ASCII 7-Bits Vs 8-Bits

There are two versions of ASCII 7-bit and 8-bit, the first 7-bit version of ASCII contains 128 characters, which means all the printable and non-printable characters start from 0 and end with 127 decimal numbers.

We generally use ASCII characters between 32 decimal to 127 decimal numbers. (all upper case and lower case alphabets(a to z or a to z), digits(0 to 9), special characters, non-printable and control characters(CTRL, Shift, and ALT).

We all know there are 2 bits 0 and 1 so 7 bits meaning 2^7 or 2*2*2*2*2*2*2 is equal to 128, we also know that ASCII characters value is start from 0 to a total of 127 characters in 7-bit ASCII.

Ascii was extended to 8 bits which means 2^8 or 2*2*2*2*2*2*2*2 is equalled to 256, so the total characters in an extended ASCII are 255. So basically we can say that after 127(which means starting from 128) to 255 all the characters are coming in under 8-bit ASCII or extended ASCII. Learn more about ANSI.
