Maybe it's an off-topic question but I really had no idea where to ask this question

As a 17 years old boy, who is interested in learning about computer and devices I figured out, I really need and I really want to know what actually electronic is ,and how electronic devices work.

So as someone who actually knows nothing about basics, how can I start learning it ? What sources should I use ? Is it really needed to be studying at university ??

Need to add we haven't been taught anything about electronic at school in my country and I haven't found any online courses or classes for beginners

****Edit******

I said I haven't found any online course about electronic, I meant in my own language

And need to add I have done such thing before in school and home like creating a radio or alarm or ..... but I meant no one never told us how actually they work . They haven't ever told what is the essence of electronic stuffs for example why should be that resistor be before that transistor and ....

I hope you have figured out what I mean Thanks to all answers

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise. If this question can be reworded to fit the rules in the help center, please edit the question.

    \$\begingroup\$ When I was much younger than you (Internet did not exist yet), I went to the local library and read everything related to electronics. I got some parts from discarded radios etc. Experimented with some simple circuits. Today all this is so much easier with all the info on the Internet so read everything that interests you and take it from there. Instead of asking where to find this knowledge, go and seek it yourself ! \$\endgroup\$ – Bimpelrekkie Jul 19 '16 at 21:20

The best way to learn electronics is to get a few parts and start tinkering, usually at age 12 or earlier. You are starting late, but it's still possible. Get some transistors, resistors, and capacitors and start building simple circuits.

Try to fix stuff. Like, a lot of stuff. Be careful with mains-powered equipment, though.

Fixing a broken device has the advantage that you know exactly when your reasoning was right. Also, you are probably led along many false routes during the process, and once you found the cause, in hindsight, it appears all too easy. This makes you keep a modest attitude towards building your own circuits in the best possible way and you learn to question your designs.

You can never learn enough from fixing stuff. Here's an excerpt from Jim Williams' article "The Importance of Fixing", as published in the book ART & SCIENCE OF ANALOG CIRCUIT DESIGN:

Oh how I like the part about fooling yourself...
