LANs demystified

Description

LAN training course description

A concise overview course covering Local Area Networks with particular emphasis on the use of Ethernet and Wireless LANS. As well as explaining buzzwords we cover how the technology works at a simple level. After defining LANs the course moves onto Ethernet and switching also covering VLANs. WiFi is then covered, with coverage of 802.11 standards and frequencies along with integrating WiFi with Ethernet. The course then covers routers and their role in connecting networks and the course finishes with a comparison of Ethernet vs WiFi and when to use them.
