Computer Science – Data representation | e-Consult

Explanation:

When adding two 8-bit binary numbers, each bit position is added, along with the carry-over from the previous position. If the sum of the bits in a position is 2 or more, a carry bit is generated. This carry bit is propagated to the next higher bit position. The carry bit represents that the sum exceeds the value that can be represented in the current bit position. The carry is added to the next more significant bit position.

Diagram:

The carry bit is shown as '1' in the 'Sum' column. The final carry bit, if any, is often ignored depending on the application.
