The Invention of Code
You probably know that code is the language of computers. Code is behind every letter and color you see on this screen. But did you know that the first computer code was invented more than 100 years before modern computers were even invented, or that early forms of computer code involved punching holes in patterns on paper cards? Well, get ready. Today, we’re clicking the Back button to explore what code is and where it came from.

Olden Days Coding
Meet Ada Lovelace
She’s considered to be the first author of a computer program, even though she lived more than 100 years before the invention of the modern computer!
The Coder Who Started as a “Human Computer”
In the early days of the space agency NASA, “computers” were people—talented mathematicians who could complete the complex calculations required to launch rockets into space—and many of them were Black women. They included Dorothy Vaughan, who became one of NASA’s first Black supervisors and one of its first computer programming experts. Read her story in this short article.
Get to Know Binary Code
Binary code, which is code made up entirely of 0’s and 1’s, may be the most basic form of code there is—and it’s part of every modern computer and electronic device (including the one you’re using now). But how does it actually work? Find out in this video from TED-Ed.
Make Your Own Punchcard
