6.3 The games administrator wants to archive files on the server to free up disk space.

6.3.1 Explain what is meant by archiving files.

6.3.2 Will more disk space be saved if archived files are moved from a physical server to a virtual server? Motivate your answer.

6.4 At a previous gaming event gamers complained that too much bandwidth was used while streaming games.

6.4.1 For the current gaming event gamers were informed that they can configure the settings on their computers to optimise game play. Explain what can be done to save bandwidth while streaming.

6.4.2 The gamers want to restrict the websites that can be accessed in order to reduce network traffic. Explain how a firewall could be used for this purpose.

6.4.3 Why is it usually quicker to use BitTorrent protocol to download a file rather than downloading the file directly from a server?

6.4.4 Someone mentioned that BitTorrent should be avoided as it is illegal to use. Is this statement true? Motivate your answer.

6.6 Separate versions of some of the gaming software applications have been developed to provide for different operating systems, such as Android and IOS.

6.6.1 Motivate why the same application needs to be programmed differently for different operating systems.

6.6.2 An important feature of an operating system is backward compatibility. Use an example to explain the concept of backward compatibility.

6.7 During an interview with the author of one of the games, the response to a question on the features of a successful online game was as follows:
"Scalability, fast response time, security and low cost to get in."

6.7.1 Why is scalability important when designing online games?

6.7.2 Why will security be a challenge for a peer-to-peer network?

6.8 The "app-ification" of the Web has seen many well-known websites becoming applications that run on mobile devices.

6.8.1 Briefly explain what an app is.

6.8.2 Give TWO reasons why gamers wanting to register for the gaming event might prefer to use an app instead of the website.

6.9 One of the gamers will use the headset in the illustration below.

Many of these types of devices contain firmware. Explain what firmware is.

(a) The headset supports plug-ins. Explain what a plug-in is.

(b) How does the fact that the headset supports plug-ins benefit the gamer?

These types of devices normally contain sensors. Name TWO possible types of sensors found on gaming devices.
