Performance Metrics

Question 1

Bandwidth

Answer 1

The maximum capacity of a network channel to transmit data.
Represent the theoretical maximum data transfer rate

Question 2

Throughput

Answer 2

The actual data transfer rate achieved in practice. Considers factors like latency, packet loss and network congestion.

Question 3

Latency

Answer 3

the time delay between sending a data packet from the source to its arrival at the destination. Has an inverse relationship to throughput (Latency is up then throughput is down)

Question 4

Jitter

Answer 4

the variation in network latency over time causes irregular delays in data packet arrival. Affects quality of service (QoS) for real time applications

Question 5

Signal to Noise Ratio (SNR)

Answer 5

Measures the quality of a signal relative to background noise. It’s commonly used in wireless communication. Higher SNR indicates better signal quality and less interference.
