1 Robin Estabrooks Computer Science 1631, Winter 2011

2 Terms You’ll Need to Know  Operating System: collection of software that directs a computer's operations, controlling and scheduling the execution of other programs, and managing storage, input/output, and communication resources.  Kernel: central component of most computer’s OS; it’s a bridge between applications and the actual data processing done at the hardware level Application Developer: those who create and maintains software through the World Wide Web Third Party Application: when application from one program can be played on another

3 Terms You’ll Need to Know Middleware: connects software components or applications. Software consists of a set of services that allows multiple processes running on one or more machines to interact Interface Component: an element of a graphical user interface (GUI) that displays an information arrangement changeable by the user, such as a window or a text box Software Stack: a set of software subsystems or components needed to deliver a fully functional solution Application Platform: hardware architecture or software framework (including application frameworks), that allows software to run

4 The Smartphone  Considered to be a hand held computer combined with a mobile phone  The Smartphone's key component is its operating system (OS)  Manages the hardware and the software resources  Platform for application developers

5 History  First attempt of Smartphone in 1992 from IMB  This was the foundation for present day Smartphones  Features: email, fax, world clock, calendar, calculator, address book, touch screeen  Problem: size of a brick

6 History  Second attempt in 1996 by Nokia  First Smartphone with an operating system  Problem: So expensive no one could buy it

7 History  2001: Handspring released the Palm OS Treo  Featured wireless web browsing, email and contact organiser  First to introduce third party application  A year later: the launch of the original Smartphone  The point where Smartphone reached wide market

8 History  2007: Apple released the iPhone  Revolutionised web browsing  Year later introduced its application store  Started a trend that other Smartphone companies followed

9 Companies  Symbian  Operating system for more than 100 different models of phones  Kernel and middleware components  Application platforms: S60, UIQ, and MOAP  Dominant in market at present, but other companies will hold more shares in the future

10 Companies  Linux  Community of developers rather than central company  More processors than any other operating system  Linux is organic OS: developers constantly changing/updating, platforms based on Linux code is very different from one another.  Some Smartphone companies find the risk too great to invest in Linux

11 Companies  Windows Mobile  Includes entire software stack from kernel to application interface  Strength lies in compatibility with the Microsoft Office suite of programs.  Java  Includes everything from kernel to user interface framework  Not made a huge impact in the marketplace  May in future

12 Companies  Garnet OS  Formerly known as Palm OS  Combines a Linux- based foundation with applications written for the old Palm OS  Unique Operating Systems  Apple’s iPhone uses OS X  Blackberry: has its own proprietary OS

13 The Future of the Smartphone  Technology always changing  Smartphone will change dramatically in the next 5 years

14 The future of the Smartphone  Advances could be made in areas like:  PC Replacement: full movement to things like the iPad  Connected Devices: connection to the internet anywhere  Gaming Expands Further: better graphics and faster processor  Social Networking and connections: communicating more simple
