UDP (User Datagram Protocol)

UDP (User Datagram Protocol) is a method used for sending data over the internet that emphasizes speed and efficiency. Unlike other protocols, it doesn't check if the data arrives correctly or in order, making it faster but less reliable. It's useful for applications where quick delivery matters more than perfect accuracy, such as streaming videos, live broadcasts, or online gaming. Essentially, UDP sends small packets of information swiftly without waiting for acknowledgments, allowing real-time communication, but it’s up to the application to handle any missing or out-of-order data.
