World of Computer Networking Your CCNA start - Summary on Network Properties

The video tutorial covers essential network parameters: bandwidth, throughput, latency, RTT, and jitter. Bandwidth is a physical layer property measured in bits per second, while throughput is the actual data transfer rate, usually less than bandwidth. Latency involves various delays, and RTT measures the time for data to travel to a point and back. Jitter describes variations in latency, affecting application performance. The tutorial concludes with a transition to discussing Ethernet.

What is the primary unit of measurement for bandwidth?

• Packets per second

• Frames per second

• Bytes per second

• Bits per second

How does throughput generally compare to bandwidth?

• Throughput is unrelated to bandwidth

• Throughput is usually less than bandwidth

• Throughput is equal to bandwidth

• Throughput is always higher than bandwidth

Which of the following is NOT a type of delay contributing to latency?

• Queuing delay

• Propagation delay

• Processing delay

• Bandwidth delay

What does RTT measure in a network?

• The time for data to be queued

• The time for data to be processed

• The time for data to travel round trip

• The time for data to travel one way

What is a potential consequence of high jitter in a network?

• Reduced throughput

• Improved latency

• Increased bandwidth

• Application performance issues
