A photo is converted into a pattern of 1's and 0's which are sent from one phone to another by electric pulses. That pattern tells the phone receiving the photo how to recreate the photo by turning on and off tiny lights called pixels. Pixels make up the screens of all our devices.
Using Morse code, words from messages are translated to a pattern of dots and dashes representing letters and numbers. These patterns of dots and dashes are sent over long distances as pulses of electricity. On the receiving end, the dots and dashes have to be translated back into words so the message can be decoded.
Both CDs and phones use patterns of 1's and 0's to play music. However, CDs actually store music as a pattern of holes (1s) and no holes (0s) on the disc. A CD player reads these patterns and converts them back into sound. Phones are more high-tech and store music as patterns of 1's and 0's on microchips.
