Critical to this process is the fact that each connection must have a destination before it can be sent. Only then can TCP handshake occur. Here, the Internet Protocol (IP) acts as the other side of the TCPIP coin.
The header of each data packet includes the IP address of the intended recipient, which ensures that the data gets to where it is needed. Once the IP address is identified, the TCP process can initiate the iran telegram data data transfer. However, the received data must go to the correct port, so TCP packets include port information. Think of an IP address as a zip code, and TCP port information as a specific house number. Finally, TCP packets include a sequence number, similar to the numbered pages in a letter; these determine the order in which the packets are sent.
While TCPIP has become the standard for secure and reliable data transmission over the Internet, the primary benefit of the IP approach is its flexibility, and TCP is not the only way to get data from point A to point B.
What is UDP
User Datagram Protocol (UDP) is a lightweight data transfer protocol that builds on top of IP. However, instead of the lengthy handshake process of TCP, UDP sends small independent packets known as datagrams without first cross-referencing the connection. While this may seem risky, UDP is designed to discard information and avoid catastrophic communication failures.
