I recently asked a question on StackOverflow on How decompiling works. I have noticed multiple other questions (this, this, this, this, this, and many others) at different times, similar to this one -- they are asking how a particular process or concept works. It seems to me that these are some of the best questions on StackOverflow because they are not localized at all, and any visiting user can understand what is being said without having to take away its user-specific context.
I only have about 391 rep, so I'm a little while away from the 1500 rep required to create a tag. So I am proposing that there be a howitworks tag created for questions like this (by someone other than me).
