Software
what do you mean by embedded systems?can you give
a detailed description,applications and its benefits.
embedded means those that are externally fit into a system.(vaguely)
Now embedded systems are small progarms built into the hard ware to make them work.
simply the programs written and "embedded "into the hard ware(like cell phone ,washing machine,microwave oven.etc..)to make them automaticllay respond and do more things..
Hope it is somewhat clear...I tried to explain what I know..I am not into embedded systems anyway.

Think of embedded systems as having everything built in.
The hardware and software are tied into each other, (in bed) and you can't (normally) change one without changing the other.
Embedded systems are used all over the place.
Answer 1 concentrated on "consumer" applications.
They are just as widespread in industrial settings.
In fact, many of the sub-systems of your PC have embedded software. Your video card, modem, motherboard, CD drive, etc. have embedded "firmware".
Benefits of embedded systems include:
Reliability; since the user can't mess with the code, there is less to go wrong. Also, with all code in "firmware" there is no chance of a drive error.
Simpler programming; (yes, embedded programmers may argue this)you only have 1 set of hardware to contend with.
Improved functionality; most "embedded" applications replace mechanical controllers.
The more precise control and timeing from a microprocessor based system can greatly improve system performance and repetability.
Further, you can add extra features that were impossible or impractical for the mechanical system.
Fault tollerence; an embedded system can be readily set to "recover" from power outages, and related disruptions of operation.Cost; for high volume production, an embedded micro is a whole lot cheaper than a PC.
