Note that the definition of a cognate can vary in subtleties, such as including excluding borrowed words, in/excluding compound words and words with changes in part of speech. Below is what I would consider as cognates in the text:
Kopieren - to copy
Programmen - programs
Musik(stücken) - music
Filmen - films
Netzwerken - networks
persönlicher - personal
Daten - data
Telefon(nummer) - telephone
(Telefon)nummer - number
Adresse - address
Borrowed words: Download, Internet, E-Mail
