what is load module

Load module is a term that is commonly used in computer programming. However, many people are still unaware of what it really means. In simple terms, a load module is a file that contains executable code. It can be used by a program to perform specific functions. This article will provide a comprehensive explanation of what load modules are and how they work.

What Are Load Modules?

A load module is a binary file that contains executable code. It is created by compiling source code written in a programming language such as COBOL, C, C , or Java. Once the source code is compiled, the resulting file is known as an object file. The object file can then be linked with other object files to form a load module. The load module is the final executable code that can be loaded and executed by a computer.

The Significance of Load Modules

Load modules play a crucial role in computer programming. They are used to provide the actual functionality of an application. Without load modules, a program would simply be a text file containing human-readable code. Load modules make it possible for a program to be executed on a computer. They also make it possible to distribute and install software applications on multiple computers.

Types of Load Modules

There are two main types of load modules: dynamic load modules and static load modules. A static load module is created by linking all the required object files together at compile time. The final executable code is generated and saved as a file that can be loaded and executed. A dynamic load module, on the other hand, is linked at runtime. This means that the required object files are loaded on demand. This makes it possible to dynamically load and unload modules as needed.

Conclusion

In conclusion, load modules are essential components of computer programming. They are used to provide the actual functionality of a program. Load modules help to make it possible to distribute and install software applications on multiple computers. There are two main types of load modules - static load modules and dynamic load modules. Both types play important roles in computer programming and are used extensively in software development.
