Embedded System
Embedded system is combination of hardware & software for specific application.
Embedded system means the processor is embedded into that application.
An embedded product uses a microprocessor or microcontroller to do one task only.
In an embedded system, there is only one application software that is typically burned into ROM.



How an embedded system works..
It works with the help of both the hardware and software requirements
Hardware: processor, memories, peripherals, power supply etc..,
Software: assembly language program (ALP) like c, c++ ..,



Types of embedded systems
Simple embedded system
ex: small electrical equipments completes its work with in the approximated time
Complex embedded system
ex: used in military missiles for target based system
