SMART PHONES - INVENTION THAT CHANGED THE WORLD

2.
A smartphone is a cellular telephone with an integrated computer and other features not originally
associated with telephones, such as an operating system, web browsing and the ability to run software
applications.
The first smartphone was IBM's Simon, which was presented as a concept device -- rather than a consumer
device -- at the 1992 COMDEX computer trade show. It was capable of sending emails and faxes, as well as
keeping a calendar of events for the user, as opposed to simply making calls and sending messages.
Consumer smartphones evolved away from personal digital assistants (PDAs) around the turn of
the 21st century when devices such as the PalmPilot began to include wireless connectivity.
Several manufacturers, including Nokia and Hewlett Packard, released devices in 1996 that were
combinations of PDAs and typical cellphones that included early operating systems (OSes) and
web browsing capabilities. BlackBerry released its first smartphones in the mid-2000s, and they
became very popular with consumers and in the enterprise.

Cellphone vs. smartphone
A cellphone is simply a telephone that doesn't need a landline connection. It enables the user to make and
receive phone calls. Some cellphones also offer text messaging.
A smartphone has more advanced features, including web browsing, software applications and a mobile OS. In
turn, a smartphone also offers capabilities such as support for biometrics, video chatting, digital assistants and
much more.
Still, there is no standard definition that clearly delineates a smartphone; many devices marketed simply as
cellphones offer similar features to those marketed as smartphones.
Important features
One of the most important features of a smartphone is its connection to an app store. An app store is a
centralized portal where users can search for and download software applications to run on their phones. A
typical app store offers thousands of mobile apps for productivity, gaming, word processing, note-taking,
organization, social media and more.
