Understanding Binary Shift Operations

What is a binary shift operation?

• A method to add two binary numbers.

• A technique to move bits left or right in a binary number.

• A process to convert binary numbers to decimal.

• A way to multiply binary numbers by 10.

What is the main difference between an arithmetic shift and a logical shift?

• Arithmetic shifts preserve the sign bit, while logical shifts do not.

• Logical shifts preserve the sign bit, while arithmetic shifts do not.

• Both shifts preserve the sign bit.

• Neither shift preserves the sign bit.
