Kurzbeschreibung Symbian Operating Systems (OS) represent the best operating systems for mobile devices. Symbian OS Smartphones have rapidly become mass market products; Symbian-based mobile phones now outnumber even the iPod. Mobile Operating Systems Using Symbian OS uses the Symbian OS System to discuss operating systems as they apply to mobile operating systems. The book contains a series of laboratories, based on software developed by Symbian OS devices, that readers can perform anywhere. Examples (both conceptual and applied to handhelds), end-of-chapter summaries, experiment-oriented questions and problems complete this comprehensive and interactive tutorial.
