Others have already given you good answers, but I wanted to summarize
a bit differently.

1.  apt-get dist-upgrade - done basically once - when you want to
change the version of the distribution you are using.  Then you don't
use it again until it is time to upgrade again.

2.  apt-get update - done every day or on a regular basis to update
the list of packages available

3.  apt-get upgrade - this actually compares the packages on your
system to the new list generated by the update and sets up a list of
packages to download and install.

So because I love to break my system and be on the bleeding edge, I
usually do the following a couple of times a day:

sudo apt-get update
sudo apt-get upgrade
