Q. Define Point-to-point Communication?
The simplest form of message is a point to point communication. A message is sent from the transmitting processor to a receiving processor. Message passing in point-to-point communication can be in any 2 modes: asynchronous and synchronous. In synchronous transfer mode the next message is sent just after the acknowledgement of delivery of the last message. In this mode sequence of messages is managed. In asynchronous transfer mode no acknowledgement for delivery is needed.
