What is the difference between TCP and UDP?

They both build on top of the Internet protocol. These packets are treated similarly, as they are forwarded from your computer to intermediary routers and on to the destination. However, they are the most widely used. It is the most commonly used protocol on the Internet. The web server responds by sending a stream of TCP packets, which your web browser stitches together to form the web page and display it to you.

Transmission Control Protocol TCP is a connection-oriented protocol that computers use to communicate over the internet. TCP provides error-checking and guarantees delivery of data and that packets will be delivered in the order they were sent. User Datagram Protocol UDP is a connectionless protocol that works just like TCP but assumes that error-checking and recovery services are not required. Instead, UDP continuously sends datagrams to the recipient whether they receive them or not. They are the most commonly used protocols for sending packets over the internet. TCP establishes a connection between a sender and receiver before data can be sent. UDP does not establish a connection before sending data.


2- In which layer TCP and UDP protocols are operating? 3-What is the difference between TCP and UDP header? 4-What are the main features.


difference between udp, tcp and sctp pdf

It helps you to create a virtual network when multiple computer networks are connected. It is specifically designed as a model to offer highly reliable and end-to-end byte stream over an unreliable internetwork. In this tutorial, you will learn: What is TCP? What is UDP? How TCP work?

TCP vs. Logical connection setup, data forwarding, routing and delivery error reporting are the network, Join ResearchGate to discover and stay up-to-date with the latest research from leading experts in, Access scientific knowledge from anywhere. The User Datagram Protocol UDP is used by apps to deliver a faster stream of information by doing away with error-checking.

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.

UDP is Connectionless protocol and no connection need to be established. But in real life, can anyone provide examples the more the better of applications uses of TCP and UDP to demonstrate the difference?

TCP vs UDP

Applications where reliable transmission of data matters. Performing flow control between end users. Different protocols have been developed to meet them. Application of UDP. Function: As a message makes its way across the internet from one computer to another. TCP header size is 20 bytes since, and TCP header contains options, padding, checksum, flags, data offset, acknowledgement number, sequence number, source and destination ports, etc. All the back-and-forth communication and deliverability guarantees slow things down.

Suppose there are two houses, H1 and H2 and a letter have to be sent from H1 to H2. But there is a river in between those two houses. Now how can we send the letter?


First we have to understand what Modbus is. Short and simple differences between Tcp and Udp protocol: 1) Tcp - Transmission control protocol and Udp - User.

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.

Хорошо бы помедленнее. Беккеру не хотелось так быстро уходить от алтаря, но когда две тысячи людей ждут причастия, а обслуживают их всего восемь священнослужителей, было бы неприличным медлить с этим священным глотком. Чаша была уже совсем близко, когда Халохот заметил человека в пиджаке и брюках разного цвета. - Estas ya muerto, - тихо прошептал он, двигаясь по центральному проходу. Ты уже мертвец. Времени на какие-либо уловки уже не .

Ведь он был пацифистом и не стремился к разрушению. Он лишь хотел, чтобы восторжествовала правда. Это касалось ТРАНСТЕКСТА. Это касалось и права людей хранить личные секреты, а ведь АНБ следит за всеми и каждым. Уничтожение банка данных АНБ - акт агрессии, на которую, была уверена Сьюзан, Танкадо никогда бы не пошел.

А у входа толпились бандиты.

 Да, мистер Клушар, конечно, понимаю. Это цена, которую приходится платить за известность. - Действительно.  - Клушар вздохнул с видом мученика, вынужденного терпеть всякий сброд.

Глядя на оживающий монитор, он подумал, известно ли Стратмору, что в лаборатории систем безопасности нет ни души. Подходя к шифровалке, он успел заметить, что шторы кабинета шефа задернуты. Это означало, что тот находится на рабочем месте.

Я звонила вам на мобильник. И на пейджер. - На пейджер, - повторил Джабба.  - Я думал, что… - Ладно, не в этом. В главном банке данных происходит нечто странное.
