Picture of Learn Binary (The easy way) 01000001 00000001

So a while ago I wanted to learn binary. Binary is the way a computer holds information, the 1's and 0's. I thought it was cool, and that it would be worth learning. It is WELL worth learning and it is very simple to learn.

What I am showing you in this instructable, is how letters work.

Step 1: What binary is

Picture of What binary is

What I am going to show you today in binary is simply just the replacement of letters and numbers, with their binary equivalent. 1 and 0 are just a representation of on and off. 1 = on 0 = off. There are put in sections of "on and off's" also, usually sets of 8, called a byte. The digits are all valued exponentially, the easiest way to explain what that means is to show you, it is in the first picture at the bottom.

This part isn't quite as important as others for the purpose of this instructable.

Step 2: How letters and numbers work

Picture of How letters and numbers work

To make different numbers all you do is add up the 1's. Letters on the other hand, are a bit more complicated. What you need to do, is give all the letters a number value. For example a=1, b=2, and c=3. To signify that something is a letter, and not a number, you put the code 0100 for a capital and 0110 for lower case. So the letter 'A', is the code 01000001, and a lower case 'a' is 01100001. To make a space you put the code 0010000 and to make a period you

put the code 00101110.

The way you turn latin letters in to a binary sequence is
All sequence us 8 digets or 1 & 0s
For example 01110011= s
The first two digets is always 01 for letters
The 3rd number is if the letter is a capital or not 1=lower case 0=upper case
The 4th number is which group there in 0=the letter a to o 1=the letter p to z
The last 4 digits have values 8 4 2 1 (in that order) then you need to find out how many numbers down the alfabet your letter is if its the 6th number then you write 0110 at the end. A=0001 b=0002 ect but when you get to p then you say it is in the group 1 ( digit 4)
And p=0000 q=0001 r=0010 ect
P.s. sorry if it isnt very clear its kinda confusing to explain
Awesome!! But i have some questions... When we get to "K" (11th number in alphabet) what do we write in the last 4 digits?

You can't get k in binary since binary only goes a-f

Binary is the number system that uses a 0 or a 1. Getting a k in this case is just a representation that's been defined (ASCII for reference), so a "k" would be 01001011.

"K" would be 0100 for the first 4 places and 1011 for the last 4 places. The reason for this is due to how the binary to alphabet conversion is defined by ASCII (American Standard Code for Information Interchange).

U been spelling long mate?

There is actually no s it only goes a-f or 1-9

You are confused with hex I think :)

"a-f" or "1-9" is not correct for any number system. "0-9" followed by "a-f" is hexadecimal which I'm guessing is what you're remembering.

01000011= K right?

There is no k only 1-9 and a-f

your so dumb :")

Just so you don't look dumb as well in the future :)

We have a "Be Nice" comment policy.


hey man i don't know where you are getting your information but you are completely wrong with that, an eight digit binary code has all english letters and and can go up to 257.

my bad 255

256 u forgot 00000000

this comment looks like a diss, like he's actually saying "OOOOHHHHHHH"

01000100 01010101 01001101 01000010 01000001 01010011 01010011

if there was no g-z then binary wouldn't be a legitimate language

"a-f" or "1-9" is not correct for any number system. "0-9" followed
by "a-f" is hexadecimal which I'm guessing is what you're remembering.

No, that means C

0100 1011 = K
K is the 11th letter in the alphabet.
0100 means this is a capital letter.
The second 4bit 'pack' represents each letter so the 11th letter is 1011 because if you're reading from the right to the left there is a 1, a 2 and a 8 but no 4.. hope you can understand me :P

So if you have the code 01101111
That only goes from a-o
How do you get all the other letters?

A: 01000001

a: 01100001

B: 01000010

b: 01100010

C: 01000011

c: 01100011

Am I right?

EphraimB9 months ago do you do numbers?

ShiK1 EphraimB2 months ago

You see... a single binary code for example "01100001" (a) has 8 digits. From the left to the right of the code "01100001" will be read as "128 off, 64 on, 32 on, 16 off, 8 off, 4 off, 2 off, 1 on." Using the numbers 128, 64, 32, 16, 8, 4, 2, and 1, you can turn on aha series of digits to add up together the number you want. The number 16 in binary is 00110001 00110110 which is 1 and 6... thus forming 16...

Binary without any code is numerical. The.code ie 0110 changes it into.letters.

I have the same question..

01010100 01101000 01100001 01101110 01101011 00100000 01111001 01101111 01110101 00100000 01110110 01100101 01110010 01111001 00100000 01101101 01110101 01100011 01101000 00101110.

You can also use a substitution cipher to make it more secret like...
