MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -MAC Addresses are 6 bytes (or 48 bits long), providing 281, 474, 976, 710, 656 addresses in theory. In order to make these addresses easier for humans to remember, these addresses are usually written as six two-digit hexadecimal numbers, such as 01:23:45:67:89:AB.

Detailed explanation-2: -These MAC addresses are 48 bits or 6 bytes long, so they are also known as MAC-48 or EUI-48. EUI stands for Extended Unique Identifier. It is written in hexadecimal characters as shown below: MAC addresses act as the physical addresses for local communications.

Detailed explanation-3: -In a LAN, each node is assigned a physical address, also known as a MAC/Ethernet address. This address is unique to each of the nodes on the LAN and is 6 bytes (48 bits) long, which is burned on the Ethernet card (also known as the network interface card). Ethernet is a byte-count protocol.

Detailed explanation-4: -Historically, MAC addresses are 48 bits long. They have two halves: the first 24 bits form the Organizationally Unique Identifier (OUI) and the last 24 bits form a serial number (formally called an extension identifier).

Detailed explanation-5: -The Format of a MAC Address Traditional MAC addresses are 12-digit (6 bytes or 48 bits) hexadecimal numbers. By convention, these addresses are usually written in one of the following three formats, although there are variations: MM:MM:MM:SS:SS:SS.
