File Transfer Protocol (FTP)

Why File Transfer Protocol?

Although transferring files from one system to another is very simple and straightforward, but sometimes it can cause problems. For example, two systems may have different file conventions. Two systems may have different ways to represent text and data. Two systems may have different directory structures. FTP overcomes these problems by establishing two connections between hosts. One connection is used for data transfer, and another connection is used for the control connection. To check your TCP/IP you must check it by using command prompt or an easy way what is my ip.

FTP

• FTP is a standard internet protocol provided by TCP/IP used for transmitting the files from one host to another.
• It is mainly used for transferring the web page files from their creator to the computer that acts as a server for other computers on the internet.
• It is also used for downloading the files to computer from other servers.

FTP Clients

• An FTP client is a program that implements a file transfer protocol which allows you to transfer files between two hosts on the internet.
• It allows a user to connect to a remote host and upload or download the files.
• It has a set of commands that we can use to connect to a host, transfer the files between you and your host and close the connection.
• The FTP program is also available as a built-in component in a Web browser. This GUI based FTP client makes the file transfer very easy and also does not require to remember the FTP commands.

Mechanism of FTP

The above figure shows the basic model of the FTP. The FTP client has three components: the user interface, control process, and data transfer process. The server has two components: the server control process and the server data transfer process.
