Yeah , but they like to celebrate it in October . Weirdos . <| sep |> Lick it in case it ' s syrup . <| sep |> You can remove it in settings . <| sep |> It ' s not up to you though . The mods are the ones doing the tagging <| sep |> Base 16 implies that they number system has 16 symbols , just like base 10 implies 10 symbols , 09 . Really , any symbol could do , you can use anything from the alphabet to emojis on Twitch . The important part is that they are designated that they are sequential , aka one symbol is 1 greater than another , which is one greater than another , ect . We just decided to use 09 since we are already familiar with it , but then we need another 6 symbols , so we use the first few letters of the alphabet , since we are already familiar with them . As for why computing often uses base 16 , it is because it is a convenient way to express a byte , which is one of the most basic storage possible in most computers these days . A byte is 8 bits , and each bit is a 1 or a 0 . So it is 8 base 2 characters . This gives us a total of 28 , or 256 different bytes possible , similarly how there are 100 possible numbers you can make with 2 base 10 characters . Base 16 is convenient since 2 base 16 characters can also make up 162 , or 256 different individual letters , but instead of having to read 8 characters , you only need to read 2 .
