Full trust - your code can do anything that the account running it can do.
High trust - same as above except your code cannot call into unmanaged code. i.e. Win32 APIs, COM interop.
Medium trust - same as above except your code cannot see any part of the file system except its application directory.
Low trust - same as above except your code cannot make any out-of-process calls. i.e. calls to a database, network, etc.
Minimal trust - code is restricted from anything but the most trival processing (calculating algorithms).
