  24. <p> Vacumm tubes represent binary code in the flow of electricity. It was either on o off depicting 1 or 0. Vacuum tube computers stored data on large magnetic drums and the vacuum tubes performed the calculations. Only one problem could be calculated at the time with these early computers.</p>

  40. <p> Like the vacuum tube, the transistor is eventually a switch contrlling the flow of electricity, but much smaller and more reliable thatn the vacuum tube. Many more transistors could be placed in a computer in a fraction of the space and cost previously required making computers more affordable and powerful.</p>
