Why is in-system programming considered a defining method for software deployment in microcontrollers?
Answer
It allows firmware to be flashed directly into the chip permanent memory.
Software deployment in the microcontroller domain centers on in-system programming, where compiled firmware is written directly into the chip's non-volatile memory, such as Flash or ROM. This method contrasts with older computing approaches that involved loading software from external drives. By flashing code directly onto the controller, the device becomes a dedicated, efficient appliance controller, solidifying its role in embedded electronics rather than serving as a general-purpose computing platform.
