A smartphone refers to a cellphone that combines the functions of a regular cellphone with features of a computer.
Smartphones thus not only allow phone conversations and text messaging. They can also be used to take pictures and videos, to surf the web and play music and videos - to name just a few examples. Modern smartphones can be operated by touching the phone's screen.
Today, everyone knows what a smartphone is, even the very young. It's a global phenomenon. And yet it's only a decade since these talented little gadgets first hit our markets. No other form of technology has so rapidly altered our lives in such a short period of time. And it all began with the iPhone.
