What are the necessity of embedded systems?
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.
What are the two most common operating systems used in smartphones?
The most common mobile operating systems (OS) used by modern smartphones include Google's Android, Apple's iOS, Microsoft's Windows Phone, Nokia's Symbian, RIM's BlackBerry OS, and embedded Linux distributions such as Maemo and MeeGo.
What does embedded?
'Embedded' simply means 'placed within', for example,He saw a glistening crystal embedded in the solid rock...meaning...He saw a glistening crystal placed within the solid rock. An embedded system is a computer system designed to perform one or a few dedicated functions[1][2] often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts. By contrast, a general-purpose computer, such as a personal computer (PC), is designed to be flexible and to meet a wide range of end-user needs. Embedded systems control many devices in common use today.[3]Embedded systems are controlled by one or more main processing cores that are typically either microcontrollers or digital signal processors (DSP).[4] The key characteristic, however, is being dedicated to handle a particular task, which may require very powerful processors. For example, air traffic control systems may usefully be viewed as embedded, even though they involve mainframe computers and dedicated regional and national networks between airports and radar sites. (Each radar probably includes one or more embedded systems of its own.)Since the embedded system is dedicated to specific tasks, design engineers can optimize it to reduce the size and cost of the product and increase 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 MP3 players, to large stationary installations like traffic lights, factory controllers, or the systems controlling nuclear power plants. Complexity varies from low, with a single microcontroller chip, to very high with multiple units, peripherals and networks mounted inside a large chassis or enclosure.In general, "embedded system" is not a strictly definable term, as most systems have some element of extensibility or programmability. For example, handheld computers share some elements with embedded systems such as the operating systems and microprocessors which power them, but they allow different applications to be loaded and peripherals to be connected. Moreover, even systems which don't expose programmability as a primary feature generally need to support software updates. On a continuum from "general purpose" to "embedded", large application systems will have subcomponents at most points even if the system as a whole is "designed to perform one or a few dedicated functions", and is thus appropriate to call "embedded".

Disadvantages of embedded Operating system?
Embedded operating systemAn embedded operating system is an operating system for embedded computer systems. These operating systems are designed to be very compact and efficient, forsaking many functions that non-embedded computer operating systems provide, and which may not be used by the specialized applications they run. They are frequently also real-time operating systems.Examples of embedded operating systems could include the software used in Automated Teller Machines, Cash Registers, CCTV systems, jukeboxes, etc.Features of Embedded Operating System1-Embedded systems are designed to do some specific task, rather than be a general-purpose computer for multiple tasks. Some also have real-time performance constraints that must be met, for reasons such as safety and usability; others may have low or no performance requirements, allowing the system hardware to be simplified to reduce costs.2-Embedded systems are not always standalone devices. Many embedded systems consist of small, computerized parts within a larger device that serves a more general purpose. For example, the Gibson Robot Guitar features an embedded system for tuning the strings, but the overall purpose of the Robot Guitar is, of course, to play music similarly, an embedded system in an automobile provides a specific function as a subsystem of the car itself.3-The program instructions written for embedded systems are referred to as firmware, and are stored in read-only memory or Flash memory chips. They run with limited computer hardware resources: little memory, small or non-existent keyboard and/or screen.Common featuresThe following table provides an overview of the features common to HP thin clients based on operating system using the following legend3. Feature is fully functional and operates the same as the desktop environment.2. Feature is partially functional and does not operate the same as the desktop environment.1. Feature is barely functional and requires a highly skilled administrator to enable it.
What is the difference between information system and embedded system?
Information systems:- Information System include databases that include useful "information". Information Systems is the discipline concerned with the development, use, application and influence of information systems. An information system, following a definition of Langefors, is a technologically implemented medium for recording, storing, and disseminating linguistic expressions, as well as for drawing conclusions from such expressions. The technology used for implementing information systems by no means has to be computer technology. A notebook in which one lists certain items of interest is, according to that definition, an information system. Likewise, there are computer applications that do not comply with this definition of information systems. Embedded systems are an example.Embedded Systems:-Embedded systems include small computers that make things work, such as the computer in your radio, television or the computer that controls your vehicle engine. An embedded system is a computer systems that is part of a larger system.Examples: * Washing machine * Car engine control * Mobile phone ES Characteristics* Often mass products * 98% of the processors are in ES * Sometimes very specialized systems * No or minimal user interface * Resource constraints * Must usually fulfill strict timing * Usually runs forever (no reboot) For further reading refer to this- http://en.wikipedia.org/wiki/Embedded_Systems
What do organs form according to their common or shared functions?
When organs are viewed according to their shared functions they form organ systems. Organ Systems are formed from Organs, and from Tissues, which ultimately are formed from living units called cells. These organ systems usually develop as an adaptation or natural selection calls for some sort of function, and continues to develop with the evolutionary timeline.
How do you write on methodology?
Methodology is the science of the study of methods, (it is a common misuse to use methodology as "posh method"), just as Biology is the science of the study of living things. How do you write about a science? You could describe its origins, major developments and important conclusions.
