when it is passed by reference
When a module is called, the computer jumps to that module and executes the statement in the module's body. Then, when the end of the module is reached, the computer jumps back to the part of the program that called the module, and the program resumes execution at that point.End

This piece of data is called an "argument".
A module is not an executable but, depending on the type of module, it may contain executable code. To invoke that code, you will generally need to execute a machine-code program that can interpret the code within the module. Without knowing the specifics of the module in question, it is impossible to determine how any code within it may be executed.

Yes, when passing an argument by reference, changes to the argument made within the module will directly affect the original variable in the calling part of the program. This is because the reference to the original variable's memory address is passed to the module, allowing it to modify the variable directly.
Declaring,defining and calling function
If a module is the sole possessor of a value, it will be passed by value, meaning a copy of the argument will be made and used within the module. This copy will be modified independently of any other modules or the original value.
