Before we can explain what a "task" is in an embedded system it is important to understand that most embedded systems use a single microcontroller or microprocessor. The microcontroller (MCU) can do only one operation at a time but is fast enough to handle thousands of these operations per second (or much more, depending on the MCU). The application developer decomposes the application into a series of tasks (also known as threads or processes).
Each task is given control of system resources by the real-time operating system (or some other scheduler) for a period of time and then yields control to another task. These tasks must share the MCU with all other tasks so it is important that no single task dominates the system. The developer assigns a priority to each task. The scheduler (in the real-time operating system) gives control of the system to the highest priority task that is ready to run, preempting any lower priority task that is currently in control of the system.

What is embedded application architecture?
An Embedded Architecture is a board that is implemented as the embedded system when programmed an embedded architecture is also a target board on which a uProcessor is plugged
Can you use a printed circuit board on an embedded system?
I cannot imagine a modern embedded system that is not built on a printed circuit board.
An embedded operating system resides on what chip?
A ROM chip
Define science and technology?
Technology is (the knowledge) how you perform a task. Science is the knowledge of why it works.
When embedded invented?
The embedded system was invented in the mid 1980s. However, it was not really used in personalized computers and robots until the mid 90s.
Why operating system is not a embedded system?
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.
How embedded systems is used in dishwasher?
Yes an embedded system by definition is a combination of hardware and software,here both are combined together for a specific task .
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.
Define how operating system is a control program?
operating system is a control program as it allow multiple task to performed on same window.

Difference between microcontroller based system and embedded system?
embedded system also include microcontroller.
What is the need of embedded system?
It's a method of putting software into a processor that can neither be accessed by the user or corrupted by outside sources. It's also usually a dedicated system designed to do a specific set of tasks. " The embedded system are used for creating artificial intelligence with technology so that the system designed for a particular task could perform efficiently without human intervention .For quick performance and to avoid human interventions embedded systems are needed . Embedded system is a part of complete device often including hardware and software designed for special purpose. "
What do you means of resister in embedded system?
in embedded system resister means, memory to store the data.
What is embedded internet system?
internet control of embedded devices
Is operating system an embedded system?
An embedded system can include an Operating System to perform support functions for the application software and hardware. Because of the restrictive nature of an embedded system, its operating system will be compact and more efficient and will exclude many of the capabilities necessary in a general operating system. No. 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.
What are the characteristics of an embedded computer system?
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.
