What types of differences exist between a framework and a library in software development?

The main difference between a library and a framework lies in the control over the flow of program execution:

• Library is a set of functions and classes that the developer calls as needed. You control when and how to use the library.
• Framework is the application skeleton that sets the structure and flow of execution. You write code that is called by the framework (inversion of control).

Example:

• Using a library: you call a function from the library to process data.
• Using a framework: you create handlers or components, and the framework calls them at the appropriate time.

Thus, the framework dictates the architecture of the application, while the library provides tools to solve tasks.
