A bit is one binary digit eg 0 or 1 a byte is eight bits, or two hex digits a nibble is half a byte or 1 hex digit words get a bit more complex originally it was the number of bytes required to cover the range of addresses available in memory. You might hear an advertisement that says, this computer has a 32-bit pentium processor with 64 megabytes of ram and 21 gigabytes of hard disk space and many howstuffworks articles talk about bytes (for example, how cds work . In computer science a byte is a unit of measurement of information storage, that equals '8 bits', can be used to represent letters and numbers for example, the number 01000001 is 8 bits long, and represents the letter a in 8-bit encoding.
The byte is a unit of digital information that most commonly consists of eight bits, representing a binary numberhistorically, the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable unit of memory in many computer architectures the size of the byte has historically been hardware dependent and no definitive. In computing, a word is the natural unit of data used by a particular processor design a word is a fixed-sized piece of data handled as a unit by the instruction set or the hardware of the processor the number of bits in a word (the word size, word width, or word length) is an important characteristic of any specific processor design or computer architecture. Bits, bytes and words what is a bit bit is short for 'binary digit' it's a single digit in a binary number, and it can be either 1 or 0 inside a computer, you can think of a bit as being a mechanical switch, which can be either switched on or off (the earliest computers actually stored information in memory using mechanical switches, with electromagnets to turn each one on or off.
