Can you explain how data is transmitted via the UDP protocol?

The UDP (User Datagram Protocol) is a transport protocol that provides data transfer without establishing a connection. It does not guarantee delivery, order, or integrity of packets, but it is faster and has lower overhead than TCP.

Data transfer via UDP occurs as follows:

1. The application forms a datagram (packet) with data and the recipient's address.
2. UDP adds a header with source and destination ports, length, and checksum.
3. The packet is passed to the IP layer for routing.
4. On the recipient side, UDP receives the packet and passes the data to the application.

Features:

• No connection establishment, so no delays for setup.
• No delivery acknowledgments, so packets may be lost or arrive out of order.
• Used in applications where speed is crucial and some data loss is acceptable (e.g., streaming video, gaming, VoIP).
