Factors Affecting Network Performance Quiz

What is bandwidth?

• The type of network topology used.

• A measure of the amount of data that can transfer through a communications channel over a given period of time.

• The time it takes for a message to travel from one device to another.

• The number of devices connected to a network.

Which medium typically has the highest bandwidth?

• Business Wi-Fi

• Home Wi-Fi

• Twisted copper wire

• Fibre-optic cable

What happens when two devices on a network try to communicate simultaneously?

• A collision occurs

• The bandwidth increases

• The network topology changes

• The latency decreases

What is network latency?

• A measure of how long it takes a message to travel from one device to another across a network.

• The number of devices on a network.

• The type of network traffic.

• The amount of data that can be transferred over a network.

Which network type usually experiences higher latency?

• Fibre-optic network

• Wi-Fi network

• Hub-based network

• Switch-based network

What is the effect of having more devices on a network?

• Increased latency

• Increased chance of collisions

• All of the above

• Decreased bandwidth

Which of the following is NOT a factor affecting network performance?

• Color of the cables

• Number of devices

• Bandwidth

• Network topology

What is the typical bandwidth of home Wi-Fi?

• Up to 100 gigabits per second

• Up to 6 gigabits per second

• Up to 10 gigabits per second

• Up to 600 megabits per second

How does a switch-based network differ from a hub-based network?

• Switches are used only in Wi-Fi networks.

• Switches have higher latency than hubs.

• Switches transmit messages only to the intended recipient.

• Switches broadcast all messages to all devices.

What is a key characteristic of fibre-optic cables?

• They are more prone to collisions.

• They are only used in home networks.

• They have the lowest bandwidth.

• They carry data transmitted as light.
