The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n

The correct answer is:
(a) 65,536<\/strong><\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

A memory size of 64K<\/strong> means it contains 64 \u00d7 1024 bytes<\/strong> because 1K = 1024 bytes<\/strong>.<\/p>\n\n\n\n

Step-by-Step Calculation:<\/h4>\n\n\n\n
    \n
  1. Understanding the ‘K’ in 64K:<\/strong>\n
      \n
    • ‘K’ stands for kilo<\/strong>, which is 1024<\/strong> in computing (not 1000 as in standard metric notation).<\/li>\n\n\n\n
    • So, 64K = 64 \u00d7 1024 bytes<\/strong><\/li>\n\n\n\n
    • 64\u00d71024=65,53664 \\times 1024 = 65,536 bytes<\/li>\n<\/ul>\n<\/li>\n\n\n\n
    • 1 Byte = 8 Bits:<\/strong>\n
        \n
      • Since each memory location stores 1 byte<\/strong>, and 1 byte = 8 bits<\/strong>, each memory location is an 8-bit word<\/strong>.<\/li>\n<\/ul>\n<\/li>\n\n\n\n
      • Finding the Number of 8-bit Words:<\/strong>\n
          \n
        • Since each byte is an 8-bit word, the number of 8-bit words in 64K memory is simply the number of bytes, which is 65,536<\/strong>.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n

          Conclusion:<\/h3>\n\n\n\n

          A 64K memory<\/strong> contains 65,536<\/strong> words of 8 bits each<\/strong>.<\/p>\n\n\n\n

          This calculation applies to standard memory architectures where each addressable memory unit (byte) is 8 bits. If a system had a different word size (e.g., 16-bit or 32-bit), then the calculation would differ, but in this case, for 8-bit words, the answer remains 65,536<\/strong>.<\/p>\n\n\n\n

          Alternative Answer Choices Analysis:<\/h4>\n\n\n\n
            \n
          • (b) 64,536<\/strong> – Incorrect (off by 1000).<\/li>\n\n\n\n
          • (c) 65,436<\/strong> – Incorrect (off by 100).<\/li>\n\n\n\n
          • (d) 65,546<\/strong> – Incorrect (off by 10).<\/li>\n\n\n\n
          • (e) 65,556<\/strong> – Incorrect (off by 20).<\/li>\n<\/ul>\n\n\n\n

            Thus, the correct choice is (a) 65,536<\/strong>.<\/p>\n\n\n\n

            Now, I will generate an image representing this concept.<\/p>\n\n\n\n

            I’ve provided an image illustrating the concept of 64K memory, showing its structure and breakdown into 8-bit words. Let me know if you need any modifications or further explanations!<\/p>\n\n\n\n
