About FTP

File Transfer Protocol is an Internet protocol that runs in the application layer which is the standard for sending files (files) between your computer machines in a network Internet.
FTP is one of the earliest Internet protocols developed, and is still used today to perform the download (download) and upload (upload) files between the computer and the FTP client FTP server. An FTP Client is an application that can issue FTP commands to an FTP server, while the server is a Windows FTP service or daemon that runs on a computer that responds to commands from an FTP client.
FTP commands can be used to change the directory, changing the mode of delivery between binary and ASCII, evocative of a computer file to the FTP server, and download files from an FTP server.
An FTP server is accessed by using a Universal Resource Identifier (URI) using ftp://namaserver format. FTP client can contact the FTP server by opening the URI.
Using the FTP protocol Transmission Control Protocol (TCP) for data communication between the client and the server, so in between these two components will be made a communication session before data transmission begins. Before making the connection, the TCP port number 21 on the server side will listen trial connection of an FTP client and then be used as a controller port (control port) to (1) create a connection between the client and server, (2) to allow the client to send a command to the FTP server and also (3) returns the server response to the command. Once the control connection has been made, then the server will start to open the TCP port number 20 to establish a new connection with the client to send the actual data that is being exchanged during a download and upload.
FTP uses only standard authentication methods, namely using the username and password are sent in the form of tar is not encrypted. Registered users can use the username and password to access, download, and upload files he wants. Generally, the registered users have full access to multiple directories, so that they can create files, create directories, and even delete files. Users who have not registered may also use anonymous login method, by using the anonymous user name and password are filled in using the e-mail address.
