What is ASCII values?and what are they?

ASCII stands for American Standard Code for Information Interchange.is a character encoding standard for electronic communication. ASCII codes represent text in computers, telecommunications equipment, and other devices.UNIX and DOS-based operating systems use ASCII for text files. Windows NT and 2000 uses a newer code, Unicode. IBM's S/390 systems use a proprietary 8-bit code called EBCDIC. Conversion programs allow different operating systems to change a file from one code to another.ASCII was developed by the American National Standards Institute (ANSI).
