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.
A byte is abbreviated with a B. (A bit is abbreviated with a small b.) Computer storage is usually measured in byte multiples. For example, an 820 MB hard drive holds a nominal 820 million bytes-or megabytes-of data. Byte multiples are based on powers of 2 and commonly expressed as a rounded off decimal number. For example, one megabyte (one million bytes) is actually 1,048,576 (decimal) bytes.
