Embedded system consists of two terms one is embedded and other is system. So what is the meaning of both the terms?
- Embedded ? Fix (an object) firmly and deeply in a surrounding mass.
- System ? A set of things works together as parts of a mechanism or an interconnecting network. In Computing – A group of related hardware units or programs or both, especially when dedicated to a single application.
WHAT IS EMBEDDED SYSTEM?
Embedded system is a combination or you can say for better understanding it is a sandwich of software and hardware.
Here software means package of program to perform specific task as per your objective.
As you know program is set of instruction which perform specific task. To do program, we developer use certain type of programming language which is better to use and understand.
To implement application in real time world, system designer uses certain type of hardware which could operate as per your program instruction.
Hardware could do defined operation via movement and rotation. You can say something like human arm. On other hand, it could sense something and give some data like your tongue which taste different cuisine and human brain decide kinds (yummy or tasteless).
As I discussed embedded system is like a sandwich.
But question is; How system designer would design this sandwich having all raw material which is necessary?
Answer is electronic components …
What kind of electronic components? Those are capable of doing all those process ?
