One of the largest examples of mobile computing in modern-day life is the smartphone. They are all around us. Whether it's an iPhone, Android phone, Windows phone, Blackberry, etc.; it's hard to go anywhere without seeing someone's face "glued" to a smartphone. I think the term smartphone tends to fool a lot of not-so-tech-savvy consumers though. They hear the word smartphone and think of it as phone with additional capabilities; when what it's truly a mobile computing device.
Smartphones are essentially just very small versions of computers. Just like any other computer, smartphones have a CPU, RAM, input devices (keyboard, touchscreen, trackball, etc.), a display, wireless capabilities, and many other features that a normal computer has. I think another term that can confuse some end-users is the term "app." An app, or application, is really just a program that accesses the computing resources of a mobile device in order to accomplish a certain task. Just like installing a program on your laptop, you install an app on your smartphone. Even though the terms are a bit different, don't let them fool you; that smartphone in your pocket is really just a tiny computer!
