This sort of thing is very dependent on a person's age too.
I know a lot of my peers would know what FAQ means and what a password is. Even some of the "less" tech savvy people. But late adopters who are still using 10 year old PCs usually don't know.
Before I hear claims of ageism, it is just a fact that a higher percentage of the older generations don't know how to use computers. It isn't ALL of them but they didn't have the benefit of growing up with computers as a tool, to the point where they become second nature.
