21.
a) Issues aren't questions, although questions can be reworded so that it isn't phrased as a question.
b) Didn't explain the interaction between the components.
Collect competitor details manually with a form, then entered into computer. Competitors may also register online (go onto website, use information technology). Timing devices & timing mats collect times; that data then transformed into information, results displayed on website.
d) Didn't do
Collecting - the system is designed to get accurate times - quantitative record
Analysing - graphs & charts, calculations, identify patterns & trends (can see progress in performance)
Storing & Retrieving - can access the data at later date, maintain records over long time
Displaying - the results are shown on the website, people can get useful information
 
22.
c) Need multimedia software - my answer focused more on the coding side of the website & not the content.
Graphics package - manipulate images
Word processing - articles
Relevant software for video & audio
 
23.
a) Need to be more specific about the problems with the issues
Misuse & abuse - can quickly collect information (can collect lots of different types of data, such as images, audio,& convenient Internet access means that this information can quickly be spread around)
Cause strain - screen is too small (eye strain), keys are quite close together
& newspapers are portable.
b) i) Author was the entity, not the way they got data into the system
   ii) Have to talk about the relationships between the issues
Virtual communities with members from all over the world
- people can meet more people, humanitarian efforts
- terrorists
Information can be spread further more quickly
- people become more aware of things happening around the world, share information & knowledge
- privacy can be invaded & confidential information can be spread around very quickly
New technologies spreading more information about the world
- more competition leads to higher quality service
- problems with data integrity
c) Have to be more specific about the issues - my answer did not go into the details of each aspect
Technical
- increased volume of traffic
- student demands will increase - consider scalability & future development
Economic
- quality & specifications of hardware
- hiring technicians, technical support officers
- look at things over long term
- need powerful data & network server
- hardware & software infrastructure
Staff
- more IT staff
- academic staff shouldn't have to deal with too many changes
- IT staff need to be on site, may need more personnel
Other
- occupational health & safety - radiation
- filtering & censorship
 
24.
a) ii) The system is semi-structured
   iii) Answer was too generalised - need to relate to the situation.
Inputs quite certain - need the position of head (eyes, ears), blinking patterns. May not have relevant data, or the data is difficult to analyse
Criteria quite certain - the system knows how to make a decision based on the input
Outputs - as long as the input is there, it knows what output to give depending on the rules
b) Didn't do
Potential misuse - spying, invasion of privacy, false alarms, unfair dismissal
Responsibility - system designers, programmers, testers, researchers, system not being calibrated
Changing nature of technology - cost of system, training drivers, lives depending on technology
 
25.
a) i) Need to relate to how 20Q would actually work in order to guess the object.
System learns by asking questions, confirm knowledge by asking questions. Players may answer differently, & system can weigh responses. Can choose most probable responses based on patterns. Parallel processing is used.
   ii) Answer was generally about neural networks, but should relate to how this particular system would work.
Randomly generate questions, gather answers to analyse trends & determine probable answers, incoporate into knowledge base. Ask questions that allow it to distinguish between similar objects.
 
 
26.
a) Mobile phones & international phone calls are two types of technologies.
Internet access, mobile phones, international phone calls
b) Should make a distinction between alleged & confirmed uses, & should read article more carefully
Alleged - organisation of riots, co-ordinating, false rumours afterwards
Confirmed - blame on Muslim Uyghurs, spreading updates, daily updates & weather reports after riots
c) Needed a range of aspects - did not have enough
Severity of violence, significance of information & information systems, ease of quick response, disrupting, proximity, reliance on technology
d) Should relate to issues in the scenario
Prevent outside help coming in,
e) Didn't do
 
Marks lost:
Project Management: 2/11
Information systems: 5/10
Databases: 3/9 (excludes Q6)
Communication Systems: 17/36
Multimedia Systems: 5/26
Decision Support Systems: 14/32
 
Things to work on: issues, being more specific, interaction/relationship between various parts of the question, eliminate colloquial bits from answers. I also need much better time management.
