Computer - Embedded system - Single Purpose
1 - About
An embedded system is a single purpose system where the function is built at hardware level whereas with a general purpose system a lot of function can be programmed without modifying its hardware.
Therefore, embedded systems typically do not have loaders, and instead the code executes directly from ROM.
Firmware may be the only program that will run on the system and provide all of its functions.
