This is because there is no overhead for opening a connection, maintaining a connection, and terminating a connection. It is an unreliable and connection-less protocol which is used for services that require fast transmission of data. However, the reliability is less but it still offers efficient communication. Whenever the message is passed from a source to sender, it must pass from each layer of the protocol stack. Or what if you need both? Do you want to sleep without a headache? Thus there is absolutely no missing data. Losing all this overhead means the devices can communicate more quickly.
The packets are checked for errors to make sure the request is fulfilled correctly. It is a connection oriented and reliable protocol and is used for transfer of crucial data. There is no guarantee that the messages or packets sent would reach at all. It establishes a connection between source and destination computer before starting the communication. There is a lot of network protocols in use.
The connection is established by sending handshaking messages before sending actual data. At least to send just a single byte there need to be a session initialization and after data transfer close the session. Rather it sends data with no more hustle. Another reason is, the protocol resend all lost data packets, and those packets travel more path than a usual data does, and it makes the connection speed slower. This way, the complete message is delivered without errors.
The packets that were missed in between are already useless now. All these features make it the most common protocol available. See your article appearing on the GeeksforGeeks main page and help other Geeks. If you experience minor packet-loss, the video or audio may be distorted for a moment as the video continues to play without the missing data. A message will make its way across the internet from one computer to another. Further explaining this scenario in a real world example, think about a multi shopping complex environment and someone directed you to shop 30 Which is a barber saloon , Golden Plaza, No 21 Park Ave, to reach this place you need to know only No 21 park avenue but to get the service from saloon you need to know the shop number which is 30.

You should include your checksum because you cannot depend on this default checksum since it does not provide the required protection. It is also used in file transfers. It neither takes acknowledgement nor it re transmits the lost data. It is because it provides flow control and acknowledgment of data. How this reliability is achieved? Did you get all the packets? When you chat with your friend online, send an email, or send a page request through your browser, you send online data.
We are living in a world full of various types of networks. It maintains the session for each client request. It is highly reliable, as it uses the 3-way handshake, flow, error and congestion control. The views expressed on this blog are those of the authors and do not necessarily reflect the official policy or position of Private Internet Access, London Trust Media, Inc. If the acknowledgement is not received in time, then the message is resent.
Since it is an unreliable protocol, generally 1 to 5 percent of the data get lost on the path, and there are times when 0 percent data will reach the final point. This makes it a reliable protocol. This is not a superior connection speed for the multiplayer gamers, and it becomes a miserable experience for them. Second, it error-checks by having the recipient send a response back to the sender saying that it has received the message. Thus, a unifying set of rules is a must that should be followed world wide, in order to communicate the data between various types of computer systems. Other differences are mentioned below in the article.
And you cannot get back any missing packets either. Reliability is guaranteed delivery of the packet and latency is timely delivering the packet. There is absolutely no way of predicting the order in which message will be received. The flow maintenance feature also lacks. In transportation of packets there are two major constrains one is reliability and other one is latency.
