Detailed explanation-1: -One byte character sets can contain 256 characters. The current standard, though, is Unicode which uses two bytes to represent all characters in all writing systems in the world in a single set. The original ASCII was a 7 bit character set (128 possible characters) with no accented letters.
Detailed explanation-2: -Computers work in binary . As a result, all characters, whether they are letters, punctuation or digits are stored as binary numbers. All of the characters that a computer can use are called a character set .
Detailed explanation-3: -A character set is an encoding system to let computers know how to recognize Character, including letters, numbers, punctuation marks, and whitespace. In earlier times, countries developed their own character sets due to their different languages used, such as Kanji JIS codes (e.g. Shift-JIS, EUC-JP, etc.)
