embedded system also include microcontroller.
An elevator is an electronic device that transports people or goods in a vertical motion. A microcontroller embedded in the control system of an elevator is used to control the elevator's mechanisms.

8051 microcontroller and Embedded System By Mazidigood for basic programms & hardware settings.pgms covered are LCD, KEYPAD, Temperature sensors etc.- nilesh
A PDA is a complete handheld portable computer system, with all the input and output devices needed for a user to interact with it. A microcontroller is just one chip. It needs to be mounted on a circuit board and connected to input and output devices before it can do anything. Microcontrollers are usually used as a part of an embedded control system
We don't have to bother much about hardware.Also it will take only less effort to change from one microcontroller to another.Its more easy to....More may be there....
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. An embedded system makes use of embedded hardware (microprocessor) and embedded software to accomplish its purpose. Embedded software is generally comprised of: * Real-time operating system (RTOS) * Drivers (HW peripheral interface) * Application software
Embedded operating systems cannot be replaced with other operating systems. embedded system are designed for dedicated applicationembedded system are tailored to specific application.
ð An embedded system is differ from the general purpose in the view of their purpose. The general purpose computers are the computers that are designed to perform many operations and which can be reconfigured for a new purpose where as an embedded is designed only meant for one purpose.ð An embedded system has a self-contained operating system on a "chip" hence embedded into the system and does not depend on having a hard disk with the operating system on it, whereas in the general purpose computer an operating system need to be present in the hard disk.ð Example for an embedded system is a portable music player; example for general purpose computer is PCs.
Conventional OS aim to give users the ability to run other software that are interactive in nature to perform different tasks. On the other hand, embedded OS only run fixed set of tasks and deliver the expected results in real time.
It is because the basic definition of embedded system is that it involves hardware and software for a single application. The device that is using an operating system may be an embedded system. But the operating system itself is not an embedded system It is because that it is only a software but not the combination of hardware and software.
embedded systems are hardware IT is software if you are a Bookkeeper you may not see a difference an electronic engineer would get in the embedded systems as soon as he could
