Bitwise Operations and Their Applications

What happens to a binary number when it is left shifted by one position?

• It is converted to decimal.

• It remains unchanged.

• It is multiplied by two.

• It is divided by two.

Which type of shift is suitable for unsigned binary numbers?

• Bitwise shift

• Logical shift

• Arithmetic shift

• Circular shift

In an arithmetic right shift, what happens to the most significant bit (MSB)?

• It is set to one.

• It is inverted.

• It is set to zero.

• It retains its original value.

What is the primary purpose of using a bitwise AND operation with a mask?

• To invert bits

• To toggle bits

• To set all bits to one

• To extract specific bits

How does a bitwise OR operation affect the bits in a binary sequence?

• It toggles bits where the mask is zero.

• It sets bits to one where the mask is one.

• It inverts all bits.

• It clears all bits.

What does the XOR operation do when applied to two identical bits?

• Inverts the bits

• Sets the result to one

• Leaves the bits unchanged

• Sets the result to zero

What is a practical application of bitwise operations in networking?

• Encrypting data

• Routing network traffic

• Rendering graphics

• Compressing files

How are IP addresses stored in computers?

• As ASCII characters

• As hexadecimal numbers

• As decimal numbers

• As 32-bit binary numbers

What is the purpose of using a mask with a bitwise AND operation on an IP address?

• To encrypt the address

• To isolate the network part

• To convert it to decimal

• To toggle the bits

Which version of IP is currently in use alongside IPv4?

• IPv3

• IPv5

• IPv7

• IPv6
