How TCP and UDP Work | Network Fundamentals Part 7
TCP and UDP are the transport layer protocols that are used to get data from one application to another.
They have several common features, like port numbers (the network address of the application), headers, and multiplexing (allowing more than one application to access the network at a time).
But, they also have several differences. For example, TCP is connection oriented, while UDP is connectionless. TCP is ‘reliable’ while UDP is ‘unreliable’.
But if TCP has more features, why use UDP at all? The answer may surprise you!
