What is the difference between linker and loader

I stayed at home. In this example, we can see that the first idea, 'It was raining. A linker usually performs relocation in conjunction with symbol resolution, the process of searching files and libraries to replace symbolic references or names of libraries with actual usable addresses in memory before running a program.

Linking is the process of collecting and combining various pieces of code and data into a single file that can be loaded copied into memory and executed. On modern systems, linking is performed automatically by programs called linkers. 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.

Linking is the final step of compilation. The linker merges all the object code from multiple modules into a single one. The Source code of a program passes through compiler, assembler, linker, loader in the respective order, before execution. On the one hand, where the linker intakes the object codes generated by the assembler and combine them to generate the executable module.

On the other hands, the loader loads this executable module to the main memory for execution. Let us discuss the difference between Linker and loader with the help of a comparison chart. It loads the executable module to the main memory. Input It takes as input, the object code generated by an assembler.

It takes executable module generated by a linker. Function It combines all the object modules of a source code to generate an executable module.

It allocates the addresses to an executable module in main memory for execution. Absolute loading, Relocatable loading and Dynamic Run-time loading. The Assembler generates the object code of a source program and hands it over to the linker. The linker takes this object code and generates the executable code for the program, and hand it over to the Loader.

The high-level language, programs have some built-in libraries and header files. Viva Differences. Linker A linker is a computer program that takes one or more objects generated by a compiler or an assembler and combines them into a single executable program. A linker is a computer program that takes one or more objects generated by a compiler and combines them into a single executable program.

The loader is the part of an operating system that is responsible for loading programs from executable files into memory, preparing them for execution and then executing them. Loader can be of three types: Absolute loading, Relocatable loading and dynamic run-time loading. Loader is responsible for adjusting references which are used within the program.

The linker links the object code and the header files and outputs the executable file. The linker combines all object module of a program to generate executable modules it also links the library function in the object module to built-in libraries of the high-level programming language.
