What is ASCII?
ASCII is an acronym for American Standard Code for Information Exchange. It is a character encoding standard which was developed in the early days of computers for representing and exchanging arbitrary text-based information.
Computers can only understand numbers. Therefore, we need a way to encode characters to numeric form. ASCII encodes 128 specified characters into 7-bit integers so that they can be represented and exchanged easily.
The ASCII character set contains uppercase and lowercase alphabets A-Za-z, numbers from 0-9, some special characters like {'{}[]@$!'}<>, and some non-printable control characters like newline (\n), backspace (\b), horizontal tab (\t), vertical tab (\v) etc.
The above table lists all the 128 ASCII characters and their equivalent encoding in decimal, hex, octal, and binary form.
ASCII Table
The ASCII table is a collection of all the 128 characters of the ASCII character set.
The ASCII table can be classified into four sections -
Control characters: The characters ranging from 0 to 31 and 127 are device control characters. These characters are unprintable.
Lower and upper case alphabets: The uppercase alphabets (A-Z) range from 65 to 90 in the ASCII table. Lowercase alphabets (a-z) start from 97 and end at 122.
Digits: The digits (0-9) range from 48 to 57 in the ASCII character set.
Special characters: The rest of the characters in the ASCII charset are special characters like !, $, @, {} etc.
