4.What does a message in Inter process Communication consist?     Clear ResponseHeader a & bFrame

A message in Inter Process Communication (IPC) typically consists of the following components:

1. Header: This is the initial part of the message that contains information about the message itself, such as its length, destination, source, etc. It is used by the system to understand how to process the message.

2. Body: This is the main part of the message that contains the actual data or information that needs to be communicated between the processes.

3. Frame: This is the structure that encapsulates the header and the body of the message. It provides a way to organize and manage the message as a single unit.

So, the correct answer would be "a & b" as both Header and Frame are parts of a message in IPC.
