# 8.3 Utilizing UDP

The User Datagram Protocol (UDP) operates as a protocol in the Transport Layer, forming a crucial part of the Internet Protocol suite (UDP/IP suite). Unlike TCP, UDP lacks reliability and operates in a connectionless manner, eliminating the need for prior connection establishment before initiating data transmission. 

Similar to the process of establishing a connection with TCP, connecting via UDP involves entering the IP Address and Port Number, as shown in the following screen.

Clicking the Connect button prompts the display of a connection progress screen, resembling the presentation observed during the drone connection using TCP.

Upon successful connection, a notification will confirm " **Communication Link Established**," and the top bar of the screen will change to a vibrant green color.
