No, UDP (User Datagram Protocol) does not have a concept of windowing like TCP (Transmission Control Protocol) does. TCP and UDP are two different transport layer protocols that operate on top of the Internet Protocol (IP) to facilitate communication between applications.
TCP uses a sliding window mechanism for flow control, which involves the sender and receiver negotiating a window size that determines how much data can be in transit before receiving an acknowledgment. This mechanism helps regulate the flow of data and ensures efficient and reliable communication.
On the other hand, UDP is a connectionless protocol that does not have the same flow control and reliability features as TCP. UDP is a simpler protocol that provides a minimal set of features, including basic checksum for error detection and port numbers for identifying different services.
Since UDP is connectionless and lacks the sliding window mechanism, it does not have the concept of windowing as seen in TCP. UDP is often chosen when low overhead and simplicity are prioritized over features like reliable, ordered delivery, and flow control. While UDP is faster and more lightweight, it does not provide the same level of error recovery and sequencing as TCP. Therefore, the choice between UDP and TCP depends on the specific requirements of the application or protocol being used.
