In your life,There are many Electronic devices perform useful tasks.Basically a washing
machine can be taken as in that category.It performs a specific task which are clean clothes,controlling water flow etc…You may not think about the technical part.So that tasks are done by an Embedded system.
See the most accurate definition of an embedded system.
“An Embedded System is a microprocessor based system that is built to control a function or a group of functions and is not designed to be programmed by the end user”.
Now you can get a simple idea about an embedded system.Nowadays there are many complex devices.For an example a robot in a car factory.
Parts in an Embedded Systems.
* Processor can provide the processing power needed to perform the tasks within the system.
*Memory is an impotent part of an Embedded System.It provides a storage for the software that will run and data such as program variables intermediate results.
*Peripherals do the communication part with the outside world.
*Software
*Algorithms
