Full Form of UDP
UDP stands for User Datagram Protocol. It is one of the core protocols of the Internet Protocol Suite. Here are some key points about UDP:
- Connectionless Protocol:
UDP does not establish a connection before sending data, which allows for faster transmission.
Data Transmission:
It sends data in packets called datagrams.
No Error Recovery:
UDP does not provide mechanisms for error recovery or guarantee delivery, making it less reliable than TCP (Transmission Control Protocol).
Use Cases:
Ideal for applications where speed is critical, and a few lost packets are acceptable. Commonly used in:
- Streaming Media (audio, video)
- Online Gaming
- VoIP (Voice over Internet Protocol)
Port Numbers:
- UDP uses port numbers to identify different services. For example:
- Port 53: DNS (Domain Name System)
- Port 67/68: DHCP (Dynamic Host Configuration Protocol)
In summary, UDP is a fast, connectionless protocol that is widely used in applications where speed is prioritized over reliability.
