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.

A mobile application software or mobile app is an application software designed to run on mobile devices such as smartphones and tablet computers.

Most such devices are sold with several apps bundled as pre-installed software, such as a web browser, email client, calendar, mapping program, and an app for buying music or other media or more apps.

Some pre-installed apps can be removed by an ordinary uninstall process, thus leaving more storage space for desired ones.

Where the software does not allow this, some devices can be rooted to eliminate the undesired apps.

A machine is a tool containing one or more parts that uses energy to perform an intended action.

Machines are usually powered by chemical, thermal, or electrical means, and are often motorized.

Historically, a power tool also required moving parts to classify as a machine.

However, the advent of electronics has led to the development of power tools without moving parts that are considered machines.
