Question 1 Report
Fig. 1 shows the equipment chosen for a wildlife charity's field office. The office has a desktop computer, two laptops and a network-attached storage device containing camera-trap data. A router connects the local area network to a broadband line. A wireless extender is placed near a wooden cabin where the signal from the router is weak. The charity needs staff to access the stored data, while only authorised staff should use the internet connection.
(a) Which device stores the camera-trap data for access by several computers? [1]
(b) State the purpose of the wireless extender. [1]
(c) Describe how a staff laptop in the cabin can access the stored camera-trap data. [2]
(d) Give two reasons why staff accounts should require passwords before accessing the network storage. [2]
(e) Explain one difference between access to network storage and access to an online cloud storage service if the broadband line fails. [2]
Answer Details
(a) The network-attached storage device, or network storage, stores the camera-trap data for several computers. [1]
(b) The wireless extender extends or boosts the wireless coverage range. [1]
(c) The cabin laptop connects wirelessly to the extender. The extender connects through the router and LAN to the network storage, allowing permitted files to be accessed. [2]
(d) Password-protected staff accounts prevent unauthorised people viewing confidential wildlife data and help prevent files being changed or deleted. They can also identify the user accessing data. [2]
(e) If broadband fails, network storage on the LAN can still be accessed locally. An online cloud service requires the internet connection, so it cannot be reached while the line has failed. [2]
