Part A
Define mechatronics.
Answer
Mechatronics is the synergistic integration of mechanical engineering, electronics, computer science, and control engineering in the design and manufacture of intelligent products and systems.
Outline real time operating system.
Answer
A Real-Time Operating System (RTOS) is an operating system designed to serve real-time applications that process data as it comes in, typically without buffer delays. It is characterized by deterministic timing, high reliability, and the ability to handle concurrent tasks with strict latency constraints.
