Billboards are basically textured squares (two triangles) that point towards the camera and appear to be a 3D model. They are cheaper and easier to work with than models many early 3D games consisted mainly of billboards. Billboards are still used to fake 3D objects.

The XNA 3DAudio example has a good example of using billboards.

A mesh is a collection of vertices, faces and edges that define a 3d shape. XNA can import .X or .Fbx files. .X files are Files created for DirectX, while FBX is an platform independant 3D mesh file type
