With special guest, Mick H. Computers are used throughout the world all the time. Computers are in cars, calculators, televisions โ youโre even using one right now. Humans use computers to take information โ things like pictures, words, numbers, and sound, and turn it into electricity. The information is changed into a pattern of electrical pulses, a bunch of electricity โonsโ and โoffs.โ The computers are designed so that they can tell the difference between pieces of information by the different patterns of โonsโ and โoffs.โ Computers change the information you give them, turn it into electrical pulses, make changes to it, and give it back to you in a form you can understand in a matter of thousandths of seconds. Itโs not the computers, itโs the electricity that makes computers so fast.
