The very first thing to know about being a sysadmin is knowing what particular system you will be administering. Or, at least, that’s what I imagine.
In this case, it is Linux. Basically, the goal here is to learn system administration, specifically on Linux-based systems. I’m not so sure if there is such a thing as a Windows or a Mac sysadmin but I imagine there should be.
On that note, I would once again like to state that “Linux is EVERYWHERE.” Contrary to popular belief (at least where I live), Linux doesn’t only exist in homes of people who are way deep into computers. It exists even in the palms of the most common users.
Lots of people will claim that they don’t use Linux while using an Android phone, tablet, etc. It’s plenty shocking when you make them realize that they have been using Linux all the while.
So, yes, Linux is EVERYWHERE. It exists in desktops, laptops, netbooks, tablets, cellphones, TV’s, cars… You get the idea.

Another interesting fact about Linux being everywhere:
Linux is based off the UNIX operating system, and Mac OS X is a registered UNIX OS. In the operating system battles it has come down to UNIX vs Windows.
