सही: ० / ०
-
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.
