What is ASCII code?

ASCII code as you know its full form
this is code used for information interchange.
like we talk in english our computers talk in ASCII language this is their primary language.
Every input you give to your computer is first converted in ASCII codes after that it goes for processing.
Every english character has its unique ASCII code.

you know the full form so without including it let me give you more details.

ASCII is a character encoding based on the English apphabet. ascii codes represent text in computers, communications equipment and other devices that work with text. most modern character encodings - which support many more characters than did the original - have historical basis in ascii.

historically ascii developed from telegraphic codes and its first commecial use was as a seven-bit teleprinter code promoted by bell data service.

hello friend I can explain the facts of ASCII.ASCII, pronounced "ask-ee" is the acronym for American Standard Code for Information Interchange. It's a set of characters which, unlike the characters in word processing documents, allow no special formatting like different fonts, bold, underlined or italic text. All the characters used in email messages are ASCII characters and so are all the characters used in HTML documents. (Web browsers read the ASCII characters between angle brackets, "<" and ">", to interpret how to format and display HTML documents.)

An "ASCII file" is a data or text file that contains only characters coded from the standard ASCII character set. Characters 0 through 127 comprise the Standard ASCII Set and characters 128 to 255 are considered to be in the Extended ASCII Set. These codes, however, may not be the same in all computers and files containing these characters may not display or convert properly by another ASCII program.

Knowing something about ASCII can be helpful. ASCII files can be used as a common denominator for data conversions. For example, if program A can't convert its data to the format of program B, but both programs can input and output ASCII files, the conversion may be possible.

ASCII characters are the ones used to send and receive email. If you're familiar with email, you already know that formatting like italic type and underlines are not possible. Email transmissions are limited to ASCII characters and because of that, graphics files and documents with non-ASCII characters created in word processors, spreadsheet or database programs must be "ASCII-fied" and sent as email file attachments. When the files reach their destination they are "deASCII-fied" (i.e. decoded) and therefore, reconstructed to restore them for use. Dod that solve your query or you want to know anything else? If you want to know anything else then ask me.
