loader 

Loader can be defined as-
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.

By program here, we mean a binary file that is the result of a programming language compilation, linkage editing, or some other program preparation process.

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. Some embedded operating systems in highly specialized computers run only one program and have no program loading capabilities and thus no loaders, for example embedded systems in cars or stereo equipment.

In computing, a 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. The loader is usually a part of the operating system's kernel and usually is loaded at system boot time and stays in memory until the system is rebooted, shut down, or powered off. Some operating systems that have a pageable kernel may have the loader in the pageable part of memory and thus the loader sometimes may be swapped out of memory. All operating systems that support program loading have loaders. Some embedded operating systems in highly specialized computers run only one program and have no program loading capabilities and thus no loaders, for example embedded systems in cars or stereo equipment. In Unix, the loader is the handler for the system call execve().
