HTTP or The Hypertext Transfer Protocol as its otherwise known is an application protocol for distributed, collaborative hypermedia information systems. Http is the foundation of data communication for the World Wide Web. Http is the protocol to exchange or transfer hypertext. The development of HTTP was coordinated by the Internet Engineering Task Force and the World Wide Web Consortium, culminating in the publication of a series of Requests for Comments most commonly RFC 2616 since June 1999 which defines HTTP/1.1, the version of HTTP in common use. HTTP is designed to perimit intermediate network elements to improve or enable communications between clients and servers. HTTP is designed to permit intermediate network elements to improve or enable communications between clients and servers. High-traffic websites often benefit from web cache servers that deliver content on behalf of upstream servers to improve response time. Web browsers cache previously accessed web resources and reuse them when possible to reduce network traffic. HTTP proxy servers at private network boundaries can facilitate communication for clients without a globally routable address, by relaying messages with external servers. The term HyperText was founded by Ted Nelson who in turn was inspired by Vannevar Bush's microfilm-based 'memex'. Tim Berners-lee first thought of the 'WorldWideWeb' project (now known as the World Wide Web). Berners-Lee and his team are credited with inventing the original HTTP along with HTML and the associated technology for a web server and a text-based web browser.
Wap
Wap otherwise known as Wireless Application Protocol is a technical standard for accessing information over a mobile wireless network. A Wap browser is a web browser for mobile devices such as mobile phones that uses the protocol. Before the introduction of Wap, mobile service providers had limited opportunities to offer interactive data services but needed interactivity to support Internet and web applications such as: email by mobile phone, news headlines, tracking of stock-market prices, sports headlines and music downloads.
GSM
GSM otherwise known as global system for Mobile Communications originally Groupe Special Mobile is a standard set developed by the European Telecommunications Standards Institute (ETSI) to describe protocols for second generation (2G) digital cellular networks used by mobile phones. It became the de facto global standard for mobile communications with over 80% market share. The GSM standard was developed as a replacement for first generation (1G) networks and originally described a digital, circuit-switched network optimized for full voice telephony. Over time this was expanded over time to include data communications, first by circuit switched transport then packet data transport via GPRS (General Packet Radio Services) and EDGE (Enhanced Data rates for GSM Evolution or EGPRS. Improvements were further made when the 3GPP developed third generation (3G) UMTS standards followed by fourth generation (4G)LTE Advanced standards.
3G
3G short for third Generation, is the third generation of mobile telecommunications technology. 3G telecommunication networks support services that provide an information transfer rate of at least 200 kbit/s however many services advertised as 3G provide higher speed than the minimum technical requirements for a 3G service. Further on 3G releases 3.5G and 3.75G which also provides mobile broadband access to smartphones and mobile modems in laptop computers. 3G finds application in wireless voice telephony, mobile Internet access, fixed wireless Internet access, video calls and mobile calls. This is a set of standards used for mobile devices and mobile telecommunication use services and networks that comply with the International Mobile Telecommunications-2000 (IMT-2000) specifications by the Internet.
