How Are Smartphones Different From Cellular Phones?

While we all know what cellular phones are, we do not always know how to differentiate them from Smartphones.
Smartphones have mobile operating system.
You can think of a Smartphone like a mini computer that can also make and receive calls. Though there lacks an industry-standard definition of a Smartphone, the simplest way to tell a cell phone apart from a Smartphone is to determine whether or not the gadget has a mobile operating system.
A mobile operating system is much like what is powering your personal computer at work or at home. In the mobile industry, though, the software goes by different names. While cell phones do not have operating systems at all, Smartphones can be powered by:
The iPhone OS comes from other operating systems (OS) that are related to Unix. Google’s Android and Palm’s WebOS are built on top of Linux. Smartphones can usually view and sometimes edit documents (i.e. from Microsoft Office) while cell phones cannot.
While many cellular phones now have full QWERTY keyboards, this is a basic requirement for Smartphones. The keyboard is the same as computer’s keyboard. On a mobile phone, it can come in the form of hardware (a physical but small keyboard) or software (tapping digital keys on a touch screen such as with the iPhone).
