What type of traffic is described as using either TCP or UDP depending on the need for error recovery?

  • video
  • voice
  • data
Explanation & Hint:

The type of traffic described as using either TCP (Transmission Control Protocol) or UDP (User Datagram Protocol) depending on the need for error recovery is:

data

To elaborate:

  1. Video: Video streaming typically uses UDP for most real-time streaming applications because it allows for faster transmission of data. The loss of some packets (which might happen with UDP) is generally tolerable in video streaming, as it might only result in minor quality degradation, which is often preferable to the delay that would be caused by using TCP for error recovery.
  2. Voice: Similar to video, voice communication often uses UDP. In voice-over-IP (VoIP) and other real-time voice services, maintaining the timely delivery of packets is usually more critical than ensuring every single packet is received. The minor packet loss characteristic of UDP does not significantly impact the overall quality of voice communication and is preferable to the latency that TCP’s error recovery mechanisms would introduce.
  3. Data: General data transmission can use either TCP or UDP, depending on the need for reliability and error recovery. TCP is used when it’s essential to ensure that every packet of data is received accurately (e.g., file downloads, web page loads, and sending emails). In contrast, UDP might be used for scenarios where speed is more critical than reliability, such as live data feeds or certain types of gaming traffic. The choice between TCP and UDP in data transmission hinges on the specific requirements for error recovery and speed.
