Question

How does microprocessor differentiate between positive and negative number and bit pattern?

Answer 1

Microprocessors use binary, so all they have is ones and zeros (♪♫...and sometimes we ran out of ones...♪♫) Sorry. The chip notes negative numbers by the leading bit. If the chip can handle 8 bits if information, they use the first for the sign (0 is positive, 1 for negative) and the remaining 7 bits for thenumber from 0 to 12
