Let's say that we have a string of 25 numbers, containing a telephone number, but we don't know exactly where the telephone number begins or ends. If we move a "frame" the size of a phone number up and down this string of numbers we could reach a wide variety of people and places.

If we add a number into the middle of this string, or delete a number or two from the middle, and we try to use the remaining numbers within the same frame, we will reach someone entirely different. The effect of these additions and deletions is called a "frameshift error".
