Question & Answer
Which of the following is a characteristic of a physical address?
1 Answer
Verified archiveThe correct answer is A. It is assigned by the device manufacturer.
A physical address, often referred to as a MAC (Media Access Control) address in networking, is a unique identifier that is assigned to a network interface card (NIC) by the manufacturer. This address is used for communication within a local network and is embedded in the hardware, making it consistent and unchanging under normal circumstances.
It’s important to remember that physical addresses are not used for routing data on the internet (that’s done by IP addresses), are not necessarily 32 bits long (they can vary), and typically cannot be changed by software.
