IntroductionArchitectureControls and compound controlsActive ObjectsLocalizationSecurityFuture Scope
Nokia’s mobile operating systemOpen sourceExtension of EPOCTarget Platforms (x86 and ARM) RISC
processorsDesigned in C++Licensed under EPLTrue Microkernel OSStandards – S60, UIQ, MOAP
Support for vast variety of languages like Perl Python J2ME VB OPL
Designed Keeping These factors in mind Integrity and security of User data Faster response time All resources are scarce
Event based Active Objects Observer Design Pattern
Callback mechanismCooperative MultitaskingUse of asynchronous requests.ThreadingActive SchedulerMultitasking in a same threadPossible to perform preemptive multitasking.
