Introduction

Today’s computers, tablets and smartphones can communicate with the University’s systems and virtually any device on the Internet thanks to a well-defined set of devices and protocols that have evolved over the years, coordinated by the Internet Engineering Task Force (IETF).  This discussion describes the role of each of the devices that are used in modern digital communications.

In this first portion of the discussion, we will focus on basic “wired” connections where the computer sending the communication message and the computer receiving it are both physically connected to their respective networks via an “ethernet cable”, i.e., copper or fiber optic cable that is capable of exchanging data using the “ethernet” communications protocol.
