It has been a device vital to communication since its inception, and has continued to evolve as technology allowed.

A smartphone is a cellular phone with extra computing functionality and connectivity capabilities. While many cellular phones can run a set of simple applications that come pre-installed on the device, smartphones allow the user to download and install applications of widely varying complexity. Many smartphones double as portable computing devices, providing the user with business and personal communication functionality from any location.
