American Standard Code for Information Interchange. ASCII is a form of character encoding.
Character encoding is the way that a computer interprets and then displays a file as text. Each encoding has its own set of characters that it can match to the file. For example, the Windows-1252 encoding, used for Western European languages, contains characters like accented vowels that are used in Spanish, French, etc. However, an encoding used for Russian family languages would include characters from the Cyrillic alphabet. Most encodings use 8 bits to encode a single character, which allows the encoding to contain up to 256 characters. Unicode is a newer encoding system that uses a significantly different system for character encoding that allows it to surpass the 256 character limit. Over 100,000 characters are currently supported by Unicode/UTF-8.
The American Standard Code for Information Interchange is a character-encoding scheme based on the ordering of the English alphabet.
ASCII (American Standard Code for Information Interchange) is a character-encoding scheme that was standardised in 1963. There is no encoder required to create ASCII. Every machine supports it as standard, although some implement it via UNICODE. The only difference is in the number of bytes used to represent each character. The default is one byte per character yielding 128 standard encodings that map exactly with the first 128 characters in UNICODE encoding.
Encription
The Unicode system was invented to create a universal character encoding standard that could support multiple languages and scripts. This standard allows for the representation of text in different languages and writing systems across various platforms and devices. Unicode helps to ensure consistency and interoperability in text encoding.
Unicode is an extensive encoding scheme that can represent all characters of all languages worldwide. It is designed to be a universal character encoding standard, accommodating scripts, symbols, emojis, and characters from various writing systems. Unicode ensures interoperability across different platforms and systems by providing a unique code point for each character.
The number of bits in a message depends on its size and the encoding used. For example, if a message contains 100 characters and uses standard ASCII encoding, it would consist of 800 bits (100 characters x 8 bits per character). In general, to determine the total bits, multiply the number of characters by the number of bits per character based on the encoding scheme.
What encoding scheme is used by the 802.11a and 802.11g standards but not by the 802.11b standard?
Unicode is a universal character encoding standard that assigns a unique number to every character in many different languages and scripts, allowing for consistent representation of text across different systems and applications. It supports a vast range of characters and symbols, making it essential for internationalization and multilingual support in software development.
binary stream reads data(8-bits) irrespective of encoding, character stream reads two bytes as character and convert into locale stream using unicode standard. binary stream better for socket reading and character stream is better for client input reading
The decimal value for the letter 'n' in the ASCII character encoding is 110. In Unicode, 'n' also has the same decimal value of 110. This value corresponds to its representation in both standard character sets used in computing.
