level Language – If a program contains #define or #include directives such as #include or #define it is called HLL.This is where language procedure systems come in handy.

Now, these programs go through a series of transformations so that they can readily be used by machines. The hardware knows a language, that is hard for us to grasp, consequently, we tend to write programs in a high-level language, that is much less complicated for us to comprehend and maintain in thoughts.

We know a computer is a logical assembly of Software and Hardware. Language processing systems (using Compiler) – Source-to-source Compiler or transcompiler or transpiler is a compiler that translates source code written in one programming language into the source code of another programming language.It is capable of creating code for a platform other than the one on which the compiler is running. Cross Compiler that runs on a machine ‘A’ and produces a code for another machine ‘B’.The compiler is software that converts a program written in a high-level language (Source Language) to low-level language (Object/Target/Machine Language).
