As has been said before on these forums, if you don't know the difference then you don't need a static IP

.
Basically a static IP is only of use if you run some kind of server on your computer and want people, (possibly yourself at work), able to access your home computer from elsewhere on the net. (Not a home network, that works OK with a dynamic IP as that IP is the external address of your router. As your address is always the same that sort of thing is much easier to organise.
Otherwise a dynamic IP is fine. In fact many people prefer one - especially if they go on forums where they might get banned.
