PDA Synching HOW? curious?

Question

I'm very confused about "Synching" up devices. I get the concept that after the synch (say for a palm pilot) ..both the computer and the palm pilot's information matches BUT, here is what baffles me.... If I want to add info to my computer notes etc etc... (like add addresses or phone numbers etc... (in hopes the Palm pilot will get them after a synch up) ...here is what messes with my head..
If I also delete and add things to my PDA while i'm out shopping or whatever (say erase eggs i bought) .., which info overrides which?? I have altered info on BOTH devices so how could a sych POSSIBLY work? It would undoubtedly erase some data right? If i erase address on the PDA but ADD some on the computer palm software/// a sych would be dissasterous, so what am I supposed to do ? never add info on the computer side at all? i DON'T GET THIS ..thank you

Ok, what you have is somewhere in the menu is this. You will have the option of 1. PDA overides computer 2. Computer overrides PDA. On my phone it states, if there is a conflict the Computer overides, or if there is a conflict the phone overides. Both on the same principle.

You can use ActiveSync to keep information up-to-date on both your device and your PC. If you make a change in one place, the next time you synchronize, the change is automatically made to the corresponding information on the other computer. No matter where you are viewing the information, you know it's up-to-date
