What comes first linker or loader?

Compiler It converts the source code into the object code. Linker It combines the multiple object files into a single executable program file. Loader It loads the executable file into main memory.

What is the use of linker and loader?

The main function of Linker is to generate executable files. Whereas main objective of Loader is to load executable files to main memory. The linker takes input of object code generated by compiler/assembler. And the loader takes input of executable files generated by linker.

What is linker loader assembler and compiler?

A compiler is a program that converts high-level language to assembly language. An assembler then translates the assembly program into machine code (object). A linker tool is used to link all the parts of the program together for execution (executable machine code).

What is the use of compiler and linker in a program?

For most compilers, each object file is the result of compiling one input source code file. When a program comprises multiple object files, the linker combines these files into a unified executable program, resolving the symbols as it goes along.

What is the purpose of the loader?

In computer systems a loader is the part of an operating system that is responsible for loading programs and libraries. It is one of the essential stages in the process of starting a program, as it places programs into memory and prepares them for execution.

What is Assembler compiler?

Assembler. Compiler converts the source code written by the programmer to a machine level language. Assembler converts the assembly code into the machine code. Compiler input source code. Assembler input assembly language code.

What is program relocation how relocation is performed by linker explain with example?

Relocation of Linking Concept • Program relocation is the process of modifying the addresses used in the address sensitive instruction of a program such that the program can execute correctly from the designated area of memory. • If linked origin≠ translated origin, relocation must be performed by the linker.
