TCP (Transmission Control Protocol) is a reliable protocol that establishes a connection between two devices and makes sure that data is sent and received successfully. It uses error-checking mechanisms and resend capabilities to ensure that data is not lost or corrupted during transmission. UDP (User Datagram Protocol), on the other hand, is a connectionless protocol that does not provide reliability or error checking. Therefore, TCP is the best choice for ensuring reliable data transmission. IP (Internet Protocol) is responsible for routing packets through the network, while DNS (Domain Name System) is used for resolving domain names to IP addresses.
