Network Bandwidth
Network Broadband
Latency
The distance between all of the combined devices
What does bandwidth measure in a computer network?
The number of users on the network
The type of transmission media used
The speed at which data travels
The amount of data sent and received successfully in a given time
How is bandwidth commonly measured?
Bits per second
Frames per second
Packets per second
Bytes per second
Which analogy best explains bandwidth?
A computer processing data
A straw compared to a drainpipe
A car traveling on a highway
A wireless signal compared to a wired signal
What happens when too many users are on the same network?
The network slows down due to insufficient bandwidth
The network becomes more secure
The network speeds up
The network automatically upgrades bandwidth
Which type of transmission media has the highest bandwidth?
Copper cables
Fibre-optic cables
Wireless connections
Satellite connections
What is the main disadvantage of wireless connections compared to wired connections?
More expensive
Higher bandwidth
More reliable
Lower bandwidth
What does a higher error rate in a network indicate?
Improved signal quality
Increased need to resend data
Faster data transfer
More reliable connections
What affects the signal quality of wireless connections?
The type of copper used
The range from the wireless access point and environmental factors
The number of users on the network
The length of the fibre-optic cable
What determines the signal quality of copper cables?
The grade of material used and the length of the cable
The number of users on the network
The type of wireless access point
The environmental factors
What is latency in a computer network?
The delay from transmitting data to receiving it
The amount of data sent and received
The error rate in data transmission
The bandwidth of the network
What is a common cause of latency in a network?
Low error rates
Using fibre-optic cables
Bottlenecks in the network infrastructure
High bandwidth
How can latency be reduced in a network?
By increasing the number of users
By not using switches
By appropriately segmenting traffic using switches
By using copper cables instead of fibre-optic cables
What can cause hardware to contribute to latency?
Using wireless connections
Using fibre-optic cables
Using transmission media and hardware that operate at different speeds
Using high-quality switches
Which factor is NOT mentioned as affecting network performance?
Number of users
Encryption methods
Bandwidth
Error rate
What is the relationship between bandwidth and the number of users?
More users increase bandwidth
More users decrease bandwidth if insufficient
Bandwidth is unaffected by the number of users
Bandwidth automatically adjusts to the number of users
