Let's consider these modes in more detail. In the active mode, the server itself establishes a data transfer connection to the client, in passive, vice versa. Depending on the method of establishing a connection for data transfer, active and passive FTP operation modes are distinguished. The fact is that there are two options for the development of a client-server interaction scenario. What is an active and passive mode? How are they associated with ports That is, to open the server, the client must go to the FTP server port, and through it go to the host. And in order to connect to this channel, you need a specific port. And this protocol works through the TCP channel. There is no better way to exchange voluminous data than through the FTP protocol.

Such a protocol is convenient for those people who do not care about the web-interface of the store, but who appreciate the download speed and the number of files that can be stored on the server.

FTP is the data transfer protocol, necessary for the customer and server to quickly exchange various files. After all, there are more than six thousand ports, which is enough for any computer.

Therefore, for each application, a unique port must be allocated - that is, a number that is not yet occupied by other programs.Дevelopers of operating systems have long been using this method of distributing programs according to numbered protocols, and it has proven itself well. If all programs run on the same вЂњtrackвЂќ, then a traffic jam will quickly form on it. A port is just a digit of the transport protocol. This is done so that applications do not conflict with each other during an attempt to connect to the network. They are needed so that programs can connect to them through the network. The computer operating system has a certain limited number of ports. If you sort everything out, then everything is extremely simple.

You will learn which is a standard port for FTP, how to change the default settings for the ports and unlock it in the firewall and router. This is what will be discussed in the article. But for this, you need to sort it well out, and in particular, you need to understand what is FTP port, what is it for and how to configure FTP port number. Through such servers, you can download music, movies, pictures, and other files, as well as handle a site with a host working through a data transfer protocol. If you try to figure it out from the very beginning, then working with the FTP server over some time will become one pleasure for you.
