3.1.8 - Explain why the speed of data transmission across a network can vary.

Question 1

What factors affect the speed of data transmission across a network?

Answer 1

The speed of data transmission can be affected by factors such as bandwidth, bit rate, number of users, volume of traffic, and hardware limitations.

Question 2

How does bandwidth affect network performance?

Answer 2

Bandwidth is the maximum amount of data that can pass through the transmission medium per second. Higher bandwidth allows for more data to be transmitted, improving network speed.

Question 3

What is bit rate, and how does it influence data transmission speed?

Answer 3

Bit rate refers to how fast data can travel, measured in bits per second. A higher bit rate means faster data transmission.

Question 4

How does the number of users impact network speed?

Answer 4

As more users join the network, the available bandwidth is divided among devices, leading to slower data transmission for each device.

Question 5

How does the volume of traffic affect network performance?

Answer 5

More traffic increases the likelihood of data collisions and slows down data transfer on individual connections.

Question 6

What hardware limitations can affect data transmission speed?

Answer 6

Hardware limitations, such as routing too much traffic through a single point, can cause congestion and bottlenecks. Adding more switches and routers can help mitigate this.
