Explain the characteristics of the cmp instructions?..

Answer / Charu Singh

The CMP instruction in the 8086 microprocessor compares two operands and sets the flags according to the result. The operands can be registers, memory locations, or immediate values. The main characteristics are: subtraction without affecting the accumulator, setting flags based on the comparison (ZF, SF, OF, AF), and leaving the AL/AX unchanged if no register is specified.
