What is the function of marshaling and un-marshaling process?Answer :Allows programs to call procedures located on other machines.Creating a stub for sending and receiving messages.Allowing application to integrate.Converting data values from their local representation to a network format and on to the remote representation.

Marshaling and unmarshalling processes serve several important functions in distributed systems and programming:

1. Remote Procedure Call (RPC): Marshaling allows programs to call procedures located on other machines. This is done by packaging or 'marshaling' the input parameters so that they can be sent over the network.

2. Stub Creation: Marshaling involves creating a 'stub' or a piece of code that stands in for the remote procedure. This stub is responsible for sending and receiving messages.

3. Application Integration: Marshaling and unmarshalling processes allow different applications to integrate and communicate with each other, even if they are written in different programming languages or running on different platforms.

4. Data Conversion: Marshaling involves converting data values from their local representation to a network format. This is necessary because different systems may represent data in different ways. After the data reaches its destination, it is 'unmarshalled' or converted back into the format that the remote system can understand.
