Embedded system is a microprocessor based system ussed for 
a specific jobs only. for example in Washing Machines and 
Microwave ovens.

Lookong deep they have devices like RAM,Timer Counters, 
Serial DATA Transmission, etc in-built which are however 
externally attached in the pc's as peripheral IC's

In a system,a device is incorporate into that system then it
process and controls the system is called  EMBEDDED.

Embedded systems control many of the common devices in use 
today.embedded as part of a complete device including 
hardware and mechanical parts.Some embedded systems are 
mass-produced, benefiting from economies of scale

Embedded systems is that they are devices used to control, 
monitor or assist the operation of equipment, machinery or 
plant.

embdeed is a combination of hadware and software or other
wise embedding a soft ware in a hardware

the device developed with the help of microcontrlor is 
known as embeded system.the processor used in this system 
is  8085 or 8086.we write a program of  microcntrolr 
according to need,and store this program in this 
microcontrolar.eg Washing Machines,trafic control signal.
programing of these two r different.etc..........
