Any electronic system that uses a CPU chip, but that is not a general-purpose workstation, Such systems generally use microprocessors, or they may use custom-designed chips or both. They are used in automobiles, planes, trains, space vehicles, machine tools, cameras, consumer and office appliances, cellphones, PDAs and other handhelds as well as robots and toys. The uses are endless, and billions of microprocessors are shipped every year for a myriad of applications. Although there are embedded versions of popular operating systems, low-cost consumer products can use chips that cost less than a dollar and have very limited storage for instructions. In such cases, the OS and application may be combined into one program.

A combination of computer hardware and software and perhaps additional mechanical or other parts designed to perform a dedicated function. In some cases embedded systems are part of a larger system or product as in the case of an antilock braking system in a car. Contrast with general-purpose computer.
Embeded system means it is the collection of software and hardware and other mechanical part and electronics equipement.the user can not interact with this embeded system . it is meant for only doing special type of function.

embedded systems simply means a system with both software and the hardware .it is meant for some special functions .it is used in the automobiles planesetc ad generally works efficiently.
an embedded system is a software and a hardware system which contains all the controls embedded on one system. it controls all the functions of the entire component systems.
e.g. a aircraft control system missile launching.
in these type of systems there is some time constraints and if there is failure of one component the entire system fails.
A system which is designed or built using the microprosessor microcontroller memory & input/output ports i.e hardware parts is known as an embeded system.
