The aim of this short introductory tutorial is to explain the basic differences between the two and why each protocol is needed, and when they are used. TCP is a connection orientated protocol with built in error recovery and re transmission. With a telephone connection you first need to setup the connection by dialing the number, and once the calling party answers you have a both way communications channel. With TCP you set up the connection using the 3 way handshake as shown below:. The TCP transport takes care of errors on the link, and the application can be confident that the data received is error free. TCP is used by application protocols that need guaranteed message delivery.
The Internet Protocol IP is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking , and essentially establishes the Internet. IP has the task of delivering packets from the source host to the destination host solely based on the IP addresses in the packet headers. For this purpose, IP defines packet structures that encapsulate the data to be delivered. It also defines addressing methods that are used to label the datagram with source and destination information. Historically, IP was the connectionless datagram service in the original Transmission Control Program introduced by Vint Cerf and Bob Kahn in , which was complemented by a connection-oriented service that became the basis for the Transmission Control Protocol TCP. Its successor is Internet Protocol Version 6 IPv6 , which has been in increasing deployment on the public Internet since c.
One of the differences is that TCP is a connection-oriented protocol as it establishes an end to end connection between computers before transferring the data. On the other hand, UDP is a connection-less protocol since it does not determine the connection before sending data. When we ponder over the layer 3 protocols which work on IP, these are connectionless, unacknowledged and unreliable. Therefore, it would not be possible to provide the guaranteed delivery of the data. This emerged the need for the TCP and UDP protocol, which facilitate the automatic management and deals with the problems like congestion control and flow control. However, designers also thought to build these abilities directly into the IP as it was before when there was just a single protocol TCP, but all these features were provided at the cost of time and bandwidth. The better solution was to define the two protocols at the transport layer and let the network layer IP to take care of elementary data movement on the internetwork.
TCP vs UDP: What's the Difference?
There are two types of Internet Protocol IP traffic. TCP is connection oriented — once a connection is established, data can be sent bidirectional. UDP is a simpler, connectionless Internet protocol. Multiple messages are sent as packets in chunks using UDP. TCP ensures a reliable and ordered delivery of a stream of bytes from user to server or vice versa.

TCP vs UDP -What’s The Difference?
With that said, UDP is known for being faster and more up-to-date, yet many systems still rely on TCP to download batches of information. Users will need to take a look at their specific IP needs to make an informed decision about which protocol is best for them. Transmission Control Protocol TCP is connection-oriented, meaning once a connection has been established, data can be transmitted in two directions. TCP has built-in systems to check for errors and to guarantee data will be delivered in the order it was sent, making it the perfect protocol for transferring information like still images, data files, and web pages.

Хейла нигде не было. Тогда он вернулся в кабинет и прикрыл за собой дверь, затем заблокировал ее стулом, подошел к столу и достал что-то из выдвижного ящика. В тусклом свете мониторов Сьюзан увидела, что это, и побледнела. Он достал пистолет. Он выдвинул два стула на середину комнаты.
Очень хитро придумано. Ключ к Цифровой крепости зашифрован и недоступен. - Ну разумеется! - Она только сейчас поняла смысл сказанного.
