UDP is the abbreviation for User Datagram Protocol. There are a number of core protocols in the standard internet protocol suite. UDP is one of these. It is a section of the internet suite. It is used by programs to send short messages that are referred to as Datagrams from one computer to the other. The short messages do not a lot in the way of system resources. They are also secure communication strategies. Where TCP has previously been used/ UDP can be applied. However, UDP is not as reliable as TCP and does not guarantee the correct data sequencing. The shortcoming of UDP is that the datagrams may be lost or the order in which they were sent may be lost along the way and they arrive in a different order.
This does not in any way indicate that UDP is not useful. In fact, where speed is needed more than the reliability that is provided by TCP, UDP is a good choice to pick on. The speed with which data is exchanged through the use of UDP is owed to the fact that it has no ability to check whether data that has been sent has arrived at its destination. It is therefore more efficient to use especially in cases where one would rather have missing data than have data arriving late.
While TCP is used where communication is between a server and one client, UDP is operational where servers are communicating with several clients at once. Data is sent to several clients that are connected to the particular network. A UDP network requires the implementation of other mechanisms to the network to guarantee efficient running of traffic. A solution has been suggested in Datagram Congestion Control Protocol (DCCP). This is a program that will monitor and control congestion of traffic in any UDP network.
UDP was created in 1980 by a man called David P. Reed. His objective was to establish a swift and uncomplicated means of communication between computers that were networked. The communication procedure would not have to undergo the normal set of rules and would utilize fewer resources. Reed then came up with a program that compressed information into datagrams. The creation came in handy in the delivery of compressed high-profile papers. TCP and UDP are, to some extent supplementary. They are common in business circumstances. Depending on prevailing circumstance, one can be used in place of the other. Nevertheless, UDP is more popular in the broadcasting of voice in video.
