Information technology career

I am trying to understand iphoneography but it seems too hard for me. Actually these are my brother’s words, who is very agitated because, although he explains everything to me, I keep asking him the same questions more than a couple of times. The problem that I have is that I am far from understanding technology, especially the new one. My brother should me more understanding with me, because I bet he is not capable of learning and understanding a poem.
