Any packages that don't have a newer version in the repo that you currently
have installed. What it actually installs is entirely determined by your
distribution (guessing you're running Ubuntu since it's common and uses
aptitude), so the guys in charge of Ubuntu determine what does and doesn't
get upgraded with that command. apt-get upgrade will, in fact upgrade your
kernel if there is a kernel package in your repo. Also, some distros will
even download firmware packages and install them (but usually not the
bios). Also, without running an update there's no way to know if there are
any new packages.
If you want an explicit list of what it will upgrade, type in:
apt-get --just-list upgrade
