Symbian Operating System PPT
Symbian OS Presentation Transcript:1. 1.5 billion mobile phone users (ITU) Mobile device capabilities are significantly advanced than those in the past Key question Are we going to face the same level of threat to security of mobile devices as that of in desktop environment?
2. Operating System (OS) Process Management Memory Management File Management I/O Management Networking
3. Real Time Operating System (RTOS) Characterized by timing constraints Mobile Operating System (Mobile OS) RTOS running on a mobile device
4. Symbian established as a private independent company in June 1998, owned by Ericsson, Nokia, Motorola and Psion. Symbian is a software licensing company that develops and supplies the advanced, open, standard operating system – Symbian OS – for data-enabled mobile phones.

8. Small and mobile, but always available Mobile phones are both small and, by definition, mobile. This creates high user expectations. Addressing the mass-market Reliable. Data loss in a personal mobile phone causes a loss of trust between the user and the phone
9. Handling occasional connectivity Mobility constraints generally make a wireless connection preferable - whether wide area (using wireless telephony) or personal area (such as infrared or Bluetooth). Wireless connectivity is patchy, caused by different protocols Open platform An operating system for the mass-market must be open for third-party development.
