An embedded system is a special-purpose computer system designed to perform one or a few dedicated functions,[1] often 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 different tasks depending on programming. Embedded systems control many of the common devices in use today.

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 systems are mass-produced, benefiting from economies of scale.

Physically, embedded systems range from portable devices such as digital watches and MP4 players, to large stationary installations like traffic lights, factory controllers, or the systems controlling nuclear power plants. Complexity varies from low, with a single micro controller chip, to very high with multiple units, peripherals and networks mounted inside a large chassis or enclosure.

In general, "embedded system" is not an exactly defined term, as many systems have some element of programmability. For example, Handheld computers share some elements with embedded systems - such as the operating systems and microprocessors which power them - but are not truly embedded systems, because they allow different applications to be loaded and peripherals to be connected.

any electronic system inbuilt with intelligence can be called as embedded system.

for example if microwave oven is inbuilt with microcontroller can be called as embedded system. An embedded system has historically been defined as a single function product where the intelligence is embedded in the system. It could be anything from a dishwasher to a hearing aid, if that product includes a microprocessor and software. Many of today's embedded systems are looking more like PCs with user interfaces, touchscreens, displays, keypads and more. Still, these are not general function systems but are designed to perform very specific functions.

Embedded Software can be very short and simple, such as lighting controls running on an 8-bit microprocessor and a few kilobytes of memory. It can also be sophisticated in applications such as in airplanes, missiles and process control systems.
