8 bits (bit) = 1 bytes (byte), 1024 bytes =1kb;
Mentions the byte, must again mention "the word" This unit of measure: "The word" consists of a number of bytes, the number of bits of the word is called word length, words are the number of binary numbers corresponding to the lengths. Different machines have different lengths of word. For example, a 8-bit machine, its 1 characters equals 1 bytes, and the word length is 8 bits. If it is a 16-bit machine, then its 1 characters are made up of 2 bytes, with a word length of 16 bits.
Pre-DOS is 8-bit, the latter DOS is 16-bit, Win9x is based on DOS, so is 16-bit, NT core Windows is 32-bit, and now also has 64-bit XP/2003,CPU also has 64-bit, This operating system and CPU are referred to as bit meaning, that is, the length of the binary number.
BYTE is fixed by 8-bit binary composition, 64-bit system represents a 64-bit binary represents a word, converted to byte is 64/8=8, that is, 8 bytes constitute a word, 32-bit system is 32/8=4,4 byte represents a word.
8 bit (bit) = 1 bytes (byte)
