[MOVED] How to learn electronic products?

If I were a person who know nothing about electronic products, now I want to learn something about electronic product knowledge, for example, computer, mobile phone, electronic watches, tablet, and camera. So what should I go to study at first? Could you recommend some useful books or all anything else?

it depend what do you mean exactly by "something"

rather than books, watch electronic basics tutorial in youtube.. they show with example and u can understand clearly..

So I must choose what electronic product I want to learn at first.

I really feel your pain.
I am a mechanical guy and I seriously feel I should have done electronics engineering since I was naturally good at mechanics. I have always wanted to build new and outstanding things and the only thing that has kept me from achieving success is the sound knowledge of electronics. I am so dearly dependent on an electronics engineer.
If you want to learn electronics then look at how electronic engineers are made in college. They are taught different electronic components (like Diode, transistors, mosfets, etc etc) , they are taught the concept behind these electronic components and they are taught application of these components. Its a long process of turning into an electronics engineer from a junior college freshman. If you go to youtube, then you will learn
something but that won`t be a sound foundation and right track since you don`t know what to learn and it won`t help you a lot. Its easier to drift away into the world of technology today and hence you need to precisely direct your energy and time if you want to get something out of your
efforts.
My straight to the point suggestion will be --- Download the syllabus of a good electronics engineering college. Read through the syllabus carefully. Start your study according to the syllabus. Give it a lot of time and dedication and within 2 years you will be close to becoming an electronics guy (not an engineer yet). You also need to test your creativity as you learn by doing small easy electronic projects and later a bit complex ones. Unfortunately the human brain does not learn for a long time only by watching, but it understands very well after doing experiments yourself and only then you will be able to apply the concept in reality some day.

What you are asking is a tough thing if you do not have the desire to achieve it. Your desire and interest in the subject will determine if you will achieve what you want.

My major is foreign trade of English,and know nothing about electronic products.Now I think learn electronic products is so difficult and hard for me.But I would like to try my best.
