It's an Android but not like others.
http://www.gsmarena.com/samsung_galaxy_ace_s5830-3724.php notes this but then it has TouchWiz and maybe other Samsung changes.
As such all I can offer is that http://support.google.com/android/bin/answer.py?hl=en&answer=2371340 covers basic Android 2.3 use. But since Samsung added Touchwiz nothing I write may work.
Sorry but that's all I can offer. It's not a PC but keep learning about Android and your device. Ask others around you to show you how to do more.
