"I've always been afraid of typing as far as rm -rf / and brushing Enter." *
"Oh, I did that once."
"Where was that?"
"Well... we used to have a mail server."
* Therefore instantly removing everything on the computer, although most systems protect against this

Essentially, Ubuntu doesn't let you run with admin status as standard, like Windows; it asks you for the admin password every time you try and do something that would modify the system, and gives you temporary admin priveleges for that command only. (There's a timer on the password so you don't have to enter it literally every time if you're doing a lot at once, but you still need to repeat sudo for each command.) It stops a whole lot of viruses and nasty stuff, simply because the standard users can't do stuff to bugger the system up, and the virus most often doesn't know what to do if it gets asked for a password as it's used to just walking in and doing its thing.
It's amazing what effect a simple game of Simon Says does for security. :P But yeah, it's about the first thing you learn, roughly equivalent to C:\DOS\run for Linux. :P
