Understanding Binary Code

[HippySunshine]

Hello,

So I really want to understand binary but having a damn hard time getting my head around the explanations I found online

Anyone want to take a crack at an explanation for little old me?

Thanks

I once created a computer game in binary code in "Basic" on the Spectrum 48k - I was only 9 or 10 years old then - I don't remember much about programming "Basic" or programming in binary these days.

It's a skill which I wish I had kept up.

Thanks for that, but that's gone straight over my head!

Ok so you have an ASCII table
https://www.asciitable.com/

ASCII - American Standard Code for Information Interchange

This is what's used as the template for assigning letters and numbers to Binary.
If you like it's the alphabet of binary.

You see on the left hand side it says "DEC" and the reference for "A" is "65"


If you wanted to say Hello in decimal it would be
72 101 108 108 111

So Hello in Binary is

Example
01001000 01100101 01101100 01101100 01101111

Explanation of
01001000

01001000 represents H (decimal equivalen 72)

You will notice each binary letter is 8 digits

You work it out from right to left
It's stored in BITS - and it goes to the power of 2, so starting right,
1st number=1, 2nd number =2, 3rd number=4, 4th number =8
(1*2=1) (2*2=4) (4*2=8) (8*2=16) (16*2=32) (32*2=64) (64*2=128)

It finishes off like this
128 64 32 16 8 4 2 1

For H
The bits turned on and off are represented by 1's and 0's



For H bits 128, 32, 16, 4, 2 and 1 are all switched off

BITS 64, 8 are turned on

Therefore the Binary translation is now 64+8= 72
