     Internet Protocol and Standards - HTTP,             SHTTP, FTP, SMTP,    TCP/IP, URL, URI            

 SHTTP (Secure Hyper Text Transfer Protocol)                                 

 The secure Hyper Text Transfer Protocol (SHTTP) is a set of security mechanism defined for protecting the internet traffic. This includes the data entry forms and internet-based transactions. 

 The services offered by SHTTP are quite similar to those of SSL. However, SSL has become highly successfull SHTTP works at the application layer, and is therefore, tightly coupled with HTTP, unlinke SSL. 

 SHTTP supports both authentication and encryption of HTTP traffic between the client and the server. 

  FTP (File Transfer Protocol)                                                             

 • It is used to exchange files on the internet. 

 • To enable the data transfer FTP uses TCP/IP. 

 • FTP is most commonly used to upload and download by form the internet. 

 • FTP can be involed from the command prompt or same graphical user interface. 

 • FTP also allows to update (delete, rename, move and copy files to a server) 

 • It uses a reserved port on 21. 

 •Two Types Connection 

                 a. Control Connection  

                 b. Data Connection 

 DNS - Domain Name Systems                                                            

Example – W. W. W education.com                                      

                                 Might Tranate to          DNS                           

                  198.105.232.4 

  SMTP (Simple Mail Transfer Protocal)                                            

 • It is an internet standard for e-mail transmission. 

 • SMTP connections are secured with SSL/ Secure Socket Layer. 

 • In SMTP, the message are stored and then forwarded to the destination. 

 • SMTP uses a port number 25 of ICP. 

 • SMTP is a push protocol.

  URL (Uniform Resource Locators)                                                   

 The address on the internet is known as  URL. Everything on the internet that is of value, like a web page, a file, a news group and so on is called a resource. Every resource has an address and this address is called URL, which stands for uniform resource locators. 

 A uniform resource locator (abbreviated URL; also known as a web address, particularly when used with HTTP) is a specific character string that constitutes a reference to a resource. Most web browsers display the URL of a web page in an address bar. 

 A typical URL might look like. 

 http: // www.mck.edu.au/subjects/IPT 

 http -  Hypertext protocal (The set of rules for the transfer of data on the world wide web)

www -  World Wide Web (indicates the resource is a webpage)

mck -  Domain Name (The specific name of the website)

edu -  Toplevel Domain/Domain extension (indicates the type of site, educational, commercial, gov etc.)

au -  Geographical Domain (indicates the source of the website which in this case, is australia)

subjects -  

IPT - Directory/File path (The address location or resource with in the site folder)

  URI (Uniform Resource Identifer)                                                    

 It is a string of characters used to identify a resource on the internet either by location or by name, or both. 

 For example 

 Name : Flink Side Smack. 

 Address : 7083 Columbia street                   

                woon socket, RI 02895

 Two types 

 i. Fragment URN(URN - Universal Resource Name) - It refers the location of content using anchor indentifer. 

 ii. Relative (URL- Uniform Resource Locator)-It may contain URN on Fragment URI that define the document in side the content.
