Built-in memory

The device has its own built-in memory.

Almost every sophisticated electronic device has a certain amount of memory, but here we specifically refer to permanent memory. This type of memory is ideal for long-term data storage, ensuring information is retained even during power outages. Its presence enables the device to operate autonomously, storing training logs, individual settings, and other essential data without the need for communication with other devices.
