Device Driver SystemDevice Driver System

Device driver Links an operating system and a device

Built-in Drivers vs. Installable Drivers Built-in drivers are installed by the platform manufacturer Installable drivers are third-party peripheral devices that

end users can connect to a windows CE-based platform Native Drivers vs. Stream Drivers

All of the device drivers managed by GWES are native device drivers

Device manager loads stream interface drivers when the system boots, if those drivers are listed in the registry

Monolithic Drivers vs. Layered Drivers Monolithic drivers implement interface directly in terms of

actions on the device they control Layered drivers separated the implementation into two

layers

InternationalizationInternationalization (con’t)(con’t)

Common practice for developing international software: Use a few target locales for initial development and testing Resource Localization: Strict or Non-strict

Translation Tips Avoid using vague words, colloquialisms, jargon, acronyms,

and abbreviations Use good grammar Avoid dynamic concatenation of different strings Avoid hard-cording file names in a binary files Avoid including text in image and icons

International Conventions Locales might have different conventions for expressing

information Locales might have different keyboard conventions
