well vishal, In a computer operating system , a loader is a component that locates a given program (which can be an application or, in some cases, part of the operating system itself) in offline storage (such as a hard disk ), loads it into main storage (in a personal computer, it's called random access memory ), and gives that program control of the computer (allows it to execute its instruction s).
A program that is loaded may itself contain components that are not initially loaded into main storage, but can be loaded if and when their logic is needed.
In a multitasking operating system, a program that is sometimes called a dispatcher juggles the computer processor's time among different tasks and calls the loader when a program associated with a task is not already in main storage. this is taken from source http://whatis.techtarget.com/d efini tion/0,,sid9_gci212493,00.html
