A novice

I am studying in Hunan University of Arts and Sciences majoring in Information Management and Information System. I am a sophomore student. The foreign teacher wants to teach us professional knowledge with better software, and I also look forward to learning different things.
Our class was a introduction to Networks. The lecturer was Patrick Wong, who explained the concepts step by step from easy to difficult, and taught us hand by hand in the experiment class. He asked us to combine theory with practice.
