What is the limitation of ASCII code?
Basic ASCII does not have enough bits to deal with languages with large character sets.
How does the ASCII code works?
ASCII is an abbreviation for American Standard Code for Information Interchange. The ASCII code, which is used worldwide, is used to create computer coding languages so computers can interact with people.
Does ASCII contain codes of all the languages in use?
No, ASCII does not contain codes for all languages in use. ASCII (American Standard Code for Information Interchange) is limited to 128 characters, primarily covering English letters, digits, and basic punctuation. This limitation makes it inadequate for representing characters from other languages, such as accented letters or non-Latin scripts. For broader language support, encodings like UTF-8 or Unicode are used, which can represent a vast array of characters from multiple languages.
What is the difference between ASCII and Unicode?
ASCII is a set of digital codes widely used as a standard fromat in the transfer of text. Unicode is an international encoding standard for used with different languages and scripts

What is the purpose of the ascii and extended ascii code?
The ASCII code 128 unique character ( 2 power 7 ). This was enough to represent all the (American and Britain English) characters in the keyboard. Here characters includes Alphabets, numbers, speical characters, symbols and Shift,ctrl,alt, tab (Non-Printable characters). Days rolled on. Other than American and British English, some other foreign languages occupied the space in the computer world. For ex, Korean, Japanesh. These languages extensively used more characters and symbols. Inorder to accompany all those letters/characters, the American Standard Institute enchanced the above ASCII code with one more bit. ie 2 power 8. So its now support 256 Unique characters. This is sufficient to represent all the characters in the all the countries languages. So this broadened ASCII is called Extended-Ascii. Regards, Rajan. P. Anna University.
What are the advantages of unicode?
Unicode is intended to account for as many languages and symbols as possible while ASCII only covers a small subset. (English and some European languages).
This coding system is designed to support international languages like Chinese and Japanese?
unicode or ansic
How many types of ASCII Code explain it?
There are primarily two types of ASCII code: standard ASCII and extended ASCII. Standard ASCII uses 7 bits to represent 128 characters, including control characters, digits, uppercase and lowercase letters, and some symbols. Extended ASCII expands this to 256 characters by using the 8th bit, allowing for additional characters, symbols, and graphical representations, which vary by encoding system. Common extended ASCII sets include ISO-8859-1 and Windows-1252, which accommodate various languages and special characters.
How to find the ascii value of a letter?
To find the ASCII value of a letter in most programming languages, you can use a built-in function. For instance, in Python, you can use the ord() function, where ord('A') will return 65. Similarly, in JavaScript, you can use the charCodeAt() method on a string, like 'A'.charCodeAt(0), which will also give you 65. You can also look up ASCII values in a standard ASCII table.
Why do need Unicode when you have Ascii?
ASCII only has 127 standard character codes and only supports the English alphabet. While you can use the extended ASCII character to provide a set of 256 characters and thus support other languages there's no guarantee that other systems will use the same code page, so the characters will not display correctly across all systems (the characters you see will depend upon which code page is currently in use). Moreover, some languages, particularly Chinese, have thousands of symbols that simply cannot be encoded in ASCII. UNICODE encoding supports all languages and the first 127 symbols are also the same as ASCII, so all characters appear the same across all systems. UTF8 is the most common UNICODE encoding in use today because it uses one-byte per character for the first 127 characters and is therefore fully compliant with non-extended ASCII. If the most-significant bit is set then the character is represented by 2 or more bytes, the combination of which maps to the UNICODE encoding.
Why ASCII has 256 characters?
ASCII, or the American Standard Code for Information Interchange, originally defined 128 characters, using 7 bits for encoding. However, the extended version, known as Extended ASCII, uses 8 bits, allowing for 256 characters (2^8 = 256). This extension includes the original 128 ASCII characters plus an additional set of 128 characters, which include various symbols, letters from different languages, and graphical characters. The use of 8 bits became a standard in many systems, accommodating a broader range of characters for diverse applications.
