So, nobody in the past would have predicted that it would actually be possible, to talk to the person living in another continent at the real time; not only talk but also see each other. It is all like a magic if we see at a surface view of these things. These all developments are not a contribution to an individual or a company, there are numbers of such individuals and companies involved in the process and their series of desires and dreams has led us to the era we are upon. Information technology has developed so much in recent times.
How does it work? How does the cell phone work or that small heartbeat sensing device or that ATM machine or that vending machine or that routing device? Questions like this always used to arise in my mind while I was a kid and I believe everyone had this question on their mind when they were too young to know the real fact. So, the question is how it works or that works or that small beeping device works? The basic idea behind every electrical and electronic device is that there is a small controlling chip called 'Microcontroller' or 'Microprocessor' to which we provide certain instructions to perform the task needed. The instructions are the program that is given to the microprocessor or microcontroller that controls the behavior of the system. The programming simply is the process of telling the microprocessor or microcontroller to do the certain task under certain condition and to do other tasks under another condition. The programming can be done through the various high-level and low-level programs which we will discuss in our further posts. Thus, every embedded device you see, there is the combination of hardware components and programming. This much for today we will discuss more related things in other posts. Thank you.
