A wide-area network (WAN) is a data communications network that connects user networks over a large geographical area. WANs have several important characteristics that distinguish them from LANs. The first lesson in this module will provide an overview of WAN technologies and protocols. It will also explain how WANs and LANs are different, and ways in which they are similar.
Students who complete this module should be able to perform the following tasks:
- Identify organizations responsible for WAN standards
- Explain the difference between a WAN and LAN and the type of standards and protocols each uses
- Describe the role of a router in a WAN
- Identify internal components of the router and describe their functions
