What is a key reason to use TCP?

Using TCP, or Transmission Control Protocol, is primarily advantageous due to its reliable delivery of packets. This reliability is achieved through several mechanisms that guarantee the ordered transmission of data. TCP establishes a connection between sender and receiver before the actual data transfer begins, known as a three-way handshake. This ensures that both ends are ready for the communication.

Furthermore, TCP includes features such as error checking, acknowledgments for received packets, and retransmission of lost packets. If a packet is not acknowledged within a specific timeframe, TCP will automatically resend it. This ensures that the data sent reaches the intended recipient accurately and in the proper sequence, making it particularly suitable for applications where data integrity is critical, such as web browsing, email, and file transfers.

The other options reflect characteristics that are not fundamentally tied to TCP's primary function or purpose. TCP's design prioritizes reliable data transmission, which is essential for many critical applications in network communication.
