What is FTP host or FTP server? What is it user for?

When it comes to transferring data and files, there are a variety of different protocols available. One such protocol is the file transfer protocol (FTP). FTPs allows users to securely upload and download files from remote servers. In this blog post, we will be discussing the various types of FTPs, their differences, and how they can be used in various use cases.

What is an FTP?

An FTP is a type of protocol that enables users to securely transfer data through the internet or LAN networks. It works by establishing a connection between two computers, allowing users to exchange information over a secure channel. This means that data transferred via FTP is encrypted, making it safe and secure for users.

An FTP server is an invaluable tool when it comes to easily and efficiently put data online, migrating applications, or sharing information. FTP is basically a communication protocol that allows users to access, manage, and transfer data between their computer and a remote directory. By housing the necessary data in a remote directory server that can be accessed from anywhere on the world wide web, you can quickly make updates to your website or application without having to manually upload every file each time. Rather than being tethered to one computer running at one location, using an FTP server makes life much easier for developers as it permits them to make amendments from wherever they may be in the world.

How Does an FTP Server Work?

An FTP server works by hosting files on its server and providing access to these files via the Internet or LAN network. When someone wants to access a file hosted on the server, they need to connect to it using an FTP client. Once connected, they can then view and download any available files from the server

Various Use Cases for FTPs

An FTP server can be used in several different ways. Here are just some of them: 

  1. Transferring Data: An FTP server makes it easy to securely transfer large amounts of data quickly between two computers or servers without having to manually copy each file individually.  
  2. Setting Up An Intranet With High Availability: An FTP server can be used as part of an intranet system with high availability, ensuring that critical information remains available even if one computer or server goes down.  
  3. Hosting Data On A Shared Server: If you need to host data on a shared server, such as web content or media files, an FTP server can make it easier by allowing multiple users access from different locations without having to manually upload each file each time they need it.  
  4. Backing Up Important Files: If you need to back up important files or documents on multiple devices, an FTP server makes it easy by allowing you to keep backups in sync across all devices automatically. 
  5. Centralizing Information For Several Websites And Domain Names: If you manage multiple websites or domain names, an FTP server can help you centralize your information so that changes made on one website will automatically update all other websites as well – eliminating the need for manual updates every time there’s a change! 

Establishing a Connection 

The first step in establishing an FTP connection is setting up the command channel. This is usually done with two separate TCP connections, one for commands (port 21) and one for data (port 20). The client then sends commands to the server to establish the connection and begin transferring files. The commands are sent over port 21 while the actual file transfer takes place on port 20. Once the connection has been established, it’s time to start transferring files! 

Advantages Of Using An Ftp Server 

Using an FTP server comes with several advantages such as increased file security and privacy, greater control over who has access to what data and sharing options, and the ability to easily synchronize multiple locations without having to manually copy each file every time there’s a change needed between them all!   

Types of File Transfer Protocols (FTPs)

There are three main types of file transfer protocols—standard FTP (SFTP), FTPS, and SFTP—each with its own set of features and benefits depending on your needs: 

Standard FTP

Contrary to modern methods of data transmission, the traditional FTP or File Transfer Protocol was designed in an era where security wasn’t as much of a priority (it was developed back in 1971). As it stands, standard FTP is nowhere near as secure as its present-day counterparts, since data is transferred with little to no encryption. Although reliable, it should not be used for transferring confidential information due to the lack of data protection, as passwords and other sensitive information could be easily intercepted by malicious actors. Therefore, more secure alternatives such as SSH have become commonplace instead of this classic protocol.


File Transfer Protocol Secure (FTPS) is an advanced version of standard file transfer protocol (FTP). It adds an extra layer of security which ensures that all data passing between the client and server is encrypted using SSL/TLS encryption. This prevents hackers from accessing sensitive or confidential files. In comparison, Secure File Transfer Protocol (SFTP) offers the most secure option for file transfers as it combines SSH keys with an extra security mechanism called Secure Shell (SSH). This creates a highly secure system which makes it almost impossible for unauthorised individuals to gain access to files hosted on the FTP server.


SFTP stands for Secure File Transfer Protocol (SFTP). It’s similar to FTPS but uses SSH instead of SSL/TLS encryption which provides even greater security than its predecessor while also being much faster at transferring data due to its efficient design. It also supports public key authentication which allows you to create multiple user accounts with varying levels of access rights depending on your needs—this makes it perfect for businesses who require high levels of security when sharing information with external parties as well as internally within their organization itself. 

As you can see, there are several different types of file transfer protocols available depending on your specific needs—each has its own advantages over others so make sure you consider what type best suits your requirements before settling on one particular option! Whether you choose standard FTP, FTPS or SFTP will depend largely on what type of data you need transferred—so take some time research each one before deciding! With proper knowledge about each protocol’s capabilities and limitations, you’ll be sure find exactly what you’re looking for!
