Tim berners Lee is the man who was a computer scientist and created the world wide web known today as the internet.This was a great discovery as without it there would be no social media or games and many other things so it is easier to find out things instead of looking inside a massive encyclopaedia. The four generations of computers and technology was a big thing as many of the old items adapted into more modern useful things. At first the ENIAC was built a calculating machine which consumed large amounts of electric power and it took 3 years to be built. Then later on the very simple mouse was made as shown below later it turned into a more modern shape and into a different colour. The first laptop was finished on the 1st of January 1981 just a year after the more modern mouse was created. A motherboard is what links everything in the system up to each other it also is the hub for the devices connected to the computer, this is very important as it allows them to communicate to each other. Alan Turing was a extremely clever mathematician and logician who often was called the father of modern computing and helped crack the codes in WW2, Winston Churchill stated that he cut down the war by 2 years with his smartness.
