Message size

During the communication of two persons, there is no written standard on how big the size of the transmitted message should be. In fact, there is a mutual understanding that the messages that they transmit are usually broken into smaller sentences. This is due to the fact that the person who receives the message is able to process (understand) it. Almost the same happens when two computers communicate. Transmitted messages are broken into small parts, as shown in Figure 2.3, so that the receiving computer has time to receive, process, and display the message as comprehensible content.

Unlike communication between people, communication between computers is very strict as far as the size of the message is concerned. This implies that, depending on the communication channel, the size of the messages is different, which means that frames that exceed the standard of the message size by being too long for the defined channel or too short in size are not delivered:
