A computer-based system integrated into a larger system, designed for a specific task, without human intervention.

Embedded systems have hardware, application software, and a real-time operating system (RTOS) to manage the application software.

An operating system designed for embedded systems, managing tasks according to a schedule to control latency.

An arrangement of units working together according to rules or a plan, where all components depend on each other.

Physical components in an embedded system, such as microcontrollers and sensors, which make up the physical system.

Specific software in an embedded system designed for a particular task; examples include a fire alarm or a car's engine control system.

A Java-based software used by programmers to create, compile, and upload programs to Arduino hardware.

Microcontroller-based physical platform often used in embedded systems, like an Arduino board.

A microcontroller-based, software-driven, reliable, real-time control system.
