Computer Networks · Lecture 2 Introduction to Data Communication · 1 Data Communications · 2 Fundamental Characteristics The effectiveness of a data communication system depend on four 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 the data accurately. Timelines In the case of video and audio, timely delivery means delivering...
