Embed means hidden, Similar word: Small Glass planes are embedded over the compound walls.
But coming to electronics, this is a electronic system which is hidden inside a device ,whose identity is not shown to the outside world,and involve in a particular single application. May be from remote controller to spaceship.
Everywhere we see embedded, your scroll mouse is a embedded device. Very good example of embedded system is our own body organs, Heart is a embedded system.Kidney is one more. Which all has an hardware as muscles and software to do the job intelligently. Lungs. etc involved in a particular job. Which has both software and hardware(muscles), built by God.
Embedded systems are electronic devices that incorporate microprocessors with in their implementations. The main purposes of the microprocessors are to simplify the system design and provide flexibility.
Having a microprocessor in the device helps in removing the bugs, making modifications, or adding new features are only matter of rewriting the software that controls the device. Or in other words embedded computer systems are electronic systems that include a microcomputer to perform a specific dedicated application.
Embedded systems are self-contained programs that are embedded within a piece of hardware. Usually embedded systems are set to a specific task that cannot be altered without physically manipulating the circuitry.
They use specific programming languages and software to develop embedded systems and manipulate the equipment. Embedded systems technologies are usually fairly expensive due to the necessary development time and built in efficiency, but they are also highly valued in specific industries.
- 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 reason such as safety and usability; others may have low or no performance requirements, allowing the system hardware to be simplified to reduce costs.
- Embedded Systems are not always separate devices. Most often they are physically built-in to the devices they control.
- The software written for embedded systems is often called firmware, and is stored in read-only memory or Flash memory chips rather than a disk drive. It often runs with limited computer hardware resources: small or no keyboard, screen, and little memory.
