| Bandwidth | The range of cycle frequencies that transmission media can physically accommodate. |
| Throughput | The measure of the amount of data transmitted within a specified time period, and is usually measured in bits per second (bps). |
| Attenuation | The tendency of electromagentic waves to weaken or become distorted during transmission. |
| Interference | A phenomenon occurs when undesirable electromagnetic waves affect the desired signal. |
| SignalCapture | The interception of electromagnetic waves, allowing the message to be copied or diverted. |

| Patchpanel | Provides multiple ports, which use patch cables to connect to other connectivity devices. |
| Coaxial | A type of cable made of two conductors that share a common axis, formed by a sold-copper wire. |
| Fiberoptic | Type of cable made of light -conducting glass. |
| Singlemode | Type of fiber optic cable that allows only one light path. |
