Assembly addressing

Hi! I want to understand how assebly addressing works, but I cannot understand it. So... Whats the difference between effective addressing, linear and ddirect addresing and how to calculate them? Thanks a lot...

You the, uh, & sign in front of your registers to indicate... direct addressing

Unless you use really old CPUs and/or OSes, dont bother.

I want to calculate them and understand. I dont want to write them in code.

Depends on the processor architecture... HIBT
