Fuck off bud , happy Thanksgiving , read a history book and visit a camp in Europe to watch their documentary sometime . There are hundreds of photos and films , don ' t act so naive <| sep |> Nothing worked until i turned 21 , then i just drank heavily for the next 5 years . That helped the depression . Meeting the woman I ' m engaged to was what ultimately cured everything . <| sep |> Ok great ! ! Thanks man ! Will definitely be checking it Asus . <| sep |> Not a big computer guy here but the A to F is most likely because they need a character to fill the spot and 10 would be 1 and 0 so A would be a logical ASCII character to use next . They could have used punctuation or other characters but the alphabet like numbers is structured . They went to F because that is 16 place holders . This would be two bytes . I remember Hex is easy to convert to binary which is what computers need . So basically they use hex because it ' s a logical choice for computers at the machine level . Am I close ? Anyone else ? Edit Ah I googled it . 0 in hex is 0000 in binary . F in hex is 1111 in binary . So for a byte that is all possible combinations !
