Fundamentals of Computer Network Performance Quiz

Transit Time in Computer Networks

• Transit time refers to the duration it takes for data packets to travel from the source to the destination across a network.
• Factors influencing transit time include propagation delay, transmission delay, and queuing delay.
• Propagation delay is the time it takes for the signal to propagate through the transmission medium.
• Transmission delay is the time required to push all packet bits into the wire.

Reliability of a Computer Network

• Reliability is assessed based on the network's ability to consistently perform its intended functions without failure.
• Metrics used to measure reliability include uptime percentage and mean time between failures (MTBF).
• A reliable network minimizes packet loss, maintains connectivity, and recovers quickly from failures.

Security in Computer Networks

• Security encompasses measures and protocols designed to protect data integrity, confidentiality, and availability.
• Key components of network security include firewalls, encryption, and authentication mechanisms.
• Common threats to security include unauthorized access, data breaches, and denial-of-service attacks.

Performance in Computer Networks

• Performance includes metrics such as bandwidth, throughput, latency, and jitter.
• Bandwidth denotes the maximum data transfer capacity of a network link, while throughput measures actual data transfer rates.
• Latency is the time delay between a request and its fulfillment, while jitter refers to variability in packet arrival times.

Response Time in Computer Networks

• Response time is the total duration taken for a system to respond to a user's request.
• It combines transit time, processing time, and queuing delays experienced during data transmission and processing.
• Short response times are critical for maintaining a good user experience in network applications.
