Question

3. Define the message format, structure and semantics

Answer 1

At the top, the word "MESSAGE" is written in bold in the middle of the format. Below that in left hand side, Date, Time and Salutation (Name of the person with Dear or Respected to whom the message is written) is mentioned. After that, Body of the message is written in short using simple sentences.

Loosely speaking, the system provides messages as the meanings of utter- ances. For this reason the system may be said to be a message semantics. ... "propositional semantics," in which propositions are provided as meanings.)

A message consists of the following parts: A header containing identifying and routing information. Optional properties that can be used to convey additional identifying information beyond that contained in the header. A body containing the actual content of the message.
