LMAO..! 568, Airport Road.. XD

ISRO's GOD level comedy..XD

Answer 1

Answer is D

The standard (IEEE 802) format for printing MAC-48 addresses in human-friendly form is six groups of two hexadecimal digits, separated by hyphens (-) in transmission order (e.g. 01-23-45-67-89-ab). This form is also commonly used for EUI-64 (e.g. 01-23-45-67-89-ab-cd-ef).^[3] Other conventions include six groups of two hexadecimal digits separated by colons (:) (e.g. 01:23:45:67:89:ab), and three groups of four hexadecimal digits separated by dots (.) (e.g. 0123.4567.89ab); again in transmission order

Answer 3

ans is (d)

 a is not ans because A MAC address is given to a network adapter when it is manufactured. It is hardwired or hard-coded onto your computer's network interface card (NIC) and is unique to it. Something called the ARP (Address Resolution Protocol) translates anIP address into a MAC address.

A "media access control address" (MAC address) also called "Physical Address" is a unique identifier assigned to network interfaces for communications on the physical network segment. MAC addresses are used as a network address for most IEEE 802 network technologies, including Ethernet and WiFi.

The original IEEE 802 MAC address comes from the original Xerox Ethernet addressing scheme. This 48-bit address space contains potentially 248 or 281,474,976,710,656 possible MAC addresses. All three numbering systems use the same format and differ only in the length of the identifier.
