Well, truly specking I don't had much access to the computer before but now I have full access to it as I have owned it. I can work on windows only. I am gonna learn linux and unix also. And about to join programming course also.
Based on what you said you should just start learning how a computer works not just on the hardware level but you need to know how information
is processed.My advice is the first certification you should be working towards is A+ .Then after that start learning networking.
