Data is moved from one PC to another in discrete chunks called packets or frames. The terms packet and frame are interchangeable.

MAC address is abbreviated form of Media Access Control.MAC address represent in hexadecimal format and it is 48 byte addressing scheme.eg:00-1c-c0-69-87-81.So each quarter consists two 4 byte code and finally 48 bytes.
The MAC address is stored within the NIC(Network Interface Card).And the main purpose of MAC address is to uniquely identify a system.The MAC address works in Layer 2(Data link layer) of ISO model.Where layer 2 is only associated with MAC address or Physical address.And the layer 2 device switch contains MAC address table to occur switching between source and destination.
MAC address is unique because the MAC address is within a NIC card.In this world there is so many NIC manufactures.So that IANA(Internet assigned numbers authority)has given unique identification number to each NIC manufacture and which is 24 byte long.And the remaining 24 byte is uniquely assign by the NIC manufacture itself.So that it won't repeat within the manufacture itself.
Thats why it name as Unique addressing. Source: CoolInterview.com

In computer networking, a Media Access Control address (MAC address) is a unique identifier assigned to most network adapters or network interface cards (NICs) by the manufacturer for identification, and used in the Media Access Control protocol sublayer. Source: CoolInterview.com

Short for Media Access Control address, a hardware address that uniquely identifies each node of a network. In IEEE 802 networks, the Data Link Control (DLC) layer of the OSI Reference Model is divided into two sublayers: the Logical Link Control (LLC) layer and the Media Access Control (MAC) layer. The MAC layer interfaces directly with the network medium. Consequently, each different type of network medium requires a different MAC layer.
On networks that do not conform to the IEEE 802 standards but do conform to the OSI Reference Model, the node address is called the Data Link Control (DLC) address.

In computer networking, a Media Access Control address (MAC address) is a unique identifier assigned to most network adapters or network interface cards (NICs) by the manufacturer for identification, and used in the Media Access Control protocol sub-layer. If assigned by the manufacturer, a MAC address usually encodes the manufacturer's registered identification number. It may also be known as an Ethernet Hardware Address (EHA), hardware address, adapter address, or physical address Source: CoolInterview.com
