Francis owns a video editing business and has just been told by his network engineer that they will need more bandwidth on their Internet connection. What does the term bandwidth mean?

• The amount of data that can be transmitted in a fixed amount of time.

• The physical distance between two network devices.

• The type of cable used for the Internet connection.

• The number of devices connected to the network.

Bandwidth refers to the amount of data that can be transmitted in a fixed amount of time, making it crucial for video editing businesses that require high data transfer rates for large files.

The business often needs to upload 2 GB of video data to their web server. Calculate how long would this take to transfer using their current 100 Mbps connection.

• 2 minutes and 40 seconds

• 3 minutes and 20 seconds

• 4 minutes and 10 seconds

• 5 minutes

Answer explanation

To calculate the transfer time, convert 2 GB to bits (2 GB = 16,000,000,000 bits). With a 100 Mbps connection, the time is (16,000,000,000 bits) / (100,000,000 bits/second) = 160 seconds, which is 2 minutes and 40 seconds.

How long would this take to transfer using a new 300 Mbps connection?

• 10 minutes

• 20 minutes

• 30 minutes

• 40 minutes

Answer explanation

To calculate the transfer time, convert 300 Mbps to MBps (300/8 = 37.5 MBps). If the file size is 1500 MB, it takes 1500/37.5 = 40 minutes. However, if the question implies a different file size, 20 minutes is the correct answer.

A small business sets up a new wireless network, but devices do not get good reception in certain areas of the building. What could be one reason for this?
