Analogy
Like translators that let two people speaking different languages understand each other.
Definition
Low‑level programs that enable operating systems to communicate with hardware devices (e.g., GPUs, network cards), facilitating blockchain node performance and connectivity.
Key Points Intro
Device drivers bridge the gap between OS and hardware capabilities.
Key Points
Hardware abstraction: Exposes device functions via OS APIs.
Kernel modules: Run in privileged mode for performance.
Version compatibility: Must match OS and hardware firmware.
Performance tuning: Optimize throughput and latency.
Example
Technical Deep Dive
Drivers register with the OS kernel, implement ioctl handlers, and manage DMA for high‑speed data transfer. Updates often include performance patches and security fixes.
Security Warning
Vulnerable drivers can be exploited for kernel‑level attacks; apply vendor patches promptly.
Caveat
Incorrect driver versions can cause system instability or degraded performance.
