বিট বাইট ওয়ার্ড Bit byte and Word
1) Bit: Short for binary digit, the smallest unit of information on a
machine"computer". A single bit can hold only one of two values: 0 or 1.
2) Byte :A sequence of adjacent bits, usually eight, operated on as a unit by a computer.
3) Word :The size of a word varies from one computer to another, depending on the CPU. For computers with a 16-bit CPU, a word is 16 bits (2 bytes). On large mainframes, a word can be as long as 64 bits (8 bytes).Some computers and programming languages distinguish between shortwords and longwords. A shortword is usually 2 bytes long, while a longword is 4 bytes.
-------summary:-------
1 bit = 0 or 1
1 Byte = 8 bits
1 word = 2 Bytes = 2 X (8 bits) = 16 bits
Double Word = 4 Bytes=4 X (8 bits)= 32 bits
