World of Computer Networking Your CCNA start - User Datagram Protocol (UDP)

The video tutorial covers the establishment and finalization of TCP connections using the 3-way handshake process. It then introduces the UDP protocol, highlighting its simplicity, connectionless nature, and lack of flow control or error detection. An example of UDP communication is provided using DNS, explaining how UDP segments are sent without connection initialization. The structure of the UDP header is detailed, emphasizing its simplicity with only four fields. Finally, the video discusses the characteristics of UDP, noting its speed and use for fast data transmission between hosts.

How does UDP handle the initialization of connections?
