  Embedded Systems:      a microprocessor-based computer hardware system with software that is designed to perform a dedicated function, either as an independent system or as a part of a large system .     An embedded system is a combination of computer hardware and software designed for a specific function. Embedded systems may also function within a larger system. The systems can be programmable or have a fixed functionality. Why?  performance Small size  Ease of management  Cost effective Characteristics Speed Accuracy Reliability  Adaptability  Size and weight  Power dissipation Features Do specific tasks Not always standalone devices Limited resources and memory  No screen  Maximum performance for minimum size Efficiency  Reliability  Examples Smart watches  Traffic light controller  Medical equipment  Remote control car Washing machine  Train  Mobile phone- telecom Equipments...
