They're more or less the same thing really.

SEO is Search Engine Optimization.

SEM is Search Engine Marketing.

Both are terms used to describe the process of building your website around the idea of getting as high as you possibly can in the search results in popular search engines.

This can be quite tricky at times but you should start by making an investigation into 'tags', not to be confused with HTML tags, which are keywords picked up by search engines.

Make sure your website has these keywords so that if someone searches for something that can be found on your website a link will appear in the search results to your site

SEO involves trying to make a page appear higher in search results (there are two ways to do this, try to cheat (get short term benefits, then long term penalties) and by just making the page better).

SEM involves paying search engines for advertising slots beside results.

Search Engine Optimization (SEO) is the term used for making sure that your web pages contain the correct content in the correct areas (i.e. Title Tags, Image Alt Tags, Image Title Tags as well as Meta data) in the right way so that the search bot (computer) reading your pages knows it is about those key words that are going to be used by people searching for what you have to offer.

SEM - Search Engine Marketing involves a great deal more than your own website. In my humble opinion, investing in Search Engine Marketing efforts prior to optimizing your website is not smart. If you really want long term results from your search engine marketing efforts you need to make sure your website delivers what you are telling the search engines it delivers.

Search Engine Marketing is the coordination of multiple web based and other resources to drive traffic to your website. It is the process of making sure there are links to your site from other appropriate websites (not link farms). There are many free ways to optimize your search engine marketing if you are willing to take the time and learn the tools such as a Facebook Fan Page, LinkedIn Page, Twitter Page, Blog and many more.

They're very different things.

In practical terms:

SEO (search engine optimization) means tweaking your site (and other factors) so that you show up as high as possible in UNPAID search engine results.

SEM (search engine marketing) means paying for advertising that appears alongside the normal (unpaid) results in search engines.
