Understanding Data Communications
Production year 1999. Length approximately 104 minutes. VHS-NTSC format. 74-page 8.5" x 11" softcover bound workbook.

Here, we put in place a solid understanding of datacom and protocol stack fundamentals. We'll start at the beginning, reviewing the components of a data circuit: DTEs, DCEs and physical connections, then exploring practical examples of circuits and networks, allowing you to categorize and compare the different types of equipment and circuit configurations. We'll show how data is formatted for transmission, including the older concepts of "asynchronous" and "synchronous," and todays crucial concepts of frames and packets, and IP packets. Well complete the video by understanding protocol stacks: we'll review the ISO Open Systems Interconnect (OSI) 7-layer reference model, give examples of protocols used for each layer, and how a protocol stack works.

To understand networks, you have to understand what a circuit is, what a frame is, and what a packet is, and how these three elements work together. This video course explains these concepts in plain English, preparing you for the Networking videos.
