Object Module

An object module is a compiled unit of code that contains executable instructions, data, and other resources necessary to perform a specific task or function. It is a standalone unit of code that can be linked with other modules to create a complete program. Object modules are used in software development to break down a large program into smaller, more manageable parts, making it easier to test, debug, and maintain.

Object modules are created by compiling source code written in high-level programming languages such as C, C++, Java, and Python. The compiler translates the source code into machine code that can be executed by the computer’s processor. The resulting object module contains the machine code, as well as any data or resources that are required by the program.

Object modules can be linked together to create a complete program. The linker is a tool that combines multiple object modules into a single executable file. During the linking process, the linker resolves any references between the modules, ensuring that all the necessary functions and data are available to the program.

Object modules are often used in software development to create reusable code libraries. A library is a collection of object modules that can be linked with other programs to provide common functionality. Libraries can save development time and reduce the risk of errors by providing tested and reliable code that can be used across multiple projects.

In summary, an object module is a compiled unit of code that contains executable instructions, data, and other resources necessary to perform a specific task or function. It is a fundamental building block in software development that allows developers to create complex programs by combining smaller, more manageable parts.
