With the increase in demand for mobility, the popularity of mobile devices continues to grow. A mobile device is any device that is hand-held, light, and typically uses a touchscreen for input. Like a desktop or laptop computer, mobile devices use an operating system to run applications (apps), games, and play movies and music. Some examples of mobile devices include Android devices, such as the Samsung Galaxy tablet and Galaxy Nexus smartphone, and the Apple iPad and iPhone.

To facilitate mobility, mobile devices use many different wireless technologies. Many mobile device components, operating systems, and software are proprietary. It is important to become familiar with as many different mobile devices as possible.

You may be required to know how to configure, maintain, and repair various mobile devices. Some of the knowledge you acquire about desktop and laptop computers will help you; however, there are important differences between these technologies.

Mastering the skills necessary to work on mobile devices is important to your career advancement. This chapter focuses on the many features of mobile devices and their capabilities, including configuration, synchronization, and data backup.
