Final answer:
The assertion that TCP uses a connectionless design is false. TCP is a connection-oriented protocol that requires a handshake to establish a connection before sending data.
Step-by-step explanation:
The statement that TCP uses a connectionless design is False. TCP, which stands for Transmission Control Protocol, is one of the main protocols of the Internet protocol suite and is known for being a connection-oriented protocol. This means that before any data can be sent, a connection is established between the sender and the receiver through a process known as a TCP handshake. The handshake ensures that both parties are ready to communicate and that a channel is established for the data exchange. This is in contrast to UDP (User Datagram Protocol), which is a connectionless protocol that sends data without establishing a connection.
