    The MAC address never changes. True or False

    Explanation
    False. The MAC address, also known as the Media Access Control address, is a unique identifier assigned to a network interface card. While it is true that the MAC address is typically assigned by the manufacturer and remains constant for the lifetime of the device, there are methods to change or spoof the MAC address. This can be done for various reasons, such as enhancing privacy or bypassing network restrictions. Therefore, it is not accurate to say that the MAC address never changes.
