Embedded systems are not always standalone devices, in fact they comprise of small, computerized parts within a larger device that serves a more general purpose. With out these systems it would have been impossible to carry out specific task. This helps in improving real-time performance constraints that must be met by latest technologies.
Traffic control, factory control, air traffic control and is also used in telephone switches. In order to route data, they make use of network bridges and routers along with computer network. Of late, its usage has been found in MP3players, DVD players, digi Cameras and advanced video games. Electronic gadgets such as PDAs, as we all know it ‘the Personal Digital Assistants’.
Its usage has also been found in the household appliances. Household appliances, such as microwave ovens, washing machines and dishwashers, are including embedded systems to provide flexibility, efficiency and features. Advanced HVAC systems use networked thermostats to more accurately and efficiently control temperature that can change by time of day and season. Home automation uses wired- and wireless-networking that can be used to control lights, climate, security, audio/visual, surveillance, etc., all of which use embedded devices for sensing and controlling. Latest technologies improve real time performance.
