Hi Glenn,

Here's a cool video to explain the binary number system in a quick way.

To get a deep understanding of the binary number system and computer science in general search for the course CS50 on YouTube, highly recommended!!!

Also, the binary number system uses the number 2 as its base number.

thanks this really helped


I'm not sure the binary number systems base number is 2. It's made up of 1's and 0's, 1 being the base number. Wikipedia is always a good source for more info if interested: https://en.wikipedia.org/wiki/Binary_code

Hi Melanie,

"A binary code represents text or computer processor instructions using the binary number system's two binary digits, 0 and 1" - https://en.wikipedia.org/wiki/Binary_code

1's and 0's are 2 digits. :)

Hi Michael,

Haha, just been diving deeper into this to better understand. Yes I was totally wrong and now myself understand what and why the base number is 2.

Thanks for your feedback :)
