Network service quality is determined by several key metrics. Below is an analysis of each option:
Bandwidth : Bandwidth measures the maximum data transfer rate of a network link, expressed in bits per second (bit/s). It represents the capacity of the link to transmit data between two nodes.
Latency : Latency is the time it takes for a packet to travel from the source to the destination. Lower latency improves real-time communication and application performance.
Packet loss rate : This metric indicates the percentage of packets that fail to reach their destination due to network congestion, errors, or other issues. High packet loss degrades user experience.
Jitter : Jitter refers to variations in packet arrival times, which can disrupt real-time applications like voice and video. Consistent latency is critical for smooth performance.
All four options are correct and accurately describe key aspects of network service quality.
