How signals are altered to carry information (amplitude, frequency, phase)

• Modulation

• Demodulation

• Transmission

• Encoding

When two devices on a link don’t agree on data speed or duplex mode

• Speed and duplex mismatch

• Data collision

• Network congestion

• Signal degradation

The actual amount of data that’s successfully sent over a network

• Latency

• Throughput

• Bandwidth

• Packet Loss

The loss of signal quality over distance or interference

• Signal degradation

• Signal amplification

• Signal distortion

• Signal attenuation

The process of converting data into a digital signal for transmission

• Decoding

• Encoding

• Transmitting

• Compressing

Unit to measure signal strength (or loss)

• dB (decibels)

• V (volts)

• A (amperes)

• W (watts)

The total time for a signal to go from your device to a destination and back

• RTT (round trip time)

• MTT (mean trip time)

• TT (total time)

• DTT (direct trip time)

Data can be sent and received at the same time

• Half-duplex

• Full-duplex

• Simplex

• Multiplex

A screw-on connector for coaxial cables, often used in TV and cable modems.

• F-type connector

• BNC connector

• RCA connector

• SMA connector

The variation in delay of received packets over time

• Latency

• Jitter

• Bandwidth

• Throughput
