2 © UCLES 2012 9713/11/O/N/12 For Examiner's Use Scenario 1 Questions 1 and 2 The North India Motor Company is a manufacturer of cars and vans. It has a modern factory and a computerised production line in New Delhi. Robot arms are used in the manufacture of each car. When Gurdeep, the programmer, programs the robot arm she does not use a remote control to guide the arm. She guides it herself manually. The company had some bad publicity recently when it had to recall a number of vehicles because of a problem with the brakes. Venkhat, the marketing manager, is keen to improve the company’s image but he is limited in the amount of money he can spend on such a campaign because of the cost of the recall programme. Venkhat particularly feels that the company needs to improve its image within New Delhi itself and so has ruled out the use of a website.

6 © UCLES 2012 9713/11/O/N/12 For Examiner's Use Scenario 2 Questions 3 and 4 Redcar Professional Assessment is an examination board. It uses an ICT system to have examination papers marked online. Examiners use their PCs at home to mark the examination papers. The board would like the reports and certificates produced by the system to be updated and better presented. Subject specialists at the board’s three regional offices analyse results and deal with candidate queries. They find the current system difficult to use and need a system that can provide fast and easy access to candidate results. The board has employed Malcolm, a systems analyst, to develop a new system for storing and analysing results. He has been asked not to look at the marking of examination papers as the board is satisfied that this part of the system works very well. He has already researched the existing system for storing and analysing results. He has recorded the information using data flow diagrams. The board is aware that new examiners will need to be trained so that they can mark online. These examiners might have difficulties getting to a central venue, so the board has decided to use video conferencing for this training. Each new examiner will be expected to use their own PC including a monitor, mouse and keyboard. Other hardware will be provided by the board if necessary.

CAMBRIDGE INTERNATIONAL EXAMINATIONS GCE Advanced Subsidiary Level and GCE Advanced Level MARK SCHEME for the October/November 2012 series 9713 APPLIED INFORMATION AND COMMUNICATION TECHNOLOGY 9713/11 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 should be read in conjunction with the question paper and the Principal Examiner Report for Teachers. Cambridge will not enter into discussions about these mark schemes. Cambridge is publishing the mark schemes for the October/November 2012 series for most IGCSE, GCE Advanced Level and Advanced Subsidiary Level components and some Ordinary Level components.

Can choose to work off peak hours as travelling to work outside peak times is easier and cheaper If technicians stay late to finish a job, they can take time off at a later date If the job requires great concentration, it can be done at quiet times of day.
