What I Want To Learn about Computers

I used to have my own internet on my desk. However, I lost online suddenly like Ikaros because of the rise of ADSL(I used dial up at that time). Therefore, I use that computer for only TV monitor. Now I use one computer at home sharing with my family, but I cannot always use it because of my three young siblings. Anyway, let's get to the point.

What I want to learn about computers is skills that will be neccessary to do something in daily life and on business. For example, when I want to make CG poster, I will need some skills. Also, if I want to edit a video that I record, I will need some skills. Then, I want to learn PC's language if I can to know the computer deeply. I know it's complicated and makes me confused.

I wrote many, but now I think all things I wrote are high level. So I want to finish to learn Micro soft office first. And, After that, I would touch them if I could.

Probably, the most thing I want to learn is just about computer. History, how they work, structure of hard drive, or how to make the computer...
