Which of the following numbering systems is used to represent MAC addresses?

While MAC addresses are fundamentally composed of binary bits, they are not typically represented directly in a long binary string for readability and ease of use in documentation or configuration.

Decimal is a base-10 system that is not used for the standard representation of MAC addresses, which are inherently tied to binary and thus more efficiently represented by hexadecimal.

Octal is a base-8 numbering system that is not standard for representing MAC addresses, which are 48 bits long and require hexadecimal for compact representation.

MAC (Media Access Control) addresses are 48-bit identifiers universally represented as twelve hexadecimal digits, typically grouped into six pairs separated by hyphens or colons, such as `00-1A-2B-3C-4D-5E`. Hexadecimal is chosen because it conveniently represents four binary bits with a single character, making long binary strings like MAC addresses more readable and concise.
