3. Introduction to the digital electronics
What is “Electronics”?
“Electronics means study of flow of electrons in electrical circuits.”
The word Electronics comes from electron mechanics which means learning the way how an electron behaves under different conditions of externally applied fields.

4. Introduction to the digital electronics
The Institution of Radio Engineers has given a definition of electronics as "that field of science and engineering, which deals with electron devices and their utilization."

5. Introduction to the digital electronics
Now, let’s first learn what is meant by the word “digital”.

6. What is digital? a communication channel or method?
A convenience enabler? 
1s & 0s? 
The inverse of analog?
Bits versus atoms?
Something we can no longer live without?

7. What is digital?
I am often asked ‘what is digital’? … ‘is it just our website, or broader than that?’ … ‘what exactly do you mean?’
So, I asked around to find out the word-on-the-street around ‘digital’.  I was impressed with how many different, nuanced, and insightful answers I was given on the definition — I had to put it all together into a video in order to capture the rich and diverse viewpoints.  In the video, you can learn what others think ‘digital’ is, as well as how we define it.

8. What is digital?
Watch the video to see how our colleagues and members of the public describe it; listen to hear if your definition is included; and let me know whether you’d add a different perspective.

10. What is digital?
Formally, Digital describes electronic technology that generates, stores, and processes data in terms of two states: positive and non-positive. Positive is expressed or represented by the number 1 and non-positive by the number 0. Thus, data transmitted or stored with digital technology is expressed as a string of 0's and 1's. Each of these state digits is referred to as a bit (and a string of bits that a computer can address individually as a group is a byte).

11. What is digital electronics?
Let’s now define “Digital Electronics”.
“Digital electronics, or digital (electronic) circuits, represent signals by discrete bands of analog levels, rather than by a continuous range.”
So, now let’s find out what is meant by “analog”?

12. What is Analog?
Analog means continuous in nature, such my voice, or any of the bioelectric signals generated by a living things.
Digital means, as defined earlier, discrete, e.g., temperature recorded everyday in the morning at 8:00 a.m.
