Computers are pretty easy if you're just talking about building your own. It's basically like lego. Slot it in the right slot, hook up some wires, and you're done.
All i know about scripting is that you have to study a lot trough essay and error, it is a very selfish learning, you must be something like a worm XD i mean someday you will be a butterfly and fly trough computing knowledges and all of that stuff, but first you have to spend a lot of time learning, this is, searching, trying, mistaking, correcting, repeat.
I’m currently working on a masters in computer science at Georgia tech.. believe it or not, I’ve learned the majority of skills from googling how to do it.
For example look up a language you’d like to learn (I think Python is the easiest to start with) and then search for “Python (or other language) tutorial for beginners”. You can even search for the specific type of program you want to build such as “build a game in Python” or “make a simple website using Python”
if you are a beginner I suggest you to learn an easy programming language like HTML just to let you know what is scripting
then try JavaScript & Java then you can learn C, C++ & C#
