These are the protocols that cannot be part of the TCP/IP protocol suite. Most commonly known internet protocols are:
HTTP stands for hyper-text transfer protocol. HTTP is not really a part of the TCP/IP suite but it uses TCP/IP for transporting web pages over the Internet. We see http: all the time, usually as the beginning of a website address. Since all web pages use http: many people will leave it off when displaying their address, such as http://www.businessineconomy.com. Most new word processors and email clients even recognize website addresses such as the fictitious one in the previous sentence and will automatically create a hyperlink (hypertext link) to the web page. A hyperlink is the underlined words you click on to go to a website. What a wonderful invention this is!
FTP stands for File Transfer Protocol. Although HTTP will also do an excellent job of transferring files, FTP is designed specifically for that purpose. FTP is faster and more efficient than HTTP at moving large files from one computer to another. Although our web browser, such as Internet Explorer or Netscape, can be used as an FTP client more typically we will use a separate software program such as WS-FTP or CuteFTP to transfer files by FTP. Most website development applications have an FTP client built in since this is by far the most common method of transferring a website developed on one computer to the server that will host it.
