What is the Application of ASCII?

This is a language used in computers.this is low level language.it is also called machine level language

sorry but your a bit confused
machine language is the number equvilant of assembly (add jmp ret or clr)

ascii is the format that came about with 8 bit teletype 1" paper tape
the first one was baudout 5 bit tape which allows 32 different letters
so in a language like English with 26 letters if you want to put a number in a message it must be in this format "twenty nine" a-z is 26 32- 26 is 6 so the '0 to 9' wont fit baudot code introduced one of the codes for a shift Figures to go back Letters so now you can do 0-9 and sixteen more codes "$%#()...,,,"

ascii used a fill 1" wide paper tape that has 8 holes for the unbelievable shift to 256 characters A..Z 0..9 leaves us 220 so hey add a..z %$&... keep the old six ACK NAK BEL dont need letters figures anymore

this entire page is ascii up on your browser there's a button that says view page source you can see the ascii

it has codes between <> that is called HTML telling your computer " big little red blue picturehere"

next came unicode which is 16bit letters adds Greek Spanish Russian
and maybe 40,000 Chinese characters (simplified)
