Embedded Systems
Final Exam Questions
Course Introduction
Embedded Systems is a course that introduces students to the design, development, and application of specialized computing systems that are integrated into larger devices and products. Covering both hardware and software aspects, the course explores microcontrollers, real-time operating systems, input/output interfacing, and communication protocols. Students will gain hands-on experience in programming embedded devices, understanding system constraints, optimizing performance, and ensuring reliability in application-specific environments such as consumer electronics, automotive systems, and industrial control. Through laboratory work and projects, students develop practical skills in building and troubleshooting embedded systems.
