First, we’ll find out what the term “FTP” means.

FTP (File Transfer Protocol) is a protocol from the TCP/IP that is required to exchange information over the Internet from one computer to another. The application protocol we are considering has existed for about forty-two years. Since that time, FTP has changed significantly, increasing its benefits. In each country, FTP is the most used and popular protocol when working with files on the Internet.

What is “File Transfer Protocol” for?

With the FTP protocol, you can do the following:
– Exchange different files with users;
– Upload, files to any server or site (home pages to free servers that provide them with a place);
– Download a variety of files from FTP-servers;

Therefore, if you want to have access to movies, music, any programs, text documents that are available only via FTP, you just need to know about the existence and purpose of this protocol.

How and where is the “File Transfer Protocol” used?
The FTP protocol is used:
– To solve issues of access to a variety of files;
– When using the reserves of other computers (direct or indirect);
– To ensure the protection of the user;
– For the reliability and efficiency of information exchange.

TCP is the channel through which information is exchanged in FTP. This exchange functions on the basis of technology “client-server”. Personal data can not be transmitted using this protocol, in view of the fact that all information is transferred between the server and the client – it is open. Also, if you encounter an FTP protocol, be aware that each FTP server requires authentication from you.

Authentication is the procedure for checking the validity. In our case, this is the authentication of the user by comparing the password he entered with the password in the user database.

That is, to authenticate the user must enter his name (identifier) ​​and password. This will give him the opportunity to have access to certain information. If you are not registered as a user, you can use anonymous (guest) login. To do this, you need to enter the word “anonymous” as the identifier, and the password will be your e-mail address.
