It is a code for representing 128 English characters as numbers, with each letter assigned a number from 0 to 127. For example, the ASCII code for uppercase M is 77. Most computers use ASCII codes to represent text, which makes it possible to transfer data from one computer to another.

Why would extended ascii be used?

ASCII stands for American Standard Code for Information Interchange. ASCII code allows computers to understand how to represent text. … This is because extended ASCII uses eight bits to represent a character as opposed to seven in standard ASCII (where the 8th bit is used for error checking).

What’s the difference between ascii and extended ascii?

The basic ASCII set uses 7 bits for each character, giving it a total of 128 unique symbols. The extended ASCII character set uses 8 bits, which gives it an additional 128 characters. The extra characters represent characters from foreign languages and special symbols for drawing pictures.
