Anyone can pretty much use the ports within this group. These ports can be assigned to companies providing a specific service. They are usually occupied by the most widely utilized services, such as STMP, IMAP, MySQL, and Apache. You may associate these groups with how ' well-known' the service running on a specific port is. Each group contains ports, based on the services they tend to. Hopefully, this brief explanation of TCP and UDP enlightens you about which protocol is better and can help you make a choice between them.

The first package sent may be received last, and the last one may be obtained first, which will cause a severe discrepancy between the collected data and the one you expect.

The UPD streamed packages are bound to arrive, however they do not do so individually. No bit of separation is present resulting in smoothening the viewing and listening experience. The downside is the fact that there is no telling if the data will ever reach its destination, in what order will it reach it, and in what condition.Īnother critical difference between the two revolves around data streaming. The information is sent regardless of the status of the remote server. UDP is a protocol that does not require an established connection. Interruption can occur ONLY if the connection between them is lost or one of the servers managing the link goes down. How it works is that two points connect, and the data starts streaming through uninterrupted.

TPC is by far more reliable as it provides a connection-based proliferation of data. Information is transmitted via ports using either the TCP or UDP protocols. Each checkpoint has a unique purpose - one of them serves cars, the other one may accommodate motorcycles, and the third Trucks or Vehicles that are transporting a specific load. When you use a service from your personal computer to send an email, for example, the program you are using knows which port to use to deliver your message.Ī vivid association of ports would be the customs. Each instance of service runs on a specific port, serving as a communication point between clients and the server. What are ports?Īny machine connected to the internet distributes the services installed on it using numeric ports. What does the port mean, and what does it represent? In this article, we will do our best and explain this and also give you the port numbers of the most commonly used services on a cPanel server.
