What do you mean by binding of data and functions?

Explanation

  • Data binding is the process of binding the data objects used by the program with the actual physical memory.

  • Two types of binding.

  • Early binding

    • The process of binding the data objects and the physical memory at compile time.

    • The memory is allocated to the data object when the application is loaded into the memory for execution.

  • Late binding

    • The process of associating memory to the objects at run-time, when these objects are dynamically created.

    • Minimal memory is bound to these objects as these are pointers.
