Bit is a portmanteau of binary digit.

A byte is 8 bits.

A nibble is 4 bits (half a byte).

Is there a word for a pair of bytes?

It is word which is 16 bits.

They are (in order of increasing size)


Please note that a word is the standard memory bus width in your architecture. It can be 8 bits or 16 bits or 32 bits or 64 bits based on the CPU.

You can read more about assembler(binary) here (this is a random link I found on google for your reference, but I verified that the information is correct about the above mentioned. Search on google).

    If word is so flexible, how can it definitively mean "a pair of bytes" if byte means only eight bits?

  • Unless otherwise excited, it decays to the ground state. Mar 19, 2013 at 14:31
  • @Robusto: A word is 16 bits in a conventional sense. As a matter of fact, the most common architecture even in the present day is x86-32, in which a word is 16 bits. Like @coleopterist mentioned in his comment, more details can be found at en.wikipedia.org/wiki/Units_of_information

    @Fr0zenFyr A word is 32 bits on x86-32 and 64 bits on x86-64. Some x86-specific technical documents use "word" to mean a 16-bit value for consistency with documentation and software written for 8086 processors, which had 16-bit words. This usage of "word" does not mean that x86 processors use 16-bit words. See the list of word sizes at en.wikipedia.org/wiki/Word_(computer_architecture)

I will offer this up as a suggestion, though I don't believe it was ever used in serious writing. A playte is unambiguously 16 bits, and also; chawmp in the context of a 32 bit machine.

see here and here

I would've just commented on the previous answer but I don't have enough reputation yet, so I'll leave an alternate answer instead.

Also, I believe nybble is the correct spelling for four bits.
