Answer 2

In touch-tone dialing, the digits are sent using musical tones. Each digit is formed by playing two tones simultaneously (one corresponding to the row on the telephone dial, the other corresponding to the column). In rotary dialing, the digits are sent using clicks or electrical pulses. Each digit is formed by counting the number of pulses, with a brief pause between digits.
