TCP (Transmission Control Protocol) is the protocol that establishes a connection, ensures reliable and ordered delivery of data, and resends any lost packets. UDP (User Datagram Protocol) does not provide these features and is used for applications that prioritize speed over reliability. IP (Internet Protocol) is responsible for routing packets between devices, but does not guarantee the delivery of packets or provide error checking. DNS (Domain Name System) is used for translating domain names into IP addresses.
