Hi RyRi420, have you asked the person who gave it to you if they know what is on it? Also did it not come with firefox? Are you able to check if it has an application called iceweasel?
also please try the following commands in the terminal if you could.
[~]$ ls /etc/redhat-release
[~]$ ls /etc/debian_version
ls: /etc/debian_version: No such file or directory
Installing Ubuntu might be the best option for yourself however as Mr. Alex suggested, however I don't think eee PCs generally come with CD-ROM drives what might cause issues with trying to install it.

BUT there is humbleness in not being condescending, after all there is no standard command that actually can tell you what linux distribution you are using... which has always been a problem after all. There are a couple of scripts around that attempt this but generally these only tell you the branch that the OS you are using comes from...
