Morphology

DOS = D + O + S

This is an acronym/initialism (Denial of Service); the letters themselves are not meaningful morphemes and do not transparently reveal the sense.

Etymology

DOS can also mean Denial of Service, which is about 'denying' a 'service' to real users by flooding a server so it cannot work, like a crowd blocking a shop door so no customers can get in.
