If you are new and trying to come up to speed and have absolutely no idea of where to start,
then begin your career by going to a library where you can borrow the network related books for free. Start with the basic TCP books as suggested, but then progress to the books called: A+ , Network+ , then CCNA, then CCNP.
At some point you will need to start classes. There is a Network+ class, then take the CCNA class., etc… What you are pursuing is very challenging and interesting. Best of Luck.
I’m from Western Australia and Im an IT Co-Ordinator for a large mining group in Africa. I interview for guys often and they say the same when they are new to the industry. I think its important to have a basic understanding of network fundimentals especially TCP/IP.
In Western Australia you have several REALLY great Uni’s starting with <a href=”http://www.curtin.edu.au/”>Curtin Uni</a>
also look at <a href=”http://www.murdoch.edu.au/”>Murdoch</a>Introduction to Networking
Look at understanding the folowing:
Fundamental Network Characteristics
Types and Sizes of Networks
Network Performance Issues and Concepts
Network Standards and Standards Organizations
Backgrounder: Data Representation and the Mathematics of Computing
