What Is The Complete Range Of TCP And UDP Well-Known Ports?

This TCP is a connection-oriented protocol. But what is connection-oriented protocol i.e it means that if two devices are connected would like to communicate with each other via a TCP, they must send some formal messages to each other in order to set up the connection before any data can be transferred. This TCP will also be called a reliable protocol. When we send the data to another device via a TCP, the other device will acknowledge the received data. In this way, we can assure you that we have received the right information. This transmission control protocol will be keeping track of the data that is being sent, and in what order it is being received. This is the common thing in many of the networks. We will be sending the information out in a particular type of order, it is because of the way the traffic flows. And when it is received on the other side these frames may come out of the order. All the TCP’s can handle that piece. If anything will be missing during the transmission, it will again retransmit the data and put everything into the original form.

Now, the user datagram protocol will be a different type of protocol comparing with the TCP protocol. It is a connection-less protocol. In the user datagram protocol, there will be no standard startup process in order to set up communication on another device. Here there will be no formal tear-down process. It simply sends the information into another device without any type of warning to it. Unlike the transmission control protocol, this will be an unreliable protocol. Here it represents that there will be no acknowledgment of the data is sent. So that there will be no retransmission of the data. Usually, the applications which are using UDP will not at all be concerned about the data that is transmitted or not.

In the TCP/IP, we will start using the port numbers especially when we are referring to the special numbers. In the single IP packet, we will be having the IP address, server port number, client port number. This is how the end stations will send the information to each other and find their way to the correct service. we have nonephemeral ports which are permanent. These are set up for the particular application. And we have the ephemeral ports, these ephemeral ports will be having temporary port numbers. these port numbers are used to connect and start a conversation and once this conversion is over, this port number will be no longer in use. Let say if a device is communicating to a web server by using the ephemeral port on your device, so we can create a connection to a non-ephemeral port on that web server. Here when we give a port number to a device, it may be a TCP or UDP. This number is going to range between 0 and 65535. Here most of the servers will use the nonephemeral port numbers, although there are some of the services which are completely dynamic.
