In computer programming, a module is defined as a collection of one or more routines. Then the modules combine to make a program.
Modules make it easier for a programmer to concentrate on a specific part of a program as these modules can further be reused for enhancement of a project or say updating process.
Modules have evolved the problem of reusing already written code as in previous times, when the software of applications needed to update they were taken from a very basic level but now modules make it possible to reuse the already written code as many times as needed.
