(Info from Internet Chatroom)
What is the difference between turning a Layer ON/OFF vs FREEZE/THAW?
If a layer is turned off the objects on that layer can still be selected through the "all" option of most commands. If it is frozen this wont happen. AutoCAD basically "ignores" all objects on frozen layers.
