What is the role and purpose of an entry point in software or a system?

The entry point in software is the location where the execution of a program or system begins.

It determines which code or process is launched first and sets the initial logic of the application. For example, in programming languages, this could be the main() function, and in web applications, it could be the main script or route that handles the first request.

The role of the entry point:

• Initialization of necessary resources and settings.
• Starting the main loop or logic of the application.
• Managing control transfer between components.

Without a clearly defined entry point, the system will not be able to start correctly, as it will be unclear where to begin execution.
