A word is 2 bytes, a Dword or Double-Word is 4 bytes. Dwords are commonly used for integer values, smaller ranges can use bytes or words, but I think anything below -32768 and above +32768 needs to be a Dword, a common example would be a 32-bit colour value.

I reckon DB supports them when loading or saving files, but as a default, Dword would be used on any integer value anyway.
