"Hijab" is the concept of Islamic dress and literally means "veil". The hijab is made up of the headscarf, "khimar", and the "jilbab", a long dress down to the ankles that covers a woman's whole body. Often "hijab" is just used by people (i.e. the media and individuals) to mean the whole Islamic dress code, whether one just covers one's head (as some do) or if they wear the whole outfit and cover their inner garments with a an outer one (the jilbab) as other do.
Hope that helps,
it seems you are from West Arabic countries, as Jilbab in East Arabic countries is with the head cover part
