The Tape
Now let's look at the machine you just watched.
It has a tape — a row of boxes that hold symbols.

Each box holds exactly ONE symbol:
- 0 or 1 — binary digits
- _ — blank (empty)
That photo on your phone? 10 million boxes like this.
Each one just a 0 or 1. The computer doesn't "see" the photo — it just reads symbols.
