Data is sent in tiny packets, but sometimes packets get lost. How does TCP make sure all your data arrives even if a packet gets lost?

• The computer just “guesses” what data is missing

• A “response” is sent when a packet arrives. If the response is not made, the packet is resent

• TCP will crash your computer if a packet is lost

• TCP is an address for every internet connected device
