The quantity of double word is<br>a) 16 bits<br>b) 32 bits<br>c) 4 bits<br>d) 8 bits<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-ast-global-color-1-color\">The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Correct Answer: b) 32 bits<\/strong><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Explanation (300+ Words):<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In computer systems, data is stored and processed in different units such as <strong>bits<\/strong>, <strong>nibbles<\/strong>, <strong>bytes<\/strong>, <strong>words<\/strong>, and <strong>double words<\/strong>. Understanding these units is essential for grasping how memory and processors handle data.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Let\u2019s break down these data units step by step:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>1 bit<\/strong> is the smallest unit of data in computing, representing a binary value \u2014 either 0 or 1.<\/li>\n\n\n\n<li><strong>1 nibble<\/strong> consists of <strong>4 bits<\/strong>.<\/li>\n\n\n\n<li><strong>1 byte<\/strong> is made up of <strong>8 bits<\/strong> and can represent 256 different values (2\u2078).<\/li>\n\n\n\n<li><strong>1 word<\/strong> typically refers to the standard unit of data that a processor handles in one operation. For many systems (especially 16-bit systems), <strong>1 word = 16 bits<\/strong>.<\/li>\n\n\n\n<li>A <strong>double word (or DWORD)<\/strong>, as the name suggests, is <strong>twice the size of a word<\/strong>. So if one word is 16 bits, a double word is: $$<br>16 \\text{ bits} \\times 2 = 32 \\text{ bits}<br>$$<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, <strong>a double word is equal to 32 bits<\/strong>, and this is the correct answer to the question.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Practical Usage:<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Many computer architectures, especially those based on Intel x86, define a <strong>word as 16 bits<\/strong>. A double word is then <strong>32 bits<\/strong>, and a <strong>quad word<\/strong> would be <strong>64 bits<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In programming, especially in lower-level languages like <strong>C<\/strong> or <strong>Assembly<\/strong>, data types like <code>DWORD<\/code> (double word) are common. For instance, in Windows programming, <code>DWORD<\/code> is used as a data type to represent 32-bit unsigned integers.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Why It Matters:<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Understanding the size of data types is crucial for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Memory allocation<\/li>\n\n\n\n<li>Data alignment<\/li>\n\n\n\n<li>Understanding how much space variables occupy<\/li>\n\n\n\n<li>Optimizing software performance<\/li>\n\n\n\n<li>Writing hardware drivers or interacting directly with memory addresses<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">In conclusion, the correct answer is <strong>(b) 32 bits<\/strong>, as a double word is defined to be twice the size of a 16-bit word, making it <strong>32 bits<\/strong> in total.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/05\/image-79.png\" alt=\"\" class=\"wp-image-217825\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>.
