Question 1

What are bitwise operations?

Accepted Answer

Bitwise operations treat integer values as binary bit sequences and perform logical operations on each bit. They include AND (&), OR (|), XOR (^), NOT (~), left shift (<<), and right shift (>>), and are widely used in low-level data processing, flag management, and cryptography.

Question 2

What is the difference between AND and OR operations?

Accepted Answer

AND produces 1 only when both bits are 1. OR produces 1 when either bit is 1. AND is commonly used for bit masking (extracting specific bits), while OR is used for setting bits (turning flags on).

Question 3

When is XOR used?

Accepted Answer

XOR (exclusive OR) returns 1 when the two bits differ. It is widely used in encryption, checksum calculations, value swapping, and difference detection. A particularly useful property is that XORing a value with itself produces 0.

Question 4

Is my data sent to a server?

Accepted Answer

No, all processing is done within your browser. Your data is never sent to any external server.

Operation	Symbol	Description
AND	&	Result is 1 only if both bits are 1. Used for bit masking.
OR	\|	Result is 1 if either bit is 1. Used for setting flags.
XOR	^	Result is 1 if bits differ. Used for encryption and swapping.
NOT	~	Inverts all bits. Used for complement calculations.
Left Shift	<<	Shifts bits left. Equivalent to multiplying by 2^n.
Right Shift	>>	Shifts bits right. Equivalent to dividing by 2^n.
