TCP is a ________________________ oriented protocol.

connection
connectionless
seamless
universal

The correct answer is: connection

TCP, or Transmission Control Protocol, is a connection-oriented protocol, meaning that it establishes a dedicated end-to-end connection between communicating devices before any data is transmitted. This connection setup process involves a handshake mechanism, specifically the three-way handshake, which ensures that both sender and receiver are ready for data transmission. In a connection-oriented protocol like TCP, there is a guarantee of data packet delivery, ordering of packets, and error-checking functionalities, which are essential for many applications that require reliable communication, such as web browsing or file transfers. Once the connection is established, TCP maintains the session for the duration of the communication, allowing for the orderly and reliable exchange of data. In contrast, connectionless protocols, such as UDP (User Datagram Protocol), do not establish a dedicated connection and send data packets without the need for a handshake, which can lead to issues such as lost packets or out-of-order delivery. This makes connection-oriented protocols particularly suited for scenarios where reliability is critical.
