TL;DR
A firmware update is the process of flashing newer embedded software onto a device's control hardware to patch security flaws, fix bugs, or unlock features, delivered over the air to phones and smart devices or via USB and service tools to appliances and routers. Interrupting one — power loss mid-flash — can brick the board, which is why technicians put laptops on charge and never reset a router mid-update.
What it means
A firmware update is the process of flashing newer embedded software onto a device's control hardware to patch security flaws, fix bugs, or unlock features, delivered over the air to phones and smart devices or via USB and service tools to appliances and routers. Interrupting one — power loss mid-flash — can brick the board, which is why technicians put laptops on charge and never reset a router mid-update. On networking gear, applying current firmware is the first step of any serious troubleshooting visit because so many faults are already-fixed bugs.
