My Networking Basics course starts this Thursday at Macquarie Community College at Carlingford and runs over the next three weeks. This course will give you a understanding of things such as TCP, IP addressing, switches, wireless, routers, firewalls and more. It is aimed at those who little of no networking experience and want to better understand the technology of getting machines to talk to each other.
You can find more information, including enrolment details here:
The course will also give you hands on experience with the technology in a computer lab and comes with a comprehensive set of course notes.
