Definition
Device drivers are specialised software that allow the operating system to communicate with hardware devices. Each device requires a driver to translate OS commands into actions that the device can perform.
Key Point
Purpose of Device Drivers:
• Abstract hardware complexity from the OS
• Translate generic OS commands to device-specific instructions
• Handle device-specific features and optimizations
• Enable plug-and-play functionality
Issues:
• Incompatible or outdated drivers cause system instability
• Missing drivers prevent hardware from functioning
• Driver conflicts can cause crashes
