Vnc Server

What's it used for?
Can I use it on my ipod touch?

Thanks and inb4 "google it" as I'm too lazy.

1. Basically lets you control the computer the server is ran on from another computer.
2. Yes you can, I have before.

How are you too lazy to type 3 letters in Google, but not to type a like 50 character thread?

You can also use Teamviewer for remote controlling a computer via iPhone / Android
