Unicode can be implemented by different character encodings. The most commonly used encodings are UTF-8, UTF-16 and the now-obsolete UCS-2. UTF-8 uses one byte for any ASCII character, all of which have the same code values in both UTF-8 and ASCII encoding, and up to four bytes for other characters.
Since a bit alone cannot represent enough data to be useful to humans, bits are grouped together, eight at a time, to form a byte. In other words, two bytes are equivalent to 16 bits, and three bytes the same as 24 bits. The more complex a document or application is, the more bytes are required to represent and store it in a computer. Prefixes Modern computers deal in very large amounts of bytes.
