Which term corresponds to the Push (PSH) flag?

• A. Synchronize (SYN)
• B. Acknowledgement (ACK)
• C. Port Scanning
• D. Push (PSH)

Answer: (D)

In TCP, the Push flag is a control bit that tells the receiving stack to pass the data to the application immediately, rather than buffering it until the buffer fills. This makes data available to the application with lower latency, which is important for interactive or real-time streams. The term that corresponds to this flag is Push (PSH) itself, because it literally names the function of the bit. The other options describe different TCP concepts or activities: Synchronize starts a connection, Acknowledgement is the ACK flag used to confirm receipt of data, and Port Scanning is not a TCP flag at all.
