The most common example of a connection-oriented protocol is
The transport layer in the osi modelfunctions- connection
Until data transmission starts, a connection-oriented service creates a dedicated connection between the communicating entities. It’s designed to look like a telephone device. The user creates a connection, uses it, and then releases it to use a connection-oriented service. The data streams/packets are sent to the receiver in the same order as they were sent by the sender in connection-oriented services. Connection-oriented services can be provided in one of two ways. The following are examples of connection-oriented services: Connection-Oriented Services Benefits Connection-Oriented Services’ Drawbacks
35c3 – transmission control protocol
Connectionless refers to network protocols that allow a host (i.e., computer) to send a message to a recipient without first establishing a connection, also known as a session, with the recipient.
A protocol is a format for doing something that everyone agrees on, such as communicating between computers. Before any data is sent, link-oriented protocols enable the hosts to use a preliminary protocol to create an end-to-end connection. They’re often referred to as dependable network providers because they ensure the data gets to its intended destination. The Transmission Control Protocol (TCP) is a protocol that focuses on creating connections.
In connectionless protocols, on the other hand, the transmitting host simply sends the message out into the network without first checking that the receiver is available and ready to receive it, and then makes every effort to deliver it. The message’s packets may take different paths because they are independent of one another. There is no assurance that they will arrive and that they will arrive without mistakes, duplicates, delays, or out of order. Even, if they arrive, there is no acknowledgement, and if they do not, there is no retransmission.

TCP is a link-oriented protocol that establishes a path, or virtual connection, through switches, routers, proxies, and other devices before initiating any contact. To create the virtual end-to-end link, various mechanisms such as routing djikstras shortest path algorithm exist. As a result, it’s used for browsing HTML and other sites, as well as making purchases and using web applications in general.
UDP is a connectionless protocol, meaning it only has a destination and nodes simply move it on if it arrives as quickly as possible. As a result, packets arriving out of order, via various routes, and so on are normal. As a result, instant messengers and other app developers consider UDP to be an ideal solution.
In real life, if you want to send data over the internet without thinking about the time it takes to get there or the order in which it gets there, use UDP. If you want a solid route until you start throwing packets, and if you want your data packets to arrive in the same order and with the same latency, use TCP – I’ll use UDP for Torrents and TCP for PayPal!
When you need to transfer a large volume of data (> 1 kB) and need it all to arrive at the same time, TCP is the way to go. TCP is used to transport almost all data across the internet – HTTP, SMTP, BitTorrent, SSH, and so on.

Audio samples are embedded in data packets for transmission over an IP network in VoIP. A single packet of audio usually comprises 10 to 30 milliseconds of audio. TCP and UDP are two of the most frequently used Internet connection protocols for data transmission.
Packets of data travel around the Internet. Consider them as letters: The packets come in an envelope with a to/from address, much like letters. TCP and UDP are two different kinds of envelopes. They both transport data and use IP addresses, but the outside envelope is special. Consider the differences between USPS and FedEx. The IP address of the packet’s origin (source address) and destination (destination address) is printed on the envelope (destination address). Since TCP is so widely used on the Internet, it is often combined with IP and written as TCP/IP.
TCP acts as the “FedEx” portion of the previous analogy. When two servers “talk” TCP, a formal connection is created. When one side sends a packet, the other side responds with a packet confirming the packet’s arrival. The packet is re-sent if no acknowledgment packet arrives after a certain period of time or if the acknowledgment notes that there was an issue. It can take a few seconds for a packet to be completely transmitted successfully. TCP is the protocol for WWW sites and email, among other things, and is designed for accuracy rather than timeliness.
