G22.2262 Data Communications Lecture Notes Fall 1983 with revisions from G22.2262 Data Communications Lecture Notes Fall 1990

These are lecture notes from a one semester course on Data Communications taught at NYU in the 1980's. These notes were written by Dr. Herbert J. Bernstein and the late Professor Max Goldstein and, along with the companion lecture notes on Network Design provide components essential to a more modern book that is under development. Even though, indeed especially because an extensive rewrite and extension is needed for the new work, making these lecture notes accessible is needed to connect the modern work to its past. We will study the tools and techniques needed to deal with communications between computers and the real world and to deal with communications among pieces of computer hardware. We will consider communications systems and media, bandwidth limitations, channel sharing and grouping, data formatting, error detection and correction, protocols, networks, I/O driver design, operating system interfaces and human interfaces.
