What is the result of binary addition 1 + 1 + 1?

• 10

• 01

• 11

• 100

Why do binary addition operations always move from right to left?

• Because the left bits are always 0

• It follows the decimal method, aligning columns

• It matches ASCII

• The CPU prefers left-first

What does the binary addition of 01100101 and 00011110 produce?

• 10000011

• 01111100

• 11100000

• 10100001

In which situation is a carry generated during binary addition?

• When 0 + 1

• When 1 + 1

• When adding two zero bits

• When 1 + 0

Why can 8-bit systems not store the number 300?

• 300 is a character

• 300 is larger than 255, the 8-bit max

• 8-bit systems use decimals

• Bits don’t allow numbers that high

Which of the following is the binary representation of the decimal number 255?

• 11111111

• 11111110

• 100000000

• 01111111

Why does 11111111 + 00000001 result in 00000000 in 8-bit binary?

• The system resets on overflow

• The CPU crashes

• Binary ignores extra bits

• The values cancel out

What best explains why overflow is a serious issue in programming?

• It causes CPU overheating

• It replaces data with incorrect values

• It slows down RAM

• It prevents user input

In a CPU, which component detects an overflow?

• ALU’s overflow flag

• Control unit

• Hard drive

• Display driver

What would be the result of 00110110 << 2 (left shift by 2)?

• 11011000

• 00011011

• 00110110

• 00000000
