12 Questions
What is the formula to calculate Propagation Delay?
Propagation Delay = Distance / Propagation speed
Define Throughput and its relationship with Bandwidth.
Throughput is almost one-fifth of the bandwidth. Throughput refers to the rate of successful message delivery over a communication channel.
How is Transmission Delay calculated?
Transmission Delay = Message size / Bandwidth (in bps)
What is the relation between Propagation Speed and Propagation Time?
Propagation time = Distance / Propagation speed
What is the dominant factor when calculating propagation and transmission time for a short message with high bandwidth?
Propagation time
For a long message with low bandwidth, what is the dominant factor when calculating propagation and transmission time?
Transmission time
How can the link between two points be conceptualized in terms of bandwidth and delay?
As a pipe, where the cross section represents the bandwidth and the length represents the delay.
What does the bandwidth-delay product define?
The number of bits that can fill the link.
What is the bandwidth of a network with 10 Mbps speed that can pass an average of 12,000 frames per minute, each carrying 10,000 bits?
Throughput of the network is 120,000,000 bps (120 Mbps).
How does the term 'bandwidth' differ when used in hertz compared to bits per second in networking?
Bandwidth in hertz refers to the range of frequencies in a composite signal or channel, while bandwidth in bits per second refers to the speed of bit transmission.
In Example 3.42, a subscriber line has a bandwidth of 4 kHz for voice or data. How much data can be transmitted using a sophisticated modem?
Data transmission of up to 56,000 bps is possible with a sophisticated modem.
What happens to the data transmission rate if the telephone company increases the bandwidth of the line from 4 kHz to 8 kHz?
With an increased bandwidth of 8 kHz, data transmission can reach 112,000 bps using the same technology.
Learn how to calculate throughput based on bandwidth, and understand the concepts of propagation speed and transmission speed in data communication. Explore how propagation delay and transmission delay are calculated based on distance and speed.
