There are types of protocols used to transfer data between devices In computer networks. One of the important protocols is UDP. In this article, we will discuss UDP Full Form and how this protocol plays a role in network communications. Let’s explore more about the definition, characteristics, and uses of UDP in the context of computer networks.
What is UDP and the User Datagram Protocol?
UDP (User Datagram Protocol) is a communication protocol that operates on the IP protocol (Internet Protocol). In computer networks, This protocol is designed to provide fast and efficient communication between devices, especially applications that require fast data transfer and do not pay much attention to the reliability of delivery.
This protocol works by sending datagrams. Datagrams are data packets containing information sender to the recipient. Datagrams come in independent packets and are not dependent on previous or subsequent packets. This protocol is considered unreliable or “best effort” because it does not provide an automatic error detection or recovery mechanism.
UDP does not guarantee reliable delivery, data sent via UDP can be lost, arrive out of order, or even not reach its destination at all. Therefore, if you need data integrity and reliability in your application, choose another protocol such as TCP. It should be considered.
Comparison between TCP and UDP in Computer Networks
Comparison between TCP and UDP protocols in computer networks is shown in the table below:
Protocol TCP UDP Reliability Ensures reliable data delivery Does not guarantee reliable data delivery Data delivery Sequential delivery based Non-sequential delivery Delivery confirmation Requires delivery confirmation Does not require delivery confirmation Error recovery Has error recovery mechanisms Does not have error recovery mechanisms Delivery speed Slower due to larger overhead Faster due to smaller overhead Overhead Higher due to the use of complex features Lower as it does not have complex features Suitable applications Applications that require reliability and sequential data delivery (e.g., file transfer, email) Applications that require real-time data transfer (e.g., video streaming, online gaming) Example usage HTTP, FTP, SMTP, SSH DNS, VoIP, video streaming, online gaming
If you need reliability and integrity, TCP is a better choice. However, if speed and efficiency are the main factors, UDP may be a more suitable choice.
