IT Noobie/Newbie

Hi there i’m an IT student here in the philippines, honestly i did’nt like this course at first but since i don’t have any choice i’m trying my best to get in touch in this field. so now i’m having a practicum and i was put in an IT department, the supervisor was kind to me and i’m really expecting that i will learn a lot from this. but my point here is that my knowledge in this industry is so little, i know some basics but when it talk about networks i only have small knowledge. where can i learn more about networks and hardwares specially for corporates 🙂 thank you for who will help
