FTP is similar to HTTP, which is the protocol used in browsing the Word Wide Web. There are a number of Shareware programs on the Internet available to the public that will allow a person to access FTP servers. Sometimes referred to as an FTP client, the FTP program is useful for transferring binary files and uploading text and graphics to your Web Site. While it is possible with most browsers to FTP to a site, some versions only allow you to download files from a site.
Most browsers only allow entry to anonymous ftp sites.
The browser will display the documents at the site in a form that looks something like a directory listing for your computer. You can upload files to the site in many browser versions by dragging and dropping files from the desktop to the browser. Most FTP software will require the user input a few basic values to be able to access a site. Sometimes this will be in the form of numbers such as 162.39.76.4. This set of numbers is called an IP Address.
