HTTP– stands for hypertext transfer protocol and is a networking protocol for distributed, collaborative, hypermedia information systems resulting in http being the foundation of data communication for the World Wide Web. HTTP enables users to write Web browsers, Web servers, automatic page downloader’s, link-checkers, and other useful tools. HTTP means that web users can request information from a web server and the web server can provide responses to those requests. Every time we access a web site HTTP is used.

WAP – this is mainly used to access the mobile web from a mobile phone or PDA. It stands for wireless application protocol and is an open international standard for application-layer network communications in a wireless-communication environment. WAP supports activities such as music downloads and mobile phone emailing. WAPs that use displays and access the Internet run what are called micro browsers; these are browsers with small file sizes that can accommodate the low memory constraints of handheld devices and the low-bandwidth constraints of a wireless-handheld network. This is why basic mobile phone’s that access the internet using WAP produce simplified versions of the website.

GSM – is an abbreviation for Global System for Mobile communication. It digitizes and compresses data, then sends it down a channel with two other streams of user data, each in its own time slot. GSM is a digital mobile telephony system that is highly popular in Europe as well as other parts of the world. GSM enables users to make use of their phones for mobile communications and means that users can use their phones in places other than their country of origin. This technology provides users with high quality signal and speech channels resulting in network operators being able to provide their customers with cheap calling and text messaging options.

3G - is a generation of standards for mobile phones and mobile telecommunications services fulfilling specifications by the International Telecommunication Union. 3G is the better know abbreviation of International Mobile Telecommunications-2000 and can also be referred to as 3^rd Generation. The services of this application include wide-area wireless voice telephone, mobile Internet access, video calls and mobile TV, all in a mobile environment. Meaning that all of this can be accessed using a mobile phone. Products such as the iPhone have embraced this 3^rd generation technology, making the most of its benefits.

MMS - Multimedia Messaging Service, or MMS, is a standard way to send messages that include multimedia content to and from mobile phones. An MMS is often referred to as a picture message because it allows the sender to send a photograph using their camera-equipped handset to another mobile phone that is equipped to receive MMS messages. MMS can also be used to deliver videos, pictures, text pages and ringtones.

GPRS – stands for General Packet Radio Service is a packet oriented mobile data service on the 2G and 3G communication systems global system for mobile communications. GPRS provides moderate-speed data transfer, by using unused time division multiple access (TDMA) channels in, for example, the GSM system. Objectives such as providing flexible services at relatively low costs can be met using GPRS.

Bluetooth - is an open wireless technology standard for exchanging data over short distances using short wavelength radio transmissions. This can be done from fixed devices such as Bluetooth enabled computers and laptops as well as mobile devices such as mobile phones. Photographs, videos and audio files can all be sent via Bluetooth.

ADSL – stands for Asymmetric Digital Subscriber Line and is a form of Digital Subscriber Line technology. This data communications technology enables faster data transmission over copper telephone lines. ADSL is much faster than a conventional voiceband modem and enables wireless Internet access that can be used by laptops, computers, iPhones, the iPod touch and even the Playstation 3.

Broadband – is a high data rate Internet access and is typically contrasted with dial-up access using a 56k modem. Because dial-up modems are limited to a bitrate of less than 56 kilobits per second and require the dedicated use of a telephone line broadband has become a much more desirable alternative for accessing the internet. Broadband is much faster and does not disturb the telephone line when in use.  Rather than paying as you use most broadband packages are a fixed monthly rate, making it a much cheaper way to access the Internet.

VoIP - is a general term used for a family of methodologies, communication protocols, and transmission technologies that deliver voice communications and multimedia sessions over the Internet. Applications such as Skype use this technology to enable users to make voice calls over the Internet.
