Here’s one possible set of steps we could code:

1. Break the word into individual letters.
2. For each letter, look up the ASCII number value mapped to the letter.
3. For each ASCII number value, convert to a binary number.
4. For each binary number, save the binary number value.

## How do I understand binary code?

How binary code works. Binary code works by representing content (letters, symbols, colors) in a form that computers can understand. This is done by breaking the content down into a numeric system of two digits 0 and 1. To accomplish this, computers use electrical impulses switching OFF and ON to represent these two digit numbers.

What is binary, and why do computers use it?

Binary is a two-digit (Base-2) numerical system, which computers use to store data and compute functions. The reason computers use the binary system is because digital switches inside the computer can only be set to either on or off, which are represented by a 1 or 0.

What is the history of binary code?

The modern binary number system, the basis for binary code, was invented by Gottfried Leibniz in 1689 and appears in his article Explication de l’Arithmétique Binaire. The full title is translated into English as the “Explanation of the binary arithmetic”, which uses only the characters 1 and 0,…
