2. Introduction to embedded system
What is embedded?
Fix firmly In a surrounding mass.
What is embedded system?
embedded system is a special purpose system in which the computer is completely encapsulated by the device it controls.
an embedded system performs pre-defined tasks, usually with very specific requirements. They are designed such that their size small and cost is also low.

3. History:-
The Apollo Guidance Computer, the first recognizably modern embedded system developed by Charles Stark Draper at the MIT Instrumentation Laboratory .

4. Why to use Embedded system are used to reduce the size of application.
It performs a particular application very efficiently
It costs less, it is accurate and reliable.

5. Examples:- Automatic teller machine. (ATM)
Avionics (they are the internal guidance systems present in aircraft and missiles.
Telephones,printers, calculators
In automobiles:-engine controller
Home automations:-air conditioner
House hold applications:-micro wave ovens, tv, washing machine, dvd players etc.
