Smartphone

A smartphone is a portable device that combines mobile telephone and computing functions into one unit. They are distinguished from feature phones by their stronger hardware capabilities and extensive mobile operating systems, which facilitate wider software, internet (including web browsing over mobile broadband), and multimedia functionality (including music, video, cameras, and gaming), alongside core phone functions such as voice calls and text messaging.

History

The development of the smartphone was enabled by several key technological advances. The explosion in the popularity of mobile telephony, particularly in the developing world, has led to a significant increase in the use of smartphones.

Design

Smartphones are typically pocket-sized and are able to be held in the hand, with screen sizes ranging from 100 to 150 millimeters (3.9 to 5.9 in). Some smartphones have screens that are larger than this, however, and may not be comfortable to hold in the hand.

Software

Smartphones run complete operating system software providing a platform for application developers. Mobile operating systems combine features of a personal computer operating system with other features useful for mobile or handheld use.

Applications

Smartphones have a wide variety of applications, which can be broadly divided into "personal" and "business" applications. Personal applications include games, social networking, and other entertainment applications, while business applications include email, calendar, and contact management applications.
