UDP is a connectionless protocol and uses a best effort basis for transmitting data.

Explanation

User Datagram Protocol (UDP) operates in a connectionless manner, meaning it does not establish a dedicated end-to-end connection before data transmission begins. Instead, UDP sends data packets (datagrams) directly to the recipient without requiring any feedback or acknowledgment that the packets were received. This approach is referred to as “best effort” because UDP does not guarantee reliable delivery, ordering, or error checking, which are features of connection-oriented protocols like TCP (Transmission Control Protocol). As a result, while UDP can be faster and more efficient for certain applications, it might lead to packets being lost or delivered out of order. This makes it well-suited for time-sensitive transmissions, such as video streaming or online gaming, where speed is more critical than reliability.
