Once upon a time, to start your Toyota Camry, you placed a key in the ignition and turned until the electrical connection was made and engine started. To accelerate, you pressed the gas pedal, which pulled a cable attached to a mechanical throttle. Assuming the shift had been manually placed into gear - the car moved. Today, electronics and computers have replaced many of the mechanical parts that once made cars move. To start many cars or place them in gear, buttons are pushed. To accelerate, the gas pedal is connected not to a cable, but to a computer - via electronic circuitry.
