When to use embedded system?
Embedded systems are used to manage a certain operation inside of a device. Embedded systems are often merely made to carry out this task repeatedly, but more advanced ones can take control of whole operating systems.
What software engineering do?
a software engineer is a person who designs and programs system-level software, such as operating systems, database management systems (DBMSs) and embedded systems. The title is often used for programmers in the software industry who create commercial software packages, whether they be system level or application level. "Software engineer," "systems programmer" and "systems engineer" titles are often synonymous.
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.
Do mac operating systems crash often?
Mac operating systems very rarely crash because of the computer's powerful and innovative design. As far as I know, my Mac has never crashed for 4 years and counting.
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".

What is difference between an embedded system and a general purpose computer?
An embedded system has a self-contained operating system on a "chip" thus embedded into the system and does not rely on having a hard disk with the operating system on it. Not to mention that is will be much faster because the access time of the OS on a chip. More specifically... 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. A PC is designed to be a general purpose computing environment. 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.
Would an operating system be an information system or an embedded system?
If you are talking about a P.C (or Mac) operating system, then it would be an information system. An embedded system is something like that in a modern washing machine. It only deals with a pre- set range of parameters, and is often run on specifically designed hardware, with the memory containing the "system" physically attached to the chip.
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
Why is C plus plus not widely chosen for embedded process application?
There is no such term as embedded process application but you probably meant embedded system software. Embedded systems can make use of general purpose compilers, assemblers and debuggers, but these are often used in conjunction with more specific high-level programming tools and modellers, many of which emit C-code or raw assembly.
On what operating systems can Fetchfido games be played?
Fetchfido provide flash games, thus they can be played on any operating system that supports Adobe Flash. Flash normally comes as standard with most internet browsers or most operating systems. The most popular operating systems include Windows, OSX and various Linux Distros, such as Mint and Ubuntu. Flash is even often available on Android and iOS devices.
What is one type of operating system?
The different types of operating system are as follows:-Real-time Operating System: It is a multitasking operating system that aims at executing real-time applications. Real-time operating systems often use specialized scheduling algorithms so that they can achieve a deterministic nature of behavior. The main object of real-time operating systems is their quick and predictable response to events. They either have an event-driven or a time-sharing design. An event-driven system switches between tasks based of their priorities while time-sharing operating systems switch tasks based on clock interrupts.Multi-user and Single-user Operating Systems: The operating systems of this type allow a multiple users to access a computer system concurrently. Time-sharing system can be classified as multi-user systems as they enable a multiple user access to a computer through the sharing of time. Single-user operating systems, as opposed to a multi-user operating system, are usable by a single user at a time. Being able to have multiple accounts on a Windows operating system does not make it a multi-user system. Rather, only the network administrator is the real user. But for a Unix-like operating system, it is possible for two users to login at a time and this capability of the OS makes it a multi-user operating system.Multi-tasking and Single-tasking Operating Systems: When a single program is allowed to run at a time, the system is grouped under a single-tasking system, while in case the operating system allows the execution of multiple tasks at one time, it is classified as a multi-tasking operating system. Multi-tasking can be of two types namely, pre-emptive or co-operative. In pre-emptive multitasking, the operating system slices the CPU time and dedicates one slot to each of the programs. Unix-like operating systems such as Solaris and Linux support pre-emptive multitasking. Cooperative multitasking is achieved by relying on each process to give time to the other processes in a defined manner. MS Windows prior to Windows 95 used to support cooperative multitasking.Distributed Operating System: An operating system that manages a group of independent computers and makes them appear to be a single computer is known as a distributed operating system. The development of networked computers that could be linked and communicate with each other, gave rise to distributed computing. Distributed computations are carried out on more than one machine. When computers in a group work in cooperation, they make a distributed system.Embedded System: The operating systems designed for being used in embedded computer systems are known as embedded operating systems. They are designed to operate on small machines like PDAs with less autonomy. They are able to operate with a limited number of resources. They are very compact and extremely efficient by design. Windows CE, FreeBSD and Minix 3 are some examples of embedded operating systems.
