protocol in addition to TCP?
UDP is a protocol that provides a lightweight and fast data transmission mechanism. Unlike TCP, which is a reliable protocol that ensures all data packets are received by the receiver in order and without errors, UDP does not guarantee any of these features. Instead, UDP is used in cases where low-latency and minimal overhead are more important than data reliability. For example, in online gaming or in applications where a high volume of data is being transmitted, such as video streaming, UDP is used to ensure the minimum possible delay between data transmission and data reception. In summary, UDP is a protocol that serves a different purpose than TCP, and although it is less reliable, it is faster and more efficient in some scenarios.
