2 9713/13/O/N/16 © UCLES 2016 Scenario 1 Questions 1 and 2 Paraiso College has a large number of students who attend classes at three campuses. A large number of different courses are available covering many subject areas. The technology faculty is very well equipped and supports students who are involved in completing a number of different projects. Each student at the college is issued with a plastic card containing information stored on a magnetic stripe. This card is used to gain entry to each of the college campuses. Students at the college need to use the internet in order to find background information for their project work. A large amount of information will be available when they search the internet. The Technology department at the College has decided to produce a handbook detailing the equipment that is available for use by students. The handbook needs to be as accurate as possible because it will be used as a reference by students in the department.

Spreadsheet software is used to store details of customer accounts. A word processor is used to produce communications with customers. Other software is used to create the items (assets) for inclusion in the web pages. The data stored on Intweb’s websites needs to be secure.
