Lab 3.3.12.2 WAN acronyms - overview

Estimated time: 60 min.

Objectives:

  • Review some of the more common WAN related acronyms and terminology
  • Check your knowledge of WAN acronym definitions

Background:

The computer and networking field uses an incredible number of acronyms and abbreviations, sometimes called TLAs (or Three Letter Acronyms). Many of these are Wide Area Networking (WAN - another TLA!) related. It is important when discussing WANs with a coworker or industry representative that you understand the meaning of these acronyms or at least can define the words that make them up. This exercise will highlight some of the more common acronyms and terminology used.

Tools / Preparation:

Before beginning this lab you should read the Networking Academy Second Year Companion Guide, Chapters 8 and 9 on WANs and WAN Design. You should also review Semester 4 On-line chapters on WANs and WAN Design. Compete in teams or work alone. The following is a list of resources:

  • Semester 4 Online glossary and the Companion Guide text glossary

Step 1 - Define the following WAN acronyms and terms

Try to define as many of these WAN related acronyms as possible as a pre-test and then take this challenge again at the end of the semester to see how many more you know. Give yourself a point for the definition of the acronym and a point for related terms or a more detailed definition.
