What Is Embedded System?

Embedded System is combination of software and hardware and Designed to Perform Specific task.

In general embedded system is not an exactly define term,as many systems have some element of Programmability. For example handheld
computers share some elements with embedded sytem-Such as the operating systems and microprocessors which power them-but are not truly embedded system because they allow different application to be loaded and peripherals to be connected.
An embedded system is a specific-purpose computer system designed to perform one or a few dedicated function, sometimes with real-time computing constraints.It is usually embedded as part of a complete device including hardware and mechanical parts.In contrast a general-purpose computer such as a personal computer can do  many tasks depending on programing Embedded system have become very important today as they control many of the common devices we use.


Since the Embedded system is dedicated to specific tasks,design engineers can optimize it ,reducing the size and cost of the product,or increasing the reliability and performance.Some embedded system are mass-produced,benefiting from economies of scale.

Physically,Embedded system range from portable devices such as digital watches and mp3 players ,to large stationary installations like traffic lights, factory controllers,or the system controlling nuclear power plants complexity varies from low,with a single networks mounted inside a large chassis or enclosure.

Certain operating system or language platforms are tailored for the Embedded market,such as Embedded Java and windows XP embedded. However some low-end consumer products use very.

Operating system both part of a single program,with the application and operating system both part of a single program. The program is written permanently into the system memory in this case ,rather than being loaded into RAM as programs on a personal computer.
