Internet - Protocols

The Internet has to work with different types of network. It needs to overcome the problems caused by this: different types of computer hardware using different operating systems and running different software applications. The Internet uses communication protocols in order to overcome these problems.

A protocol is an agreement or a standard set of rules between two or more parties. Internet protocols ensure the transfer of data between hardware devices. These protocols deal with transmission speeds, port numbers, data format, start and end signals, etc.

The Internet uses the following protocols.

• Transmission protocols:
   – TCP/IP
   – IP address.

• Internet service protocols:
   – HTTP
   – FTP
   – POP/SMTP.

The Internet is required to transmit data to thousands of millions of different hardware devices. The transmission of data is achieved by using transmission protocols.
The Internet also offers a number of different services and each service has its own internationally recognised protocol. This means that the World Wide Web and e-mail use different service protocols. The United Nations Communications Committee – UNCC – specify many of these protocols.

If users set their computer to these international protocols they can receive Internet services. For example, the World Wide Web protocol uses HTTP – HyperText Transfer Protocol which uses Port 80 to receive information at transmission speeds of 33 kilobits per second (kbps) or 56kbps. If a user does not set up his/her computer system to these settings then he/she will not be able to receive the World Wide Web.
