The octal number 745 expressed in binary is:
सही उत्तर: घ) 111100101
Each octal digit maps to 3 bits: 7 = 111, 4 = 100, 5 = 101, giving 111100101.

The Excess-3 code of the decimal digit 6 is:
सही उत्तर: ख) 1001
Excess-3 code = binary of (digit + 3); 6 + 3 = 9 = 1001.

Using 8-bit 2's complement representation, the range of integers that can be represented is:
सही उत्तर: ग) -128 to +127
An n-bit 2's complement number ranges from -2^(n-1) to 2^(n-1)-1, i.e. -128 to +127 for n = 8.

The 8-bit 2's complement representation of -1 is:
सही उत्तर: क) 11111111
+1 = 00000001; inverting gives 11111110 and adding 1 gives 11111111.

In 8-bit sign-magnitude representation, the number -25 is written as:
सही उत्तर: घ) 10011001
+25 = 00011001; in sign-magnitude only the sign (leftmost) bit is set to 1, giving 10011001.

The 1's complement of the binary number 101100 is:
सही उत्तर: ख) 010011
1's complement is obtained by inverting every bit: 101100 becomes 010011.
