Mesh Data vs Object Data?

[McLarry]

Is the objects mesh data modified in the Edit Mode and the object data modified in the Object Mode? And what is the difference between the two?

Objects, like a cube, are some sort of container for other properties. An object contains mesh data (vertices), Modifiers, etc. In edit mode, you can access and modify these mesh data and other properties, like face material. Also, an object can contain multiple meshes. Like an object with the name thingy, can contain the mesh from a cube, and from a sphere,

You can attach a material to an object. What it does is assign all the faces from the contained mesh to this single material. But in edit mode when you have access to the mesh, you can select specifc faces and assign more material to them.
