Hi abdou-mellali! EOS stands for Electro-Optical System - you can learn more about it (and much, much more) at our Camera Museum! We hope that helps, and if you would please clarify the other part of your question, we, or the community will be happy to answer!

Also in Canon's number system the closer you get to 1, the more closer you get to their flagship model.

IE, 7D, 5D Mk(?) 1D (?), of course right now the 1Dx.

"D" stands for Digital, as in Digital Single Lens Reflex (DSLR)
