i can pretty much figure out how a mouse works on the ouside, but how does the computer interpret what is sent to it? in other words, how does it know that im clicking on mozilla and not konqueror?

I could be wrong: every thing on the GUI is an object. When you click the keyboard or mouse, the system takes your input and remember them, and then send them to the appropriate object. There are times when you click on a window on top, the click sent to the one on the back, depending on how your window behaviour is set up.

but how does it differ from one object to another?

each object has co-ordinants. think x,y grid, x goes up, y goes right, the bottom-left corner of your screen as (0,0) and top right as (somenumber,somenumber)the x-server knows if it receives a mouse-down(click) at co-ordinants (210,320)or whatever, that that click fell within the boundrys of whatever widgit the mouse was over.
