Google Play (previously Android Market) is a digital distribution service operated and developed by Google.

It serves as the official app store for the Android operating system, allowing users to browse and download applications developed with the Android software development kit (SDK) and published through Google.

Google Play also serves as a digital media store, offering music, magazines, books, movies, and television programs.

It previously offered Google hardware devices for purchase until the introduction of a separate online hardware retailer, Google Store, on March 11, 2015.

A Chromebook is a laptop or tablet running the Linux-based Chrome OS as its operating system.

The devices are primarily used to perform a variety of tasks using the Google Chrome browser, with most applications and data residing in the cloud rather than on the machine itself.

Some Chromebooks can also run Android apps.

A laptop, also called a notebook computer or just notebook, is a small, portable personal computer with a "clamshell" form factor, having, typically, a thin LCD or LED computer screen mounted on the inside of the upper lid of the "clamshell" and an alphanumeric keyboard on the inside of the lower lid.

The "clamshell" is opened up to use the computer.

Laptops are folded shut for transportation, and thus are suitable for mobile use.

Its name comes from "lap", as it was deemed to be placed for use on a person's lap.

Although originally there was a distinction between laptops and notebooks, the former being bigger and heavier than the latter, as of 2014, there is often no longer any difference.

Laptops are commonly used in a variety of settings, such as at work, in education, in playing games, Internet surfing, for personal multimedia and general home computer use.

A mobile app is a computer program designed to run on a mobile device such as a phone/tablet or watch.

Productivity software (also called personal productivity software or office productivity software) is application software used for producing information (such as documents, presentations, worksheets, databases, charts, graphs, digital paintings, electronic music and digital video).

Its names arose from the fact that it increases productivity, especially of individual office workers, from typists to knowledge workers, although its scope is now wider than that.

s, which brought word processing, spreadsheet, and relational database programs to the desktop in the 1980s, are the core example of productivity software.

They revolutionized the office with the magnitude of the productivity increase they brought as compared with the pre-1980s office environments of typewriters, paper filing, and handwritten lists and ledgers.

Some 78% of "middle-skill" occupations (those that call for more than a high school diploma but less than a bachelor's degree) now require the use of productivity software.

In the 2010s, productivity software has become even more consumerized than it already was, as computing becomes ever more integrated into daily personal life.
