Android (operating system)

Android may be a mobile software (OS) supported the UNIX operating system kernel and presently developed by Google. With a interface supported direct manipulation, golem is meant primarily for touchscreen mobile devices like smartphones and pill computers, with specialised user interfaces for televisions (Android TV), cars (Android Auto), and gliding joint watches (Android Wear). The OS uses bit inputs that loosely correspond to real-world actions, like swiping, tapping, pinching, and reverse pinching to control on-screen objects, and a virtual keyboard. Despite being primarily designed for touchscreen input, it additionally has been employed in game consoles, digital cameras, regular PCs (e.g. the H.P. Slate 21) and alternative physical science.

Android is that the most generally used mobile OS and, as of 2013, the very best commerce OS overall. golem devices sell quite Microsoft Windows, iOS, and waterproof OS X devices combined, with sales in 2012, 2013 and 2014 near the put in base of all PCs. As of July 2013 the Google Play store has had over a meg golem applications ("apps") printed, and over fifty billion applications downloaded. A developer survey conducted in April–May 2013 found that seventy one of mobile developers develop for golem.At Google I/O 2014, the corporate unconcealed that there have been over one billion active monthly golem users, up from 538 million in Gregorian calendar month 2013.

Android's ASCII text file is discharged by Google underneath open supply licenses, though most golem devices ultimately ship with a mixture of open supply and proprietary package, together with proprietary package developed and authorised by Google. ab initio developed by golem, Inc., that Google backed financially and later bought in 2005, golem was unveiled in 2007 together with the foundation of the Open telephone Alliance—​a pool of hardware, software, and telecommunication corporations dedicated to advancing open standards for mobile devices.

Android is popular technology corporations that need a ready-made, cheap and customizable software for sophisticated devices.Android's open nature has inspired an oversized community of developers and enthusiasts to use the ASCII text file code as a foundation for community-driven comes, that add new options for advanced users or bring golem to devices that were formally discharged running alternative operational systems. The operational system's success has created it a target for patent legal proceeding as a part of the questionable "smartphone wars" between technology corporations.

Java (programming language)

Java may be a all-purpose programing language that's cooccurring, class-based, object-oriented, and specifically designed to possess as few implementation dependencies as attainable. it's supposed to let application developers "write once, run anywhere" (WORA), which means that code that runs on one platform doesn't have to be compelled to be recompiled to run on another. Java applications square measure usually compiled to bytecode which will run on any Java virtual machine (JVM) despite laptop design. Java is, as of 2015, one in every of the foremost common programming languages in use, significantly for client-server internet applications, with a reportable nine million developers.Java was originally developed by James goose at Sun Microsystems (which has since incorporated into Oracle Corporation) and discharged in 1995 as a core part of Sun Microsystems' Java platform. The language derives abundant of its syntax from C and C++, however it's fewer low-level facilities than either of them.




The original and reference implementation Java compilers, virtual machines, and sophistication libraries were originally discharged by Sun underneath proprietary licences. As of might 2007, in compliance with the specifications of the Java Community method, Sun relicensed most of its Java technologies underneath the antelope General Public License. Others have conjointly developed different implementations of those Sun technologies, like the antelope Compiler for Java (bytecode compiler), antelope category path (standard libraries), and IcedTea-Web (browser plugin for applets).
