FTP vs. HTTP: Key Differences Explained

This article explores the differences between FTP (File Transfer Protocol) and HTTP (Hypertext Transfer Protocol). We’ll delve into their functionalities, port numbers, and other distinguishing features. We will also touch upon FTP vs SMTP.

Both FTP and HTTP are application-level protocols that rely on the transport layer for reliable data transfer. Let’s examine each protocol in detail:

FTP Protocol

FTP stands for File Transfer Protocol. Its primary purpose is to facilitate the transfer of files between computers on a network. This includes uploading files to a server and downloading files from a server. You can even attach files to email messages using FTP. FTP is particularly useful for transferring large files.

The protocol is defined in RFC959.

FTP establishes two connections between the client and the server:

• Control Connection: This connection handles commands and responses, managing the overall session.
• Data Connection: This connection is dedicated to the actual file transfer.

Authentication is required at the beginning of an FTP session. The client must provide a valid username and password to gain access. Once authenticated, files can be transferred between the two systems.

FTP supports both binary and text file formats.

The URL syntax for FTP is defined in RFC1738. FTP links typically begin with ftp://.

FTP Example:

ftp://ftp.microsoft.com/Products/

HTTP Protocol

HTTP stands for Hypertext Transfer Protocol. It’s the foundation of data communication on the World Wide Web. It’s used to retrieve web documents from a server.

To access a website, you use a URL (Uniform Resource Locator). A typical URL looks like this:

HTTP Example:

https://www.rfwireless-world.com/Tutorials/gsm-tutorial.html

Let’s break down the URL:

• https:// specifies the communication protocol (HTTP in this case, with TLS encryption).
• www designates the World Wide Web.
• rfwireless-world.com is the domain name or website address.
• /Tutorials indicates a directory within the website’s file structure.
• gsm-tutorial.html is the specific.jpgage located within the “Tutorials” directory.

Most websites are structured with multiple directories to organize their.jpgages.
