Networking Overview - Half Day
This course establishes a ‘baseline’ of knowledge and the students get a opportunity to review network concepts from a troubleshooting perspective. Network basics are reinforced with hands-on examples.
The first lesson taught to the students is to boldly ask the question, “So What?”. This will ensure the instructor and students fully understand the theory or concept just presented. If you can’t answer that question, then you've missed something.
The goal of the course is to empower the students with enough knowledge to immediately reference. The habit of questioning leaves them with an inclination to understand new technology and become an efficient troubleshooter.
