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.
It can also be used to represent the 1000 bytes or 103, which is the decimal interpretation. This may be a little confusing but note that binary KB is bigger than the decimal one by 24 bytes. When represented in the binary system MB is 1,048,576 bytes or 220 bytes and it stands for megabyte. However, in the decimal system, it stands for 1,000,000 bytes or 106 bytes. In the decimal system, MB stands for megabits. 1 bit = 1 or 0. 1 nibble = 4 bits. 1 byte = 8 bits. 1 KB (one Kilobyte) = 1024 bytes.
