Conversion of ASCII code to 16 binary (table)

The so-called ASCII and 16 binary are just conceptual things that are all binary in the computer

The conversion should be the output of the conversion, the same number, in the computer memory is the same, but the output is not the same
ASCII is the encoding of characters, almost the encoding of characters on the keyboard. The following is an ASCII and 16-binary table:

With regard to this table, the key-value characters on the keyboard are stored in the binary memory of the computer, for convenience, converted into 16 binary representations.
Therefore, 45 of the ASCII representation is 4 of the ASCII representation and 5 of the ASCII representation of the link up.
Each ASCII character is converted to a 16 binary that is a two-bit 16-digit number, and similarly, converting the 16 binary to ASCII is two-bit converted into an ASCII character and then joined together.
