Can you describe the main parameters of service quality in computer systems?

The main quality of service (QoS) parameters in computer systems include:

• Throughput — the amount of data transmitted per unit of time.
• Latency — the time it takes for data to travel from the source to the destination.
• Jitter — variation in latency, important for streaming data.
• Packet loss — the percentage of data lost during transmission.
• Reliability — the system's ability to operate without failures.

These parameters help assess how effectively and stably a network or system operates, especially in real-time and multimedia transmission.
