only uses one byte (8 bits) to encode English characters
uses two bytes (16 bits) to encode the most commonly used characters.
uses four bytes (32 bits) to encode the characters.
Depends on what you refer to as Unicode. Typically the ones you will see is UTF-8 which uses from up to one to three bytes per character (the two or three-byte characters are usually for characters used in various other languages that are not already covered under the ASCII codepage). Otherwise, the convention states that Unicode is UTF-16.
That depends on the character code used:baudot - 5 bits per character - 320 bitsFIELDATA - 6 bits per character - 384 bitsBCDIC - 6 bits per character - 384 bitsASCII - 7 bits per character - 448 bitsextended ASCII - 8 bits per character - 512 bitsEBCDIC - 8 bits per character - 512 bitsUnivac 1100 ASCII - 9 bits per character - 576 bitsUnicode UTF-8 - variable bits per character - depends on the characters in the textUnicode UTF-32 - 32 bits per character - 2048 bitsHuffman coding - variable bits per character - depends on the characters in the text
16 bits. Java char values (and Java String values) use Unicode.
it support the 65000 different universal character.
A character in ASCII format requires only one byte and a character in UNICODE requires 2 bytes.
"recommended setting" There are 19 characters including the space between the two words. If the old convention of using 1 byte to represent a character, then we would need (19 x 8) which is 152 bits. If we use unicode as most modern computers use (to accommodate all the languages in the world) then 2 bytes will represent each character and so the number of bits would be 304.
8 bits = 64 character
That depends what encoding is used. One common (fairly old) encoding is ASCII; that one uses one byte for each character (letter, symbol, space, etc.). Some systems use 2 bytes per character. Many modern systems use Unicode; if the Unicode characters are stored as UTF-16 - a fairly common encoding scheme - many common characters will still use a single byte, while many special symbols (for example, accented characters) will take up two bytes. The number of bits is simply the number of bytes multiplied by 8.
ASCII = 7 bit Unicode = 16 bits UTF-8 =8 bit
One character typically represents one byte, which is composed of 8 bits. Therefore, there are 8 bits in one character. This means that for each character, you can think of it as equivalent to 8 bits.
Each hexidecimal character represents 4 bits, therefore 256 bits takes 256 / 4 = 64 characters.
