Web Protocols

Protocols

W3C

The World Wide Web (WWW) began as a project at the European Organisation for nuclear research (CERN).  This is where Tim Berners-Lee created the World Wide Web.  Tim Berners-Lee left the CERN and joined the Massachusetts Institute of Technology Laboratory for Computer Science (MIT/LCS).  This is where Tim Berners-Lee with the support from the European Commission and the Defence Advanced Research Projects created the World Wide Web Consortium (W3C).

W3C tries to enforce compatibility and agreement among industry members in the adoption of new standards defined by W3C.

This means that when people are creating web sites they will have to follow a number of protocols for their website to work and for other people to see it.

Wireless Application Protocol (WAP)

WAP is the technical standard for accessing the internet on a mobile device. A WAP browser is a web browser for mobile phones that use this protocol. When WAP did not exists mobile service providers had limited opportunities to offer interactive data service. WAP supports internet and web applications such as;

·         Email by mobile phone

·         Sports results

·         New headlines

·         Music downloads

 

Global System for Mobile Phones (GSM)

The GSM was developed to replace the first generation analogue cellular networks, this is known as digital. This was expanded over time to include data communication from circuit switched transport to packet data transport via GPRS (General Packet Radio Service) and EDGE (Enhanced Data rates for GSM Evolution). Further improvements were made for the third generation followed by the fourth generation.

3^rd Generation Protocols (3G)

This is a set of standards used for mobile devices, telecommunication services and networks that comply with the Internet Mobile Telecommunication (IMT-2000) specifications by the International Telecommunication Union. 3G finds applications in wireless voice telephony, mobile internet access, fixed wireless internet access, video calls and mobile TV.

MMS

MMM stands for Multimedia messaging service. This is a standard way to send messages that include multimedia content to and from mobile phones. It extends the core SMS (Short Message Service) capability that allowed exchange of text messages only up to 160 characters in length.  MMS was created so that it would enable service providers to “collect a fee every time someone snaps a photo.”

General Packet Radio Service (GPRM)

GPRM is a standard for wireless communications which runs at speeds up to 115 kilobits per second, compared with current GSM (Global System for Mobile Communications) systems' 9.6 kilobits.

GPRS, which supports a wide range of bandwidths, is an efficient use of limited bandwidth and is particularly suited for sending and receiving small bursts of data, such as e-mail and Web browsing, as well as large volumes of data.

 

Bluetooth

Bluetooth is an open wireless technology standard to exchange data over a short range from fixed and mobile devices. Bluetooth is a wireless technology developed by Ericsson that is designed to be a cable replacement. It operates on the 2.4GHz frequency band, like WiFi, and is officially known as IEEE standard 802.15.1. It is most commonly used with wireless headsets and car kits, but can also be used for network access, moving files from one device to another, or with wireless input devices such as a mouse and keyboard - among many other uses.

Broadband

This refers to high-speed data transmission in which a single cable can carry a large amount of data at once. Before broadband dial-up was how people downloaded songs, movies used emails etc. Dial-up was very slow as it would take up to 28 hours to download a 700MB movie. The most common types of Internet broadband connections are cable modems (which use the same connection as cable TV) and DSL modems (which use your existing phone line). Because of its multiple channel capacity, broadband has started to replace baseband, the single-channel technology originally used in most computer networks.

 

Voiceover Internet Protocol (VOIP)

Voice over IP (VoIP, or voice over Internet Protocol) commonly refers to the communication protocols, technologies, methodologies, and transmission techniques involved in the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet.
