UDP (User Datagram Protocol) is an essential part of the Internet Protocol suite. It is a connectionless protocol that provides fast, reliable, and efficient delivery of data across networks. UDP is used for broadcast and multicast services, video streaming, online gaming, and other real-time applications. Its main advantage is its low overhead, allowing it to send more data with less bandwidth. UDP also offers the ability to broadcast data to multiple recipients, making it ideal for streaming applications. Developers favor UDP because it offers them the flexibility they need to create applications that meet the needs of their users. With UDP, developers can create applications that are low latency, reliable, and efficient.
