Why does ASCII use 7 bits and not 8?

ASCII was originally developed for basic computers and printers. It uses a 7-bit code to represent characters. As more computers began to work with 8-bit groups of data, ASCII was written as 8 bits. So ASCII represents 128 characters (the equivalent of 7 bits) with 8 bits rather than 256.

What is a limitations of 7-bit code ASCII?

What are the advantages of ASCII?

Advantages:
