Explanation: When writing a Media Access Control (MAC) address, the letter “B” is equivalent to the hexadecimal number 11, and vice versa. The notation used to write MAC addresses is typically hexadecimal, and the values 10-15 in base-16 are represented by the letters A through F. MAC addresses are always expressed in hexadecimal. Therefore, the number 11 in hexadecimal represents the letter B in decimal notation. For instance, the number 11 is represented by the “2B” in the MAC address “00:1A:2B:3C:4D:5E,” where “2B” is the value of the third pair of hexadecimal digits.
