To be computer literate, just means you can use the basic functions of a computer, for example word processing, emailing, using the internet, printing etc. That's my understanding anyway.
Well, literacy and numeracy are both classed as skills, but computer literacy doesn't sound right to me. I'd say I had computing skills/keyboard skills/ICT skills or whichever term best fitted the purpose you required it.
Also think you were rather rude to someone who tried to help you. Maybe your interpersonal skills could do with a bit of attention?!
