Identify one key difference between TCP and UDP.

• A. TCP is faster than UDP
• B. TCP is connection-oriented while UDP is connectionless
• C. TCP does not guarantee data delivery while UDP does
• D. TCP is used for video streaming while UDP is not

Answer: (B)

One key difference between TCP and UDP is that TCP is connection-oriented while UDP is connectionless. This distinction highlights the fundamental operational characteristics of both protocols. TCP establishes a connection before any data can be sent. It involves a process known as the TCP handshake, where a connection is set up between the sender and the receiver. This ensures that both parties are ready to communicate, and establishes parameters for the data transmission. Because of this connection-oriented nature, TCP can provide reliable data transfer, error correction, and flow control, ensuring that data packets arrive in order and are re-sent if lost in transit. In contrast, UDP does not establish a connection prior to sending data. It simply sends packets called datagrams to the destination without any handshake or connection setup. This leads to faster transmission speeds since there is no overhead for establishing and maintaining a reliable connection. However, with UDP, there is no guarantee that the data will arrive at all, and packets may arrive out of order or not at all. This makes UDP suitable for applications where speed is more critical than reliability, such as live video or audio streaming. The relationship between connection-oriented and connectionless protocols is fundamental in understanding how different types of network communication can be effectively utilized based on the specific requirements of
