At the heart of vaping is....well, vaporization, just as the name suggests. Vaporization is the process through which a liquid is changed to a gas without combustion. It is what drives vaping, and because it doesn't necessarily "burn" anything, it introduces a significantly lesser concentration of toxic particles to your lungs. Even with a myriad of products being introduced to the vaping market each year and an orgy of sizes, shapes, and even delivery devices that murk up any kind of standard, it all happens in almost exactly the same way.
