What is Binary Code?

Binary code represents text, computer processor instructions, or any other data using a two-symbol system. The two-symbol system used is often "0" and "1" from the binary number system.

How It Works

Each character is represented by a sequence of 8 bits (a byte). For example, the ASCII value for the letter 'A' is 65, which is represented in binary as 01000001.

Practice Time!

Let's write "HI" in binary.

H -> 01001000

I -> 01001001

So, "HI" becomes "01001000 01001001".
