Advanced Topic 42 of 51 Operating Systems
Device Drivers
Modules that let the OS talk to specific hardware.
How it works
A driver is kernel code that translates generic OS requests into device-specific commands and handles the device's interrupts.
Where it is used
GPU and network drivers.
Common pitfall
Driver bugs are a leading cause of crashes since they run in kernel mode.
Where it fits in the course
Device Drivers is topic 42 of 51 in Operating Systems, rated Advanced. It follows I/O Management. The next topic is Booting Process.
