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?

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.
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 .
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.
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. "
