The Smartphone is known as an intelligent phone because they are electronic devices that resemble a cell phone but are more like a mobile personal computer. They do, however, enable you to communicate as with a regular cell phone.
They share a set of features such as a touch screen, Wi-Fi, Bluetooth, 3G, internet and more. Many people use them to send email and access the internet.
What purpose does a Smartphone serve?
With a Smartphone you can do everything at once, including receive calls, check your calendar while you watch some videos in Media Player, or while you sync your device with others, and all this without interrupting any of the tasks. It is almost the same as a computer, where you can open windows and work on all simultaneously, and not like a conventional telephone, where in order to check your schedule you must stop listening to the call.
In short, a Smartphone is something like a mobile phone, but with much more potential, and almost seems designed for those addicted to email and internet access, or those who are entrepreneurs.
