A smartphone is a portable computer device that combines mobile telephone functions and personal computing functions into one unit. They are distinguished from older-design feature phones by their more advanced hardware capabilities and extensive mobile operating systems, which facilitate wider software, access to the internet, and multimedia functionality, alongside core phone functions such as voice calls and text messaging. Smartphones typically contain a number of metal–oxide–semiconductor (MOS) integrated circuit (IC) chips, include various sensors that can be leveraged by pre-installed and third-party software, and support wireless communication protocols. More recently, smartphone manufacturers have begun to integrate satellite messaging connectivity and satellite emergency services into devices for use in remote regions where there is no reliable cellular network.

A mobile phone is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area, as opposed to a fixed-location phone. The radio frequency link establishes a connection to the switching systems of a mobile phone operator, which provides access to the public switched telephone network (PSTN). Modern mobile telephone services use a cellular network architecture and therefore mobile telephones are called cellphones in North America. In addition to telephony, digital mobile phones support a variety of other services, such as text messaging, multimedia messaging, email, Internet access, short-range wireless communications, satellite access, business applications, video games and digital photography. Mobile phones offering only basic capabilities are known as feature phones; mobile phones which offer greatly advanced computing capabilities are referred to as smartphones.
In the first decade of the 21st century, the rise of digital media on the internet and computers as a central and primary means to record, distribute, store, and play music caused widespread economic changes in the music industry.

The rise of digital music consumption options contributed to several fundamental changes in consumption. One significant change in the music industry was the remarkable decline of conventional album sales on CD and vinyl. With the à la carte sales models increasing in popularity, consumers no longer downloaded entire albums but rather chose single songs.

They tend to use an embedded operating system with a small and simple graphical user interface, unlike large and complex mobile operating systems such as Android from Google or iOS from Apple. Their functions are limited compared to smartphones, which integrate the phone with an internet communications device.
