We can summarize the chapter with the following points:
- Coding and decoding of messages are very important processes of communication:
- Coding converts the information to an acceptable form for the transmission.
- Decoding converts the received message into an intelligible language.
- Packing bits into the frame so they can be transmitted represents the encapsulation.
- When the receiving computer receives the frame and unpacks it by taking out the bits, this accomplishes de-encapsulation.
- Communication between computers is very strict as far as the size of the message is concerned.
- Access method, flow control, and response timeout are essential parts of the message timing:
- In unicast message delivery, there is only one destination for the message
- In multicast message delivery, there are several reachable destinations for the message.
- In broadcast message delivery, all computers...
