Which acronym stands for a protocol that provides reliable, ordered delivery of data?

• A. UDP
• B. TCP
• C. IP
• D. ARP

Answer: (B)

Reliability and in-order delivery are features of the transport layer, and the protocol that provides this is TCP. It establishes a connection, then sends data as a stream with sequence numbers, requiring acknowledgments and retransmitting any lost segments to ensure every byte arrives and in the correct order. TCP also manages flow control to prevent overwhelming the receiver and uses congestion control to adapt to network conditions, along with a checksum to detect corruption. In contrast, UDP is a best-effort protocol with no delivery guarantees or ordering, IP handles addressing and routing without providing reliability, and ARP is used for mapping IP addresses to MAC addresses. So, the protocol that delivers reliable, ordered data is TCP.
