*Do you know what MAC address is?

A MAC address (Media Access Control address) is a unique identifier assigned to the network interface card (NIC) of a device. Unlike an IP address, which can change depending on the network, the MAC address is permanent and ensures that devices can communicate efficiently within a local network. It is crucial for device identification, data transmission, and network security.

The MAC address consists of 12 hexadecimal characters, split into two parts: the Organizationally Unique Identifier (OUI), which identifies the manufacturer, and the Device Identifier, which uniquely identifies the device. These addresses are used for network communication, device management, and controlling network access.

A MAC address is globally unique to each device.
It helps devices communicate within a local network.
MAC addresses play a role in network security, such as through MAC filtering.
They assist in device identification and management for network administrators.
They are used for DHCP and IP address assignment on networks.
