apt-get, rpm y yum

[Francisco Roldan]

Thanks everybody for your answers on 
my Debian-Gentoo-Fedora email,
I think I am almost decided to upgrade to Fedora.

I have other question, 
I have worked with rpm since the
old days of Red hat 6, now i 
am a little confuse with Fedora, 
I haven't installed yet, but i 
have read that there is a command
'apt-get' ,  what is it ?
and what about yum ?

Can i keep usign rpm on Fedora Core 1 ?
