Embedded Operating Systems (OS) is a specialized skill related to software. It involves designing and implementing operating systems for specific hardware platforms or embedded systems. Embedded OS are typically used in devices that are not intended to be general-purpose computing devices, such as appliances, industrial control systems, medical devices, and embedded systems. This skill requires knowledge of programming languages, operating system architecture, and hardware interfaces. Engineers with this skill are responsible for ensuring that the embedded system operates efficiently, securely, and reliably.
