This document discusses computer game platforms, technologies, and operating systems. It begins by recapping platforms like arcade, console, PC, mobile, and television that were covered previously. It then defines an operating system as software that provides an interface between hardware and applications, allowing them to communicate. Different operating systems are dependent on specific hardware architectures. The document outlines the history of operating systems from early machines with no OS to modern graphical user interfaces. It compares operating systems like Windows, Mac OS, and those for handheld and mobile devices. Finally, it mentions device drivers and software elements as part of an upcoming assignment.

1. Computer Game Platforms & TechnologiesWeek 4Introduction to Software:Operating Systems

2. So Far We Have..Looked at a series of Game Platforms (Arcade, Console, PC, Mobile & Television)Looked at a series of Games for each

3. Operating SystemsWhat is an Operating System?

4. Operating SystemsGives the user the interface to interact with the various hardware componentsProvides a link between the hardware & software of the platform being used, effectively allowing them to communicate between each other

5. Operating SystemsPlatform dependencyNot all applications run on all platformsCan be a factor when developing a gameImportance of developing multi-platformOperating Systems are platform dependant on the grounds of hardware architecture (e.g. CPU, RAM)

6. Operating SystemsHistory of Operating SystemsEarly Machines had no O/SExecuted pre-defined commands (punched tape)Single task at a timeControlled by Toggles

7. Operating SystemsHistory of Operating SystemsMainframesOperating Systems created for specific machinesApplications needed to be retested or recreated

8. Operating SystemsHistory of Operating SystemsCommand Line (80’s)  GUI (84)

9. Operating SystemsWhat is the difference between the NES & Nintendo Wii Operating Systems?

12. Operating SystemsGraphical User Interface (GUI)Windows & Mac O/S are prime examples of GUI’sRather than using specified commands to access and manipulate files, the user can graphically select what they want – effectively making it easier to interact with the environmentFiling Cabinet == Folders within Windows
