ASCII vs. EBCDIC: Know the Difference
By Shumaila Saeed || Published on February 28, 2024
ASCII is a 7-bit character encoding standard for text; EBCDIC is an 8-bit character encoding used mainly in IBM mainframe systems.
Key Differences
ASCII, or American Standard Code for Information Interchange, is a widely used character encoding standard for electronic communication, representing text in computers and other devices. EBCDIC, or Extended Binary Coded Decimal Interchange Code, is a character encoding used primarily by IBM mainframe systems, differing in its structure and design from ASCII.

ASCII uses a 7-bit binary code to represent 128 characters, including control characters and printable characters, making it suitable for a wide range of languages and applications. EBCDIC, with its 8-bit binary code, provides 256 character representations, but its design caters more to punch card systems used in early IBM computers.

One key difference is the arrangement and values assigned to characters. In ASCII, characters are logically ordered, making it easier to sort data alphabetically. EBCDIC's character arrangement, in contrast, is less intuitive due to its origin in punch card technology, leading to complexities in data sorting and processing.

ASCII's influence extends beyond just character encoding; it is foundational in the development of modern coding systems and internet standards. EBCDIC remains more specialized, primarily used in legacy systems within IBM mainframes, with limited use in modern computing environments.

Compatibility and interchangeability between ASCII and EBCDIC can be challenging, as converting text between these two requires mapping of character codes, which may not always have direct equivalents. This difference underscores the specific design goals and usage contexts of each encoding system.

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.
