Android is an open-source, Linux-based operating system for mobile devices, such as smartphones and tablets. It was developed by Android Inc. and later purchased by Google in 2005. Android is the most popular mobile operating system in the world, with more than 2.5 million daily active users.
Android was first unveiled in 2007, with the first commercial iPhones and Android-based phones shipping in October of that year. The first version of Android was called “Cupcake” and was released in 2009, with subsequent major Android updates released in 2010 (Froyo), 2011 (Gingerbread), 2012 (Ice Cream Sandwich), 2013 (Jelly Bean), and 2014 (KitKat). The current version of Android, Marshmallow (6.x), was first released in October 2015.
Android is built on top of the Linux kernel and is open-source, meaning anyone can use its code to create new applications, modify existing ones, or even create new versions of Android. Android devices come with a variety of built-in applications, including a web browser, email client, and media player. Android also has a large selection of apps available in the Google Play Store, ranging from games to productivity applications.
Android is becoming increasingly popular among device manufacturers, with Samsung, LG, and HTC leading the market. While most Android phones run a “stock” version of the operating system, other manufacturers have “skinned” versions that offer a slightly different look and feel.
Android has made significant advances over the past few years, and developers continue to create innovative applications and services for the platform. Android continues to be one of the most popular operating systems available, offering a wealth of features and apps that can provide a great user experience.
