A hands on training course introducing the concepts of data communications, moving on to covering both LAN and WAN technology. Quizzes are used extensively to ensure material has sunk in and to maximise learning time. Hands on sessions ensure that by the end of the course delegates have made cables, built LANS and WANS, configured TCP/IP, switches and routers.
Anyone who requires a technical introduction to networks.

"The course provides an exceptional insight on the vast areas of data communications and networking."
"Very well thought out and structured course. Would recommend 100%. Lots of equipment, good quality. Gave insights in things you wouldn’t normally think about."
This structured course uses Instructor Led Training to provide the best possible learning experience. Small class sizes ensure students benefit from our engaging and interactive style of teaching with delegates encouraged to ask questions throughout the course. Quizzes follow each major section allowing checking of learning. Hands on sessions are used throughout to allow delegates to consolidate their new skills.
