Solution
The statement that is true about MAC (Media Access Control) addresses is: "A MAC address is a unique identifier assigned to network interfaces for communications on the physical network segment."
Explanation:
- MAC addresses are not used to identify devices on the Internet. IP addresses are used for that purpose.
- MAC addresses are not 128-bit hexadecimal numbers. They are actually 48-bit hexadecimal numbers.
- MAC addresses are indeed unique identifiers assigned to network interfaces for communications on the physical network segment. They are used for addressing on the Data Link Layer (Layer 2) of the OSI model.
- While it is technically possible to change a MAC address with software, it is not easily done and is generally not recommended, as it can lead to network issues. Therefore, the statement "MAC addresses can be easily changed by software on any network device" is not entirely accurate.
