HelpSomeone can explain me how remote exec work?

i've been pretty new to dayz hacking,and i see many people out there claiming that remote exec bypasses are the only ones which work(i also see many people like me,not knowning how to use them).Using yolohack-survival hack and executing scripts(i am talking for non be servers) wasn't so difficult.But getting a remote exec bypass to work is challenging.So has anyone here enough patience to bare with me and explain me how is this supposed to work,or even give me a good source since googling hasn't helped me a lot.thanx in advance everyone

I have no experience with .dll editing
But the remote executors most people talk about are used in most file based menus (.sqf) for example rustler, XtwisteD, monkey menu, ...
Some scrips need a remote executor to work, such as server side scripts (Nuking, infecting players, ...)

These menus I'm talking about do require a working bypass to launch and protect you from kick/bans.
