Pakiety: dane w kawałkach

Jak dane wędrują w sieci: adresy, serwery i bezpieczne połączenia - Informatyka - klasa 8 (draw)

Zdjęcie wysłane koledze nie płynie przez sieć w całości. Komputer dzieli je na małe **pakiety** (po około 1500 bajtów). Każdy pakiet ma nagłówek z **adresem nadawcy**, **adresem odbiorcy** i **numerem kolejnym**, jak koperta. **Routery** po drodze przekazują pakiety dalej, każdy wybiera najlepszą w tej chwili drogę. Pakiety jednego zdjęcia mogą więc jechać różnymi trasami i przyjść w innej kolejności, a komputer odbiorcy układa je z powrotem według numerów. Zgubiony pakiet wysyła się jeszcze raz.
