I used the stickied topic in this forum, as well as
this resource in order to find what I needed for a home lab. I am looking to use it in order to study for the CCENT, and eventually use it to study for the CCNA. However, I am having a hard time finding an OS version 12.4. About every single one I have manage to stumble across is 12.1. Is this a big difference? Am I just not looking hard enough?
I am almost completely new to networking (I know what it is, took a basic college class, and have done minor work on it) so I want to make sure I don't buy completely useless hardware.
