Key Differences
ANSI, the American National Standards Institute, is an organization that oversees and approves various standards in multiple fields in the US. ASCII, the American Standard Code for Information Interchange, is a character encoding standard that was one of the original standards endorsed by ANSI.
While ANSI plays a role in many sectors, from industrial practices to IT protocols, ASCII is specifically a 7-bit character code used to represent text in computers. The role of ANSI is broader, whereas ASCII is a particular standard under its vast umbrella.
Over time, ANSI has expanded the original ASCII standard to include additional characters, giving birth to the "ANSI" character set in many software environments. This extension of ASCII by ANSI incorporates characters outside the original 7-bit range.
ANSI's involvement in character encoding doesn't stop at ASCII. It has also approved other character encoding standards that accommodate a wider range of characters. On the other hand, ASCII remains a foundational encoding system on which many other systems are based.
It's essential to recognize the distinction between ANSI as an overseeing body of standards and ASCII as a specific standard for character encoding. While ANSI has touched many areas with its standards, ASCII remains specific to text representation in computing.

ASCII
Persons who, at certain times of the year, have no shadow at noon; - applied to the inhabitants of the torrid zone, who have, twice a year, a vertical sun.
ASCII
The American Standard Code for Information Interchange, a code consisting of a set of 128 7-bit combinations used in digital computers internally, for display purposes, and for exchanging data between computers. It is very widely used, but because of the limited number of characters encoded must be supplemented or replaced by other codes for encoding special symbols or words in languages other than English. Also used attributively; - as, an ASCII file.
ASCII
(computer science) a code for information exchange between computers made by different companies; a string of 7 binary digits represents each character; used in most microcomputers
Common Curiosities
What is the main function of ANSI?
ANSI oversees and approves a variety of standards across multiple sectors in the US.
