Think about it, this guy said one day "I'm going to put these 2 metals together and power it with electricity and it will store photos". Don't you think that's strange. 2 pieces of metal store photos. It's like saying I'm going to put this rock and gum to store songs. It seems strange but when a computer was made to put metals together so words would pop up on a screen is to. Maybe it's just me but can you explain to me something about computers. I don't want to know about "memory is stored in a data bass". I want to know how can metal or plastic make a memory card. Can anyone explain that.
