Network Classmate Latest Questions
1. UDP is connectionless, which means that it does not require an initial three–way handshake between the sender and receiver, unlike TCP. This makes it faster than TCP and more suitable for real–time applications like DNS.
2. UDP is lightweight and efficient for small messages, making it the preferred transport protocol for DNS.
3. UDP does not require any acknowledgments from the receiver, so there are fewer overhead packets that need to be sent to guarantee delivery of the data. This improves the efficiency of the entire communication process.
4. UDP also supports broadcasting, which is useful for DNS queries that require a response from multiple sources.
1. Faster: UDP is faster than TCP because it does not have the same overhead associated with connection establishment and tearing down.
2. Low latency: UDP can provide low latency for applications that require quick response times.
3. Reliability: UDP is connectionless and does not guarantee reliability, but DNS can implement its own mechanism for ensuring reliability.
4. Multicast support: UDP supports multicast, allowing a single host to transmit data to multiple hosts at once. This is useful for applications like DNS, which needs to broadcast DNS queries to multiple hosts.
5. Stateless: UDP is stateless, meaning no connection needs to be established and maintained between hosts. This makes it easier to scale.
