What is exact definition for embedded system?

Answer 1

An embedded system is a special purpose system, in which the computer is encapsulated by the device it controls. Unlike a general purpose system an embedded system will only perform some particular tasks. These are actually systems which are developed for performing some predefined tasks. Embedded systems may vary from small hand held devices like PDAs to large devices like robotic arms.
Embedded systems are generally control systems which are a part of another device and they can handle the entire operation of that device. They are generally electronic chips with CPU, memory,I/o ports and are programmable.

Answer 2

An embedded system is designed to perform one or more functions that will make the human job easier than before. Embedded system is the combination of hardware and software components.

Embedded training and learning combine reading, communication, and numeracy development with professional and other skills development. Learners will obtain the competence, confidence, and drive they need to progress, gain certifications, and succeed in life and at work as a result of the abilities they have acquired.

Now you know the embedded systems or embedded training importance in the real world. So you can think about its opportunities in the real world. There are no. of opportunities waiting for you. Register yourself for the embedded training and remember that you should only choose the best institute for the embedded training so that you can learn all the concepts well.

• CETPA is the best training institute for embedded training in Noida.
• CETPA is the most trustworthy institute and has been awarded many times as the best training institute.
• CETPA is an ISO-certified institute.
• CETPA certificates are globally accepted.
• CETPA provides you job oriented training with live lab exposure.
• CETPA has tie-ups with top companies for placement.
• CETPA is the only company which provides an online certificate verification facility.

Answer 3

An embedded system is a system dedicated for a particular real time application,with a factory pre programmed microcontroller or microprocessor in it.The processor (and/or)controller used in embedded system are referred to as embedded processor or embedded controller (which may be ordinary or special purpose micro controller or microprocessor).

Answer 4

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. 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. Generally this would refer to an embedded system with very limited resources * Limited computing power * Limited system memory These are choices made by the system developer, usually for cost reasons.

Answer 5

The term "embedded" refers to how embedded systems always work as a component of a complete device. These tiny computers, which are embedded in other mechanical or electrical systems, are inexpensive and low-power users. They usually consist of a processor, power supply, memory, and communication interfaces.
