1. Read the text and complete the table.           The Computer

   Believed to have been invented in some time around World War II, by Alan Turing or by Konrad Zuse, depending on whether you ask Alan Turing or Konrad Zuse. Actually invented at some time around 1833. Charles Babbage was a man who hated errors. Mistakes and mathematical untidiness upset him so much he decided to build a ridiculously complex machine just to stop idiots from not doing maths right. In 1822, Babbage proposed the idea of building a mechanical calculator to tabulate polynomial functions. The British government, or those officials who didn't fall asleep while Babbage explained the idea, gave him a huge bag of money with a pound sign painted on it and sent him to work on it. 10 years later they finally figured out Babbage was never going to finish the machine because he had such an angry temper that he quarrelled with everyone who tried to help him. By that time Charles had already moved on to bigger things. He looked at his strange polynomial functions tabulator and thought, «You know what's cooler than polynomial functions? A machine you could program to do all different kinds of maths!» He asked the British Association for the Advancement of Science for funds and was surely denied. The last version of his machine-read programmes and data from punch cards and had a memory capable of storing 1,000 numbers with 50 decimal digits each, which roughly translated to 20.7 Kb. Only a partial model was finished, when Babbage died in 1878 while still trying to perfect the design.
