Is a word 16 or 32 bits?
In x86 assembly language WORD , DOUBLEWORD ( DWORD ) and QUADWORD ( QWORD ) are used for 2, 4 and 8 byte sizes, regardless of the machine word size. A word is typically the “native” data size of the CPU. That is, on a 16-bit CPU, a word is 16 bits, on a 32-bit CPU, it’s 32 and so on.
How big is a word in 32-bit?
Two bytes together as in a 16 bit machine make up a word , 32 bit machines are 4 bytes which is a double word and 64 bit machines are 8 bytes which is a quad word.
What type is DWORD?
A dword, which is short for “double word,” is a data type definition that is specific to Microsoft Windows. When defined in the file windows. h, a dword is an unsigned, 32-bit unit of data. It can contain an integer value in the range 0 through 4,294,967,295.
How big is a word in x86?
16 bits
In the x86 PC (Intel, AMD, etc.), although the architecture has long supported 32-bit and 64-bit registers, its native word size stems back to its 16-bit origins, and a “single” word is 16 bits. A “double” word is 32 bits. See 32-bit computer and 64-bit computer.

What is word in C?
A word is an integer number of bytes for example, one, two, four, or eight. When someone talks about the “n-bits” of a machine, they are generally talking about the machine’s word size. For example, when people say the Pentium is a 32-bit chip, they are referring to its word size, which is 32 bits, or four bytes.
What is word in x86?
x86 Architecture In the x86 PC (Intel, AMD, etc.), although the architecture has long supported 32-bit and 64-bit registers, its native word size stems back to its 16-bit origins, and a “single” word is 16 bits. A “double” word is 32 bits. See 32-bit computer and 64-bit computer.
How long is word in C?
WORD in Windows APIs means 2 bytes. It was originally used to refer to the pointer-size (as in a CPU with a word length of 16 bits).
What DWORD means?
Filters. (computing) A numerical value of twice the magnitude of a word, typically 32 bits. noun.
