| Open Systems Interconnection model, a conceptual framework that standardizes the functions of a communication system into seven layers. | The second layer in the OSI model, responsible for the reliable transmission of data frames between network nodes. |
| An IP address that is reserved for internal use within a private network. | A globally unique IP address that is assigned to a device connected to a public network. |
| A unique identifier assigned to network interfaces for communications on the physical network segment. | The process used to translate private IP addresses to public IP addresses, and vice versa. |
| The practice of modifying the media access control address of a network device to masquerade as a different device or to bypass access controls. |
