The kind of system software preinstalled on electronic products like blenders, automobiles, and televisions is typically firmware. Firmware is specialized software embedded in the hardware to control and manage the device's functions.
For example, smart TVs also have operating systems such as Android TV, Tizen OS (used by Samsung), Fire TV, and others, which are integrated into the device firmware to provide the user interface and additional functionalities like app access and voice control. However, at the most fundamental level across such electronic products, it is firmware that is preinstalled to ensure the device operates correctly.
