Wi-Fi (also spelled Wifi or WiFi ) is a popular technology that allows an electronic device to exchange data wirelessly (using radio waves ) over a computer network , including high-speed Internet connections. The Wi-Fi Alliance defines Wi-Fi as any " wireless local area network (WLAN) products that are based on the Institute of Electrical and Electronics Engineers ' (IEEE) 802.11 standards ". [ 1 ] However, since most modern WLANs are based on these standards, the term "Wi-Fi" is used in general English as a synonym for "WLAN". Only Wi-Fi products that complete Wi-Fi Alliance interoperability certification testing successfully may use the "Wi-Fi CERTIFIED" trademark.

A mobile ad-hoc network ( MANET ) is a self-configuring infrastructureless network of mobile devices connected by wireless . Ad hoc is Latin and means "for this purpose". [ 1 ] Each device in a MANET is free to move independently in any direction, and will therefore change its links to other devices frequently. Each must forward traffic unrelated to its own use, and therefore be a router . The primary challenge in building a MANET is equipping each device to continuously maintain the information required to properly route traffic.
Overview of a Java virtual machine (JVM) architecture. Source code is compiled to Java bytecode, which is verified, interpreted or JIT-compiled for the native architecture. The Java APIs and JVM together make up the Java Runtime Environment (JRE). A Java virtual machine ( JVM ) is a virtual machine that can execute Java bytecode . It is the code execution component of the Java platform . Sun Microsystems has stated that there are over 5.5 billion JVM-enabled devices. [ 1 ]
WebKit is a layout engine software designed to allow web browsers to render web pages . It powers the Apple Safari and Google Chrome browsers. Opera has announced that their browser will also move to use it. [ 4 ] As of November 2012 it has the most market share of any layout engine at over 40% of the browser market share [ 5 ] —ahead of both the Trident engine used by Internet Explorer , and the Gecko engine used by Firefox . It is also used as the basis for the experimental browser included with the Amazon Kindle e-book reader , as well as the default browser in the Apple iOS , Android , BlackBerry 10 , and Tizen mobile operating systems. WebKit's C++ API provides a set of classes to display web content in windows, and implements browser features such as following links when clicked by the user, managing a back-forward list, and managing a history of pages recently visited.
HTML5 is a markup language for structuring and presenting content for the World Wide Web and a core technology of the Internet . It is the fifth revision of the HTML standard (created in 1990 and standardized as HTML 4 as of 1997) [ 2 ] and, as of December 2012 [update] , is a W3C Candidate Recommendation . [ 3 ] Its core aims have been to improve the language with support for the latest multimedia while keeping it easily readable by humans and consistently understood by computers and devices ( web browsers , parsers , etc.). HTML5 is intended to subsume not only HTML 4 , but XHTML 1 and DOM Level 2 HTML as well. [ 2 ]
WebSocket is a web technology providing full-duplex communications channels over a single TCP connection. The WebSocket protocol was standardized by the IETF as RFC 6455 in 2011, and the WebSocket API for in Web IDL is being standardized by the W3C . WebSocket is designed to be implemented in web browsers and web servers , but it can be used by any client or server application.

BitTorrent is a protocol that supports the practice of peer-to-peer file sharing and is used for distributing large amounts of data over the Internet . BitTorrent is one of the most common protocols for transferring large files and peer-to-peer networks have been estimated to collectively account for approximately 43% to 70% of all Internet traffic (depending on geographical location) as of February 2009 [update] . [ 1 ] In November of 2004 BitTorrent was responsible for 35% of all Internet traffic. [ 2 ] Programmer Bram Cohen designed the protocol in April 2001 and released the first available version on July 2, 2001. [ 3 ] Currently, numerous BitTorrent clients are available for a variety of computing platforms , [ 4 ] including an official one released by Bittorrent, Inc.
