Should I choose TCP or UDP? [Solved] (2022)

Should I use TCP or UDP?

Typically, applications that transfer data files will use TCP since the protocol's latency and performance issues are not that critical. UDP benefits applications that need to receive data quickly even if accuracy suffers. This is why real-time applications like audio and video streaming will often use UDP.... read more ›

Why TCP IP is more reliable?

Unlike UDP, TCP provides reliable message delivery. TCP ensures that data is not damaged, lost, duplicated, or delivered out of order to a receiving process. This assurance of transport reliability keeps applications programmers from having to build communications safeguards into their software.... see more ›

Where do we use TCP and UDP in real life?
