ITPEC IP April 2020 — Question 1 of 100

The sum is 11000101. Binary 01011010 equals decimal 90, and 01101011 equals decimal 107. Their sum is 197, which is 128 + 64 + 4 + 1 and therefore has the 8-bit representation 11000101.

Answer (d)

Why not others:
- each other bit pattern represents a different decimal value

- no overflow occurs because 197 fits within the unsigned 8-bit range 0 through 255

Key rule: Binary addition follows the same place-value principle as decimal addition, with a carry whenever a column totals two or more.
