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 is the operating system used by vending machines?
Many modern vending machines use embedded operating systems tailored for real-time performance and energy efficiency, with Linux being a popular choice due to its flexibility and open-source nature. Some may also run on specialized operating systems developed specifically for vending applications. Additionally, certain machines might use proprietary software designed by the manufacturer. Overall, the choice of operating system often depends on the machine's features and connectivity capabilities.
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.
Which type of operating system is used to control large equipment and to regulate factory operations?
The type of operating system used to control large equipment and regulate factory operations is known as a Real-Time Operating System (RTOS). RTOS is designed to process data as it comes in, typically without any buffering delays, ensuring timely and deterministic responses crucial for industrial automation and control systems. These systems are often embedded in machinery and are essential for tasks requiring precise timing and reliability.
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.
What does embedded mean?
'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.

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".

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.
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
Difference between general purpose and dedicated operating system?
A general-purpose operating system is designed to handle a wide variety of tasks and applications, making it versatile and suitable for general computing needs, such as Windows, macOS, and Linux. In contrast, a dedicated operating system is tailored for specific tasks or systems, often optimized for performance and efficiency in specialized environments, like embedded systems or real-time applications. Examples of dedicated operating systems include those used in industrial machines, medical devices, or consumer electronics. The key difference lies in their adaptability and focus: general-purpose OS can run multiple applications, while dedicated OS serves a singular, specific function.
