Have you ever heard of Alan Turing? Tim Burners-Lee, perhaps?
Maybe you haven't, so I shall tell you.
Alan Turing was a massive help during the second world war. He invented a fabulous machine that was able to read symbols in codes, and convert them to different symbols. This came in handy when German codes were being transmitted to soldiers, because this machine was able to interpret them, and was a huge contribution to the winning of the second world war.
