CVs tend to be more detailed and used more in academic circles; resumes in the rest of the world. They are used for similar purposes, but you’ll find that there are slightly different format & content rules for resumes (which, by the way, have only one accented e - the second one [sorry, pet peeve], but can also be spelled sans accents).
For example, if you’ve been working for a year or two you would not start your resume with an Education section - your work experience is more to the point, and therefore is expected to go first. Or you might start with a Skills section at the very top - what you know how to do can be more important than where you’ve been doing it lately.
Generally you would not see a Professional Interests section in a resume. If you want to mention this type of thing, it goes in your cover letter. You would also not include References, though you’d prepare a separate sheet with those and have it available at the appropriate point in the process.
I could go on for a while, but my suggestion is to go to your local library or book store, and browse through some How-To books on resumes. You’ll get the idea pretty quickly.
The good news is that you’ll be able to use most of your CV material in your resume.
PS - If they’re so similar, you ask, then can’t I just send in my CV? Well, you can, of course, but it’s always better to give prospective employers - and their HR staff - what they are looking for. A CV instead of a resume could make you seem a bit pretentious (too much detail listed that’s not relevant to the workplace you are aiming for) or give the impression that you are an entrenched academia type, thus excluding you from consideration for a “real-world” job. Best to play the game by the rules.
