Transmission Control Protocol (TCP) is a reliable protocol than UDP True False

TCP and UDP are two transport layer protocols that are in opposition to one another.

While developing a reliable transport protocol, early versions of the protocol discussed in class used a NAK message, sent by the receiver to the sender to indicate a packet was not correctly received. This kind of message, however, is not found in further protocols, like GBN, SR or even TCP. Why not? In other words, why don't these protocols provide a way to signal to the sender that the received message was received with an error

TCP allows for uninterrupted, two-way communication. What do you mean by the terms "full-duplex," "connection-oriented," and "reliable delivery"?
