1.3 Network Representations and Topologies

Network Interface Card (NIC)

A NIC physically connects the end device to the network.

3) Which type of network topology lets you see which end devices are connected to which intermediary devices and what media is being used? - Physical topology - Logical topology

- Logical topology

Which type of network topology lets you see the actual location of intermediary devices and cable installation? - Physical topology - Logical topology

- Physical topology

Logical topology diagram

Logical topology diagrams illustrate devices, ports, and the addressing scheme of the network, as shown in the figure. You can see which end devices are connected to which intermediary devices and what media is being used.

2) Which connections are specialized ports on a networking device that connect to individual networks? - Port - NIC - Interface

- Interface

Which connection physically connects the end device to the network? - Port - NIC - Interface

- NIC

Physical Port

A connector or outlet on a networking device where the media connects to an end device or another networking device.

Physical topology diagram

Physical topology diagrams illustrate the physical location of intermediary devices and cable installation, as shown in the figure. You can see that the rooms in which these devices are located are labeled in this physical topology.

Interface

Specialized ports on a networking device that connect to individual networks. Because routers connect networks, the ports on a router are referred to as network interfaces.
