Telephone networks are long network that transmit digital signals over a communication channel between the transmitter and receiver computers.
The effectiveness of a data communication system depends on three fundamental characteristics:
• Delivery: The system must deliver data to the correct destination. Data must be received by the intended device or user and only by that device or user.
• Accuracy: The system must deliver data accurately. Data that have been altered in transmission and left uncorrected are unusable.
• Timeliness: The system must deliver data in a timely manner. Data delivered late are useless. In the case of video, audio and voice data, timely delivery means delivering data as they are produced, in the same order that they are produced, and without significant delay. This kind of delivery is called real-time transmission.

Nt1310 Unit 3 Data Center Framess
788 Words | 4 PagesThe SIFS( Shortest Inter-Frame Space),derives the time between the last transmission and high priority transmissions such as positive acknowledgments(ACKs),Clear-To-Send(CTS)frames,polling responses, continuation frames in a burst transmission. priority is given to the positive ACK frames so that a station which has just completed the reception of a frame can give immediate feedback to the sender. RTS and CTS frame coordinate correspondence between sets of stations so that different stations know not the medium to be free for the time of the exchange .This is one of the reasons for why the control frames have priority over normal data transmissions. If a station finished transmitting a frame and has enough time left to send an additional frame, it is allowed to send after a SIFS.
