Binary Code

Hello. My name is 1-14-15-14-25-13-15-21-19 and I’m going to teach you about binary code. Binary code is used for sending messages and signals to a computer to tell it to do stuff. They are on CDs to tell a computer to do things. I’m going to teach you how to write numbers in binary code now. So you have a row of 8 numbers. The one furthest to the right is #1. Then the numbers double, the further the numbers go to the left. The number to the left is 2, then 4, 8, 16, 32, etc.

Example: 128 64 32 16 8 4 2 1

Got it so far? Good. The ONLY numbers used to write binary code and 0 and 1. The numbers 0 and 1 are used to represent on and off. For example, number one would be 00000001 because the number 1 (which is furthest to the right) is “on” but the 2 to the left of it is “off”, so is 4, 8, etc. The number 2 would be 00000010 because this time, 1 is off, but 2 is on. 4, 8, etc. are off. The number 3 would be 00000011 because the 2 and 1 that are on sum up to 3.

Here are more examples:

4 = 00000100

5 = 00000101

6 = 00000110

10 = 00001010

50 = 00110010

I think you have an idea of what the numbers are. The alphabet would be like this. A = 01000001. So capital A is the number 1 in binary code WITH a 1 in the SECOND digit. B would be 2 in binary code (00000010) PLUS a 1 in the SECOND digit, so it would be 01000010… All the way to the letter Z = 26 (00011010) PLUS a 1 in the second digit making the letter Z 01011010.

Lowercase letters are the same except it has an extra 1 in the 3^rd digit making A = (01100001) and Z = (01111010).

Now you know how to write numbers and letters in binary code! Yay! 😀

Here’s a fun fact: Binary code was used even in 300 BCE!
