Hexadecimal ASCII refers to the representation of ASCII (American Standard Code for Information Interchange) characters using hexadecimal (base-16) notation. Each ASCII character is assigned a unique decimal value, which can be converted into a two-digit hexadecimal equivalent. For example, the ASCII character 'A' is represented as 65 in decimal and 41 in hexadecimal. This format is often used in programming and data encoding to compactly represent text data.

Without context, it is difficult to say. I guess you are referring to number bases greater than 10 where letters are used to represent digits above 9; the first digit would be A, the second B and so on. In these cases the letter A is being used to represent 10 times the column value where it is. For example in hexadecimal, the A in 0x6A3 represents 10 x 16 = 160 in decimal (since it is in the sixteens column of the number).
