ASCII and EBCDIC are character encoding standards. ASCII uses 7 or 8 bits to represent 128 or 256 characters and was designed for small devices and communication. EBCDIC is an 8-bit standard used in mainframe computers and includes characters for punctuation and accented letters not in ASCII. The document provides examples of how letters are represented in binary code under each standard.

1. Difference between ASCII and EBDIC<br />ASCII:<br /> American standard Code for Information Interchange<br />PURPOSE: <br />To be widely used in small peripherals, computer instruments, and various communicating devices.<br />It is a character encoding standard.<br />TYPES:<br />ASCII-7

2. ASCII-8ASCII-7: 7 bit code that can represent 128(27) different characters.<br />Computers using 8 bit byte and 7 ASCII either set 8th bit of each byte as zero or use it as parity bit. ASCII – 8: extended version of ASCII-7<br />8-bit code that can represent 256(28) different characters.

3. Additional bit is added to left of 7th bit of ASCII-7 codes.
