I have an electrum wallet that have a 9 word seed, but on the internet is a lot off 12 word seed. So is a 9 word seed good?

I have downloaded two wallets First called: electrum-xvg-win-amd64 25.612 kb
                                             Second called: electrum-xvg-win64 47.368 kb
What is the difference between those 2?
