👉 Firmware fluid refers to the dynamic, self-updating software that resides within the hardware of embedded systems and devices, enabling them to adapt and evolve over time. Unlike traditional firmware, which is static and requires manual updates, firmware fluid allows devices to receive new features, security patches, and performance improvements without human intervention. This capability is achieved through mechanisms like over-the-air (OTA) updates, enabling devices to download and install software changes wirelessly, ensuring they remain secure and efficient in a rapidly changing technological landscape. Firmware fluid thus enhances the longevity, reliability, and functionality of devices by providing a continuous stream of updates tailored to their specific needs.
