I am currently new to the world of administration and have somewhat of a decent knowledge on networking. However I want to improve and advance my knowledge within the field. I have been informed the taking certified classes is a waste of time and money. Instead I have been told to read up and study on your own and practice with test computers about building a functional network.
Does anyone have any suggestions on books to read, websites to visit, or programs to use that will help expand my knowledge base within the subject of computer networking?
