      \ud83e\udde0 Explanation (300 words)<\/strong><\/h3>\n\n\n\n

      Number systems are different ways to represent numbers using various bases. The decimal system<\/strong> is base-10, the most common in everyday life, using digits 0\u20139. However, computers use binary (base-2)<\/strong> because they operate with two states: ON and OFF, represented by 1 and 0.<\/p>\n\n\n\n

      To convert decimal to binary<\/strong>, divide the number by 2 repeatedly and record the remainders. Reading the remainders from bottom to top gives the binary number.<\/p>\n\n\n\n

      For example:<\/p>\n\n\n\n

        \n
      • 81 \u2192 Binary:\n
          \n
        • 81 \u00f7 2 = 40, remainder 1<\/li>\n\n\n\n
        • 40 \u00f7 2 = 20, remainder 0<\/li>\n\n\n\n
        • 20 \u00f7 2 = 10, remainder 0<\/li>\n\n\n\n
        • 10 \u00f7 2 = 5, remainder 0<\/li>\n\n\n\n
        • 5 \u00f7 2 = 2, remainder 1<\/li>\n\n\n\n
        • 2 \u00f7 2 = 1, remainder 0<\/li>\n\n\n\n
        • 1 \u00f7 2 = 0, remainder 1
          \u21d2 1010001<\/strong><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n

          Octal (base-8)<\/strong> uses digits 0\u20137. Group binary digits in 3s (from right), then convert to octal. For 81:<\/p>\n\n\n\n

            \n
          • Binary: 1010001<\/code> \u2192 Pad to 8 bits: 01010001<\/code><\/li>\n\n\n\n
          • Groups: 010 100 001<\/code> \u2192 2 4 1 \u2192 Octal = 121<\/strong><\/li>\n<\/ul>\n\n\n\n

            Hexadecimal (base-16)<\/strong> uses 0\u20139 and A\u2013F (where A = 10 to F = 15). Group binary digits in 4s:<\/p>\n\n\n\n

              \n
            • Binary of 81: 01010001<\/code> \u2192 Groups: 0101 0001<\/code> \u2192 5 and 1 \u2192 Hex = 51<\/strong><\/li>\n<\/ul>\n\n\n\n

              These conversions are essential in computing, as binary is used for logic, octal and hex for simplifying binary representation in programming and hardware.<\/p>\n","protected":false},"excerpt":{"rendered":"
