UDP Handshake
UDP is a connectionless protocol, and it does not have a formal handshake like TCP. In UDP, communication is achieved without establishing a connection. The client simply sends UDP packets directly to the server without any preliminary setup. There is no SYN, SYN-ACK, or ACK process involved.
Because of its connectionless nature, UDP is faster and more lightweight than TCP. However, UDP does not provide the same reliability and error-checking mechanisms as TCP. It does not guarantee delivery of packets or the order in which they are received.
In summary, TCP uses a three-way handshake (SYN, SYN-ACK, and ACK) to establish a reliable and ordered connection between a client and server, while UDP is connectionless and does not require any formal handshake before sending data. The choice between TCP and UDP depends on the specific requirements of the application or service being used.
