Interface | A connection to a network. Unlike a port, an interface is |

| not all interfaces are ports). |
Internet | A |
| vast chain of private and public LANs. |
Inter- | The capacity to function in conjunction with other devices. |
operability | Used primarily to indicate the ability of different vendors’ |
| networking products to work together cohesively. |
