2 © UCLES 2012 9713/13/M/J/12 For Examiner's Use Scenario 1 Questions 1 and 2 Oslo Banking is a large banking organisation which offers its customers loans, mortgages and insurance as well as managing their accounts. The organisation also uses an online banking system which lets customers access their account through the internet. The personal data of the customers are kept on the bank’s central computer. The bank uses a variety of security methods to prevent hackers from accessing the data either directly or by phishing or pharming. In addition, the bank needs to take steps to safeguard the privacy of customer data. The bank is currently undertaking a large advertising campaign to boost the image of the organisation. It has decided to use multimedia presentations in shopping malls to do this.

5 © UCLES 2012 9713/13/M/J/12 [Turn over For Examiner's Use 2 (a) There are three types of advertising: business, product and service advertising. Name and describe the type of advertising that Oslo Banking will use. Name Description [2] (b) Describe, with reference to the scenario, four features which are found in multimedia presentations which would not be found in a hardcopy magazine. 1 2 3 4 [4]

7 © UCLES 2012 9713/13/M/J/12 [Turn over For Examiner's Use Scenario 2 Questions 3, 4, 5 and 6 The University of Tawara Beach (UTB) is going to have a number of purpose built computer suites which will all be networked together. This will encourage the use of ICT in teaching and learning. Sean Jones, a systems analyst, has been employed by UTB to develop the new system. He has already completed the Analysis phase and collected information from teachers about what they would like the system to do. Some teachers want a system which they can use in their existing lessons. They would still be in total control of the learning. Others would prefer a system whereby the teacher just supervises the students and the computer takes over the whole learning process. Sean will need to specify the required software and additional hardware for the system allowing for the possibility that both approaches to teaching will be used. He is assuming that basic PCs will be provided with a monitor, keyboard and mouse. Sean will need to design documentation to show the teachers how to use the system. The rooms will all need to have air conditioning systems as Tawara has a very warm climate.

Jasvir, the manager of the payroll section has decided that the current payroll system is out of date and has employed Moira, a systems analyst to investigate the current system and develop a new one. The existing computer system produces payslips but no other output. Jasvir has told Moira about the need for detailed financial reports and exception reports to be produced, in addition to the payslips.

UNIVERSITY OF CAMBRIDGE INTERNATIONAL EXAMINATIONS GCE Advanced Subsidiary Level and GCE Advanced Level MARK SCHEME for the May/June 2012 question paper for the guidance of teachers 9713 APPLIED INFORMATION AND COMMUNICATION TECHNOLOGY 9713/13 Paper 1 (Written A), maximum raw mark 80 This mark scheme is published as an aid to teachers and candidates, to indicate the requirements of the examination. It shows the basis on which Examiners were instructed to award marks. It does not indicate the details of the discussions that took place at an Examiners’ meeting before marking began, which would have considered the acceptability of alternative answers. Mark schemes must be read in conjunction with the question papers and the report on the examination. • Cambridge will not enter into discussions or correspondence in connection with these mark schemes. Cambridge is publishing the mark schemes for the May/June 2012 question papers for most IGCSE, GCE Advanced Level and Advanced Subsidiary Level syllabuses and some Ordinary Level syllabuses.

Save costs of printing/sending statements Lower running costs, fewer branches so less electricity, heating and lighting.

Less money is spent on security staff [3] (c) Three from: Initially high redundancy payments Initial cost of setting up system will be high Running costs will be high due to paying website developers May lose customers who prefer face to face banking/whose internet speed is too slow to be viable/who may be worried about hacking Harder to sell other services since there is a less personal service Increased interception of data by hackers leading to fraud Some staff will need to retrain which is costly/time consuming [3] (d) Four from: Abiding by data protection rules Workers must not share any customer data with anybody outside the organisation. Workers should sign a confidentiality agreement Employees should have a duty of fidelity Information about an individual should not be passed from one organisation to another without permission of the individual Information should be anonymised where possible Information should be aggregated where possible [4] 2 (a) Matching pairs from Business advertising [1] Advertises the whole company to make the company name familiar not just a single product or service.

The valve is controlled by microprocessor to reduce/increase the flow of refrigerant Microprocessor compares the pressure of the refrigerant to the preset value If pressure of refrigerant is above preset value microprocessor opens valve wider If pressure of refrigerant is below preset value microprocessor makes valve opening narrower The required temperature is input Microprocessor compares the temperature of the room to the preset value If temperature of the room is above the pre-set value the fans remain on/are switched on by the microprocessor or microprocessor increases their speed If temperature of the room is below the pre-set value the fans remain/switched off by the microprocessor [5] 7 (a) Kerning is the process of adjusting the space between individual letters in words [1] Leading is the space between lines on a page [1] (b) Three from: They need to be compatible with the size/type of font in the headings/headlines Font type needs to be easy to read Font size needs to be small enough for stories to fit on a page Font size needs to be large enough to read [3] 8 Four from: Time is not wasted travelling/ more free time because of less travelling Can spend more time with their family/can arrange their work schedule to suit themselves Don’t have to live close to the company so can live in area of their choice Don’t have to spend money on fuel/transport travelling to work Don’t have the stress of travelling to work in rush hour If the journalist is disabled it’s easier for him/her as he/she doesn’t have to travel [4] 9 (a) Two from: an employee earning an unusually large amount of money an employee who has been on an emergency tax code for a long period of time two employees having the same National Insurance number [2]
