How Does a Computer Translate Letters into Numbers?

A computer turns letters into numbers by using something like a special codebook that matches each letter to a unique number.

Imagine you have a toy keyboard with buttons labeled from A to Z, and every time you press a button, it shows a number on the screen instead of the letter. That’s what happens inside a computer, it has its own secret code that changes letters into numbers so it can understand and work with them.

Think of it like a letter-to-number chart. For example:

• A might be 1
• B might be 2
• C might be 3

And so on, all the way to Z being 26.

When you type a letter on your keyboard, the computer checks its codebook and finds the matching number. It uses these numbers to do things like write messages or solve problems.

Computers are really good at working with numbers, but not so much with letters. By turning letters into numbers using this secret code, computers can understand what you're typing, just like how you use a picture book to learn new words!
