Message passing relies on the process and its supporting organization to call the actual code to run. The difference between conventional programming calls by the fact that usual programming procedure calls the process by name instead of a data packet or signal trigger. It is basically communication between two processes, subroutines, or functions within a program. Modern computer software largely uses message passing to implement efficient programming techniques. In networks such as the Internet, where objects may also be working from various computers, the process of message passing plays an important role. Channels are an efficient way to implement message passing in modern systems.
