Differce between linker and loader

Answer 1

#)Linker is a program that takes one or more objects generated by a compiler and combines them into a single executable program.

#)Loader is the part of an operating system that is responsible for loading programs from executables (i.e., executable files) into memory, preparing them for execution and then executing them.

Answer 2

• linker which linkes the files whereas lodar which loads the file after linking .
• linkers takes independently translated programs as input whose original source language representations includes symbolic refrences to each other whereas loaders accept object program, prepare these programs for execution by computer and initiate the execution

Answer 3

Answer 4

LINKERS:-

Linkers are the system softwares that are used to link the functions,resources to their respective references.

EX-

source code(.c) is compiled and converted into object code(.obj) in C.

After this Linker comes into the act, linker resolve all the references in .obj file via linking them to their respectives codes and resources.In short linker performs the final step to convert .obj into executable or machine readable file(.exe).

eg:

#include<stdio.h>

int main()

{

printf("ashwin");

return 0;

}

here,compiler first searches the declaration for "printf()" function,finds it in "#include<stdio.h>" and creates a (.obj) file successfully.

A symbol table is created in (.obj) file which contains all the references to be resolved,linkers resolves them by providing respective code or resource,

here code referred by "printf" also gets executed after successful creation of( .exe) file by linker.

LOADERS:

Loaders are the programs that are used to load the resources like files from secondary or main memory,i.e.

SUMMARY:

Loader loads the referred resource or file after being Linked to referrer via a Linker during the execution of program.

HAAHAHAHAHHAHAHAH I HAVE FOOD AND YOU Don't HAHHAHAHAHAHAHA HAHAHAHAHHAAHHAAHAHAHHAAHHAHA

Answer 6

A compiler converts high-level code into object files, a linker links together these object files into a single executable
