The document discusses a study conducted for a retirement village website. It explains that a control group of younger people was necessary to compare to the elderly group and identify differences in computer literacy and task completion. Two key conclusions are that the website needs simple, clear instructions due to lower computer literacy in the elderly, and that an additional task of email usage could evaluate this skill and ensure residents can receive updates.

Question 1 (5 marks) A multimedia web authoring business has asked you to investigate and compare the operating systems of MS Windows and MacOS as they are currently considering upgrading their current computers systems. Evaluate the strengths and weaknesses of both operating systems in relation to its intended use and make a recommendation based upon your findings I would recommend the use of Mac due to it being a more reliable operating system as compared to Microsoft windows. With the Ms Windows constantly having bugs and problems with security it is not suited keeping the website data safe which is highly important for the web authoring business. With the Mac having a strong firewall it eliminates the need for another firewall as is required in windows. Another benefit of using the Mac is that all features are included where ms vista has four different types each coming with different features. Windows however does have a greater range of other applications and due to the wide range of use is compatible. Mac overall performs better then Ms with the lower requirement of specifications and better reliability and features. Type = Short Answer Target = 80-100 words Question 2 (8 marks) A research company has been contracted by a retirement village to conduct a study in preparation for creating a website for its residents and potential clients. An excerpt from the study is provided below.
(a) Explain why the control group is necessary in a study of this nature. (1 mark) A control group is required in the study to see how much difference there is between the elderly and younger age group. Without having the control group then you are unable to compare the differences between the age (b) The research company is preparing to present a report for the retirement village on its findings. What two significant conclusions can be drawn about possible features that the retirement village should include on their website? Explain the reasons for your conclusions. (3 marks) The older generation are less computer literate then the younger generation. This leads to the high number of errors that occurred when they were performing the task and also the longer amount of time taken to perform the tasks. Therefore the site will need to be simple with clear easy to find instructions. This lack of computer literacy is due to the lack of computers that the older generation have had as compared to the younger generations.
(c) Review the four tasks, which were performed by the two groups. Suggest an additional task that the two groups could perform in order to improve the information that the research company would provide to the retirement village. Explain what your task is designed to evaluate and give your reasons as to why it may be relevant. (4 marks) An additional task that the groups could complete is email usage. The groups should be able to login to an email account, open an email and compose a new email. This is relevant as newsletters and updated information may be sent to the residents of the retirement village and so they need to ensure that most can receive the updated information. Question 3 SA Surf Life Saving is conducting its annual National Carnival at Scarborough Beach. There will be four main event areas. Each event area will consist of a competition tent manned by surf life saving officials and judges. The event areas are: 1: Swimming. Competition tent 2: Beach events. Competition tent 3: Rescue boards. Competition tent 4: Surf boats. The National Carnival has over 18,000 entrants. The carnival will cover an area of 1 kilometre of beach near the Surf Life Saving clubrooms. The carnival will run for 2 weeks. The results from the competition tents need to be sent as quickly as possible to the clubrooms so that the carnival officials can update the result sheets. These updated results sheets are required at subsequent events, such as finals. Results are gathered every day from pda's and laptops via wired and wireless networks. The data is stored on a central database at the clubrooms Describe the processes and procedures that should be used by surf life saving officials, judges and carnival organisers to minimise possible threats to the integrity and security of the data? (5 marks) To maintain the security of the data there should be restricted access to certain parts of the database with the use of passwords and usernames. This will be important in the results area to ensure that competitors can not alter the results and the competitor’s information will need to be kept secure to ensure that it cannot be stolen and problems such as identity theft cannot occur. Virus scanners and firewalls will also need to be in
place to prevent intrusions. The wireless network will also need to be secured and only let in those with a username and password. They also need to ensure that the weather conditions don’t affect the equipment which could cause a loss of data. If problems do occur to minimise the risk of data loss regular backups is recommended. It is important to ensure that the data integrity (accuracy) is maintained. This can be done by having validation rules place on the entries. For example for the phone number no more than 10 characters and only accept numbers.
