Expert Solution & Answer
Chapter 3, Problem 1RQ
Program Description Answer
OUI of MAC address is unique.
Hence, the correct answer is option “B”.
Expert Solution & Answer
Explanation of Solution
The OUI:
- • OUI in networking stands for Organizationally Unique Identifier.
- • It is the memory of first 24 bits of a Media Access Control (MAC) address that is used for identifying a vendor uniquely.
- • It is the first three parts of 8bits each used for data communication in computing.
- • It is used in finding the Network Interface Controller (NIC) manufacturer.
Explanation for incorrect options:
The network identifier:
The network identifier is used for finding the computers or devices present on any local network or intranet.
Hence, the option “A” is wrong.
The device identifier:
The device identifier is used for categorizing the devices.
Hence, the option “C” is wrong.
The physical address:
A physical address is used for defining and understanding a cell which is related to main memory.
Hence, the option “D” is wrong.
