用法筆記

Firmware is uncountable — do not write 'a firmware'. Use 'a firmware update' or 'a piece of firmware' for a specific instance. The verb 'flash' is also common: 'flash the firmware' means to install or update it.

❌I need to buy a firmware for my phone.
✅I need to update the firmware on my phone.
💡Firmware is uncountable and is rarely 'bought'; it is updated or installed.
❌My camera needs a new firmware.
✅My camera needs a firmware update.
💡Use 'firmware update' rather than treating 'firmware' as a countable noun.
