Most of the popular embedded controllers are for video and sound. An mp3 that plays when a page loads is great if the visitor needs or really wants to hear the automatic sound. A stop or play button can be added as well as how the lloop or file itself plays. A playlist and several more options are available. The video player is still there to automatically play video in the same way, except for the player will become visibale according to the setup. Forward and volume, plus several options are available for the video player. In both of these examples the player will be embedded and the result is the designer has total control over what media the visitor will experience. The major fqctor is what type of system the visitor has will determine whether they hear or see anything at all.
An embedded system can be thought of as a small component in a larger electrical framework. In a computer, for example, each individual component, such as the motherboard, functions as an embedded system within the computer.

Embedded system is a combination of software and hardware system ,in which s/w drives the hardware. The main objective :- (1)less power consumption (2) memory constraint (3) less area requirement
list and explain some important characteristics of a computer?
Special purpose memories are areas that offer storage capability for computer data that has a unique purpose. This is an embedded system within the computer that has its own unique language and design tools available to the user.

An embedded system can be thought of as a small component in a larger electrical framework. In a computer, for example, each individual component, such as the motherboard, functions as an embedded system within the computer.
A computer system which has been specifically designed for a particular function from within a larger computer system is what is called an embedded system.
In a computer system, an embedded component is a integral part of the system's motherboard.A component which was operated by both hardware and software was called embedded component.
An embedded operating system is an operating system for embedded computer systems. These operating systems are designed to be compact, efficient, and reliable, forsaking many functions that non-embedded computer operating systems provide, and which may not be used by the specialized applications they run.

Embedded system is a term used in computer technology. Essentially, it is a computer system with a dedicated function within a larger mechanical or electrical system.
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.
An "embedded" computer is a computer that is part of another device. For instance modern televisions have a computer inside them. This computer is part of the television and is dedicated just to doing what the television needs to work. Another example would be the computer comprising the engine management system of modern cars.Another term often used for an embedded computer is a 'micro controller'. This is because the main purpose of an embedded computer is to control something.All of the following contain an embedded computer:telephonestelevisionscameraswashing machinesmicrowave cookersdishwasherscarsThese systems are mostly used in all type of communication computing, display and any other electronic device that we can think of. Spanning across all aspects of modern life consisting of communication, science, education and entertainment, embedded system are dedicated to specific tasks.A specialized computer system that is part of a larger system or machine. Typically, an embedded system is housed on a single microprocessor board with the programs stored in ROM. Virtually all appliances that have a digital interface -- watches, microwaves, VCRs, cars -- utilize embedded systems. Some embedded systems include an operating system, but many are so specialized that the entire logic can be implemented as a single program.
An embedded system or embedded computer system is a computer system which is designed to perform one or more tasks related to a particular real time application with application specific microcontroller or microprocessor based circuitry embedded in it.They are aimed at providing responses within a set deadline by the manufactured who would have deviced it from customers point of view. In contrast,general purpose computer system is a computer system which is designed to perform one or more tasks related to general purpose applications with a general purpose microprocessor based circuitry either existing as a separate unit(as in desktop) or embedded(as in palmtop,laptop).They are mainly aimed at providing maximum throughput(Throughput refers to measure of system's execution efficiency in instructions per second).A general purpose computer is a non-real time system,in the sense it need not meet deadlines.A general purpose computer is built around various embedded peripherals such as mouse,printer, router,scanner,etc.Real time system refers to a system which responds to any user input with minimum latency.Since PC's are surrounded by embedded peripherals they cannot come under category of embedded systems because of the following reason: They require a external reset by the user when system hangs.whereas in embedded systems an on chip WDT (WatchDogTimer ,also referred to as COP[ComputerOperatingProperly]timer automatically resets the system under such condition.
