TOS means "Terms of Service." The abbreviation TOS means the rules that must be agreed to before using a service.

Of note, TOS can also be used as a disclaimer, especially regarding the use of websites. TOS is sometimes written as T&C meaning Terms and Conditions of the service.

TOS is also used by science-fiction tv enthusiasts to describe "The Original Series" of Star Trek. "Trekkies" (Star Trek fans) ascribe abbreviations to each series of the TV show (e.g., TNG, DS9, VOY, ENT).
