Which feature is primarily associated with 'Embedded Controllers'?

Embedded controllers are specifically designed to perform dedicated tasks within machinery, often in real-time. They are integrated into hardware systems to manage various functions like controlling motors, managing sensors, and facilitating communication within devices. The primary characteristic of embedded controllers is their ability to process data directly within the machinery, which allows for immediate response and efficient operation without the need for external processing resources.

While features like redundancy options, cloud storage capabilities, and graphic user interfaces can be relevant in a broader context of automation or control systems, they are not defining features of embedded controllers. Redundancy might relate more to ensuring system reliability in larger systems, cloud storage pertains to data management strategies, and graphic user interfaces focus on user interaction. However, the essence of embedded controllers lies in their capability to execute tasks directly within the hardware they control.
