From computer architecture to platform, I have put together various contents of IT general.

I learned the knowledge I had while studying the engineer, the experience I had while working in the field, and explained what I had done while trying to develop an app or site separately.

I think you should refer mainly to the following people.
Common people who want to know computer common sense
Students who want to study software
College students who want to start IT majors
Developers who want to understand overall IT technology
Those who have just started to study engineering

If you want to listen to the actual contents easily, it is good to refer to it. I tried to subtract professional terms. I tried to explain it easily.
