===Datalink Layer (2)===
The Datalink layer is in charge of ensuring end-to-end validity of the data being exchanged. This layer is logically split into two sublayers, The Media Access Control (MAC) Sublayer and the Logical Link Control (LLC) Sublayer.<ref name="docs.oracle.com"/><ref name="support.microsoft.com"/><ref name="academia.edu"/>

*The Media Access Control (MAC) Sublayer determines the actual physical address of the hosts. To do this, it uses MAC addresses for its communication with other devices on the network. Unlike the IP addresses which the Network Layer uses, MAC addresses (also known as Physical addresses, Layer 2 addresses, or Hardware addresses) are assigned to each device at the time of manufacture, and are not usually changed (although this is sometimes possible, it will never be done automatically). These are therefore reliable identifiers within a local network. are also known as Physical addresses, Layer 2 addresses, or Hardware addresses.<ref name="docs.oracle.com"/><ref name="support.microsoft.com"/><ref name="academia.edu"/>
