Firmware

What Is Firmware?

Short definition:
Firmware is software built directly into hardware devices to control how they function.

What this actually means for a business:
Devices like routers, firewalls, and printers rely on firmware to operate properly and securely.

Common misconception:
Many assume devices “just work” forever. In reality, firmware needs updates to fix bugs and security issues.

When this matters:
If devices become unstable, slow, or vulnerable to security threats.
