Abstract
To store larger 64-bit numbers in a high-level language such as Java, variables are declared as long, or in the C programming language long long is used. In assembly language a quad word, qword, or signed quad word, sqword, is used. Just as a 32-bit double word is twice as big as a regular 16-bit word, a 64-bit quad word is two times larger than a 32-bit double word or four times larger than a 16-bit word, thus the name quad word.
