Looking for a recommendation about Linux

The company I work for was getting rid of an old computer (64mb RAM). It works fine so I took it home with the idea of installing Linux on it. I figure Linux will work with the small amount of RAM simply because it does not have all the overhead of Windows.

Now I have absolutely zero experience with Linux, but I would like to learn the OS. My question is can Ireceive some recommendations on what version to install. Thanks.
