Commit means that you are putting your local files into CVS.

Update is the other way around: getting the latest version (or another specific version) from CVS to your local machine.

For more information, see the CVS manual.

And if it's any consolation, it took me long enough to learn that myself. I always thought of "updating" something as pushing out my changes to long-term storage, but in version control, that's a commit and "update" is when other people's changes get pulled into your copy.

Or in short, it's you being updated, not the project repository.

With other words, an "update" gives you what has been "committed" by everyone else since your last "update".

The soul is dyed the color of its thoughts. Think only on those things that are in line with your principles and can bear the light of day. The content of your character is your choice. Day by day, what you do is who you become. Your integrity is your destiny - it is the light that guides your way. - Heraclitus

I think Jesper's is pretty clear, but here's a little scenario.

I start a new project and need to create a new workspace so I check out the code from CVS. Then someone tells me about the project and I go home. The next morning, I update my workspace to get all the changes that have occurred the previous day. After all, I want to start with the latest code. I code/test the method assigned to me until lunch. I update my workspace again to make sure everything works with my change. Then I commit my change so others on the team can see it.
