TCP vs UDP "Cheat-Sheet"
At some point, whether for an exam or an interview, all network engineers will need to explain the difference between TCP and UDP at the transport layer.
More than the buzz words and flash-card terms about these two protocols, it is important to understand the purpose behind the protocols and why an application would be built over one or the other.
In this video we will take a look at these two core protocols and examine how they are different, what they look like in Wireshark, and what their header values mean. Hopefully this information will help on a future test, job interview, or a day-to-day analysis problem.
