iOS (formerly iPhone OS) is a mobile operating system created and developed by Apple Inc. exclusively for its hardware.

It is the operating system that presently powers many of the company's mobile devices, including the iPhone, iPad, and iPod Touch.

It is the second most popular mobile operating system globally after Android.

iPad tablets are also the second most popular, by sales, against Android since 2013.

Android is a mobile operating system developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets.

Android's user interface is mainly based on direct manipulation, using touch gestures that loosely correspond to real-world actions, such as swiping, tapping and pinching, to manipulate on-screen objects, along with a virtual keyboard for text input.

In addition to touchscreen devices, Google has further developed Android TV for televisions, Android Auto for cars, and Android Wear for wrist watches, each with a specialized user interface.

Variants of Android are also used on notebooks, game consoles, digital cameras, and other electronics.

In the context of cryptocurrency mining, a mining pool is the pooling of resources by miners, who share their processing power over a network, to split the reward equally, according to the amount of work they contributed to solving a block.

A "share" is awarded to members of the mining pool who present a valid proof of work that their miner solved.

Mining in pools began when the difficulty for mining increased to the point where it could take years for slower miners to generate a block.

The solution to this problem was for miners to pool their resources so they could generate blocks more quickly and therefore receive a portion of the block reward on a consistent basis, rather than randomly once every few years.

The World Wide Web (abbreviated WWW or the Web) is an information space where documents and other web resources are identified by Uniform Resource Locators (URLs), interlinked by hypertext links, and can be accessed via the Internet.

English scientist Tim Berners-Lee invented the World Wide Web in 1989.

He wrote the first web browser computer program in 1990 while employed at CERN in Switzerland.

The Web browser was released outside of CERN in 1991, first to other research institutions starting in January 1991 and to the general public on the Internet in August 1991.
