FTP, an acronym for File Transfer Protocol, is a network protocol that allows the efficient transfer of data between a client and a server on a network. It is one of several ways available to send and receive files over the Internet and is commonly used to upload files to a web server or download files from a web server to a local computer.

Origin, History and Evolution of FTP

FTP is one of the oldest network protocols used today. Its origins date back to the 1970s, when the foundations for the creation of the Internet as we know it today were laid.


FTP originated as part of the ARPANET project, the precursor to the Internet. In 1971, the first FTP specification, known as RFC 114, was published. Back then, FTP was a very basic file transfer protocol that allowed users to connect to a remote server, list files, and download them.


Over the years, FTP has evolved to offer greater functionality and security. In 1980, a new specification, RFC 765, was published, which added the ability to upload files to the server and provided additional commands for managing files and directories. This specification also introduced the concept of "passive mode", which allows the client to initiate all data connections, which is useful when the client is behind a firewall.

The current FTP specification, RFC 959, was published in 1985. This version introduced "active mode", in which the server initiates the data connection. It also introduced the concepts of file types and transfer modes, which allow the customer to specify how data should be transferred.


Since then, several updates have been made to the FTP protocol to improve security and efficiency. For example, FTPS and SFTP are extensions of FTP that provide data encryption to enhance security. Several FTP clients and servers have also been developed that provide more user-friendly user interfaces and additional features, such as the ability to resume interrupted file transfers.

Despite its age, FTP is still a valuable tool for transferring files on the Internet. It is used by organizations around the world to manage websites, share files, and perform other tasks related to file transfer.

How FTP works

FTP works using a client-server architecture. The FTP client is the software that is installed on the local device and used to connect to the FTP server. The FTP server is the computer that stores the files and where the client connects to perform file transfer operations.

File transfer is done in two stages. First, the client connects to the server through a process called "connection control." Once the connection is established, the client can send commands to the server to perform actions such as listing available files, uploading a file, or downloading a file.

Advantages of FTP

Using FTP has several advantages that make it easier to transfer files on the web. Some of these advantages include:

  • Efficiency: FTP allows the transfer of large files efficiently, making it ideal for transferring media files, databases, and other large files.
  • Control: FTP offers greater control over the file transfer process compared to other methods. For example, you can specifically select which files to transfer and in what order.
  • Security: Although standard FTP is not secure, there are secure versions such as SFTP and FTPS that provide encryption to protect data during transfer.

Disadvantages of FTP

While FTP offers several advantages, it also has some disadvantages:

  • Complexity: FTP can be more complicated to set up and use than other file transfer methods, especially for less technical users.
  • Insecurity: As mentioned above, standard FTP is not secure. The data is transmitted in plain text, which means that if intercepted, it can be read by anyone. This includes the usernames and passwords used to log in to the FTP server.
  • Inefficient with small files: Although FTP is efficient for transferring large files, it can be less efficient for transferring many small files due to the time it takes to establish and close connections for each file.

Implementation of FTP in Digital Marketing

In the context of digital marketing, FTP is a vital tool for website management and digital file transfer. It is used to upload new content to the website, such as web pages, images and videos. In addition, FTP can be useful for backing up website files and moving large volumes of data for digital marketing analytics.

FTP can also be useful for sharing large files that can't be emailed with colleagues or clients. For example, graphic designers can use FTP to send large design files to clients for review.
