FTP (File Transfer Protocol) is a protocol used to communicate and transfer files between computers connected to the internet via a TCP/IP (Transmission Control Protocol/Internet Protocol) network. Users who have been granted access to the File Transfer Protocol server (also known as FTP host/site) can receive and transfer files.
How Does FTP Work?
To obtain or transfer a file, an authorised user will use the protocol to request that changes be made to the server. In exchange, the server will grant you access. This is referred to as the active connection mode.
If the user’s machine is protected by a firewall, the distribution in active mode may encounter issues. The firewall typically does not permit any unauthorised external sessions.
If this problem occurs, the passive mode is used. The user establishes both the command and data channels in this mode. This mode then instructs the server to listen rather than attempt to establish a connection with the user.
How to Use FTP
There are three methods for establishing an FTP connection. Using a command-line FTP client, such as Command Prompt for Windows or Terminal for Mac/Linux, is a very simple method. It is still used by developers today for FTP file transfers.
A web browser can also be used to communicate with the FTP server. When users need to access large directories on the server, a web browser is more convenient. However, it is frequently less dependable and slower than using a dedicated FTP programme.
Using an FTP client is now the most common way to use FTP, especially for a web developer.
In comparison to the command line and web browser, an FTP client offers more flexibility. It is also more powerful and easier to manage than the other methods.
When using such a client, you can also access additional features. Users can, for example, transfer a large file and use the synchronising utility.
Conclusion
So, you can now send and receive files from an FTP server. To access the website that you manage as a web developer, you will need to use FTP with an FTP client. Furthermore, it is simpler to create and remove directories on the server, as well as read a large number of files.
