UDP is fast, TCP is more reliable, but definitely slower. So applications that require speed and can stand some packet loss will use UDP. Those that dont need blazing speed, and cant tolerate loss as much, will use …
Jul 03, 2017 · UDP is used when speed is desirable and error correction isn’t necessary. For example, UDP is frequently used for live broadcasts and online games. For example, let’s say you’re watching a live video stream, which are often broadcast using UDP instead of TCP. The server just sends a constant stream of UDP packets to computers watching. As stated above, the main reasons why some application implementers (like the original NFS design team) used UDP was because of it's speed and low overhead. As TCP implementations improved over the years, most applications have switched to using TCP but some still offer a UDP variant. If it uses the UDP protocol to send and receive data, it will use a UDP port. Figure 1, below, is a represenation of an IP address split into its many TCP and UDP ports. Note that once an Common UDP Applications and Server Port Use Table 148 shows some of the more interesting protocols that use UDP and the well-known and registered port numbers used for each one's server processes. It also provides a very brief description of why these protocols use UDP instead of TCP. UDP characteristics include the following: It is a connectionless protocol. It is used for VoIP, video streaming, gaming and live broadcasts. It is faster and needs fewer resources. The packets don't necessarily arrive in order. It allows missing packets -- the sender is unable to know whether a In computer networking, the User Datagram Protocol (UDP) is one of the core members of the Internet protocol suite. The protocol was designed by David P. Reed in 1980 and formally defined in RFC 768. With UDP, computer applications can send messages, in this case referred to as datagrams, to other hosts on an Internet Protocol (IP) network.
Jan 05, 2019 · Enter UDP. UDP. UDP stands for User Datagram Protocol. Recall that a datagram and a packet are more or less the same thing. UDP, also built on top of the IP protocol, works similarly to TCP, but is simpler and faster. The main difference is that UDP doesn’t require the recipient to acknowledge that each packet has been received. Any packets

What is UDP (User Datagram Protocol)? Both UDP and TCP run on top of IP and are sometimes referred to as UDP/IP or TCP/IP; however, there are important differences between the two.For example, UDP enables process-to-process communication, while TCP supports host-to-host communication. Furthermore, TCP sends individual packets and is considered a reliable transport medium. On the other hand, UDP sends messages, … TCP vs. UDP: Understanding the Difference
