Udp Protocol -

: Because it doesn't track connections or manage data flow, the protocol has very little processing overhead.

: An optional field in IPv4 (mandatory in IPv6) used to detect data corruption. UDP vs. TCP: Key Differences udp protocol

The connectionless nature of UDP makes it a common tool for DDoS attacks . In a , attackers send a massive volume of datagrams to random ports on a target server. The server, trying to process these requests, quickly exhausts its resources, leading to a service outage for legitimate users. : Because it doesn't track connections or manage

: Fast-paced games rely on UDP to provide real-time updates without the lag caused by TCP's error-checking. TCP: Key Differences The connectionless nature of UDP

: Data transmission starts without prior communication with the receiver.

UDP is a transport layer protocol. Unlike TCP, which requires a "handshake" to establish a connection before data can be sent, UDP allows a sender to begin transmitting data immediately. This "fire-and-forget" approach makes it significantly faster but means the protocol itself does not guarantee that packets (called datagrams ) will arrive in the correct order, or at all.
