i should learn basic binary

even if your into programming there are very few practical applications of it, but if your like me and just like learning shit like this go for it

For binary I was taught that way and then an easier way (if you think of it as an easier way)
This way requires a bit more scratch but it’s pretty helpful.
256 128 64 32 16 8 4 2 1
So you have to think of the above as some sort of yes/no system. If the number is included (and will make it add up to the decimal) then you’ll put a 1 below it, and if not a 0. So if you’re trying to get 234
256 128 64 32 16 8 4 2 1
.........1 1 1 0 1 0 1 0
(formatting is a bit off because they don’t allow tons of spaces. = (but it should be 1:0 2:1 4:0 8:1 16:0 32:1 64:1 128:1)
All of where it’s 1 is a “yes” (if you think of it more as a circuit works t/f h/l y/n on/off) then the number is added, where it’s a 0 the number is ignored, so your final result is 11101010.

yeah thats what they taught us in cisco back in highschool

Sonata: For binary I was taught that way and then an easier way

thats the way I initially learned it, makes alot more sense then all those calculations 

Sonata: For binary I was taught that way and then an easier way…

Yeah I found this to be easier to understand when first learning about decimal <-> binary conversions.

thats some complicated stuff

Nah. It’s quite easy actually. Octa and hexa decimals are a bit worse.

Just an example of practical use: If you have a micro controller with 8 ports and want all of them open, you give the MC the number 11111111(binary), 255(decimal) or FF(hexa decimal). What a lot of people do wrong here is calculating 11111111 to be 2^8=256. Typing this decimal number would give you the value 100000000 in binary, which would close all the ports except the non-existent ninth port.
