What is a typical swiss german greeting used throughout the day

The text below was taken from a german school's computer policy. there are 10 cognates present in these two paragraphs that you should be able to identify. when you find them, write them out in german and give an english translation of what the word means. (german text below) download von internet der download, d. h. das kopieren von dateien (programmen, musikstücken und filmen) die in so genannten file-sharing-netzwerken angeboten werden, ist untersagt. bekanntgabe persönlicher daten im internet schülerinnen und schülern ist es untersagt, personenbezogene daten (z. b. telefonnummer, adresse, e-mail-adresse o. ä.) bekannt zu geben. could anyone point out the cognates in this phrase? i can probably do the rest but i need with this. danke.
