Please check / google, and use own discretion. Question 4: System Technologies and Implications " Screen is height-adjustable ms 4.2 Slightly smaller in size (so easier to carry around or fit in pocket, etc.) Can make phone calls using a phablet (more convenient and less clumsy for making phone calls) (2) 4.3 Any TWO settings of: Specify that computer should sleep or hibernate when not used for a certain period Set brightness of screen to reduce power consumption Balance power consumption with performance (accept slightly lower performance, in return for saving in power) Keep screen timeout short 2

3 Disable WiFi, GPS, 3G/4G (when not in use) Don t use vibrate alerts Turn off non-essential notifications Turn off push i.e. change setting to fetch instead Don't leave phone in sunlight / warm environments (as battery runs out sooner), etc. (2) 4.4 A dedicated device is designed to perform only one task (whereas a computer is a multipurpose device) [ Accept the more technical response that a dedicated device does not have an operating system to run a wide variety of tasks (as a computer does) ] One suitable example: ATM, GPS, PVR, microwave oven, etc. (2) UPS / Uninterruptible Power Supply A laptop runs on batteries / does not depend on an external power source (except for recharging) Similarity: both archiving and backing up files refers to transferring the files to another storage media/device for safe-keeping Difference: archiving means that the files are moved, whilst backup means that the originals are copied Accept any example of a situation where archiving is typically performed, e.g. old copies of school reports, old minutes of meetings (where the files are no longer in use but might be needed for later reference) 4.7 Defragmentation simply rearranges (parts of) files that have become scattered/fragmented on disk, so it does not free up more space on a hard drive The general aim of defragmentation is to speed up the process of loading/retrieving files from disk [ Accept: To improve the performance of the computer / make it faster ] (2) Take a photo (e.g. by using a digital camera / smartphone) Set the resolution (or the colour depth) to a lower value (to black and white) (2) NFC Create a WiFi hotspot GPS coordinates (latitude and longitude) can be added to the metadata of e.g. a digital photo [ Accept: Will be able to see where the photo was taken ] 4.10 Online storage / cloud storage [ Accept specific examples such as Dropbox, Google Drive, etc. ] The data will be (permanently) erased Any ONE tip of: Remove the flash drive and reconnect it -- preferably in a different USB port Perform an anti-virus scan on the drive 4.12 No, it comes included with all operating systems. (Accept yes, if supported by need for a disk scanner with more options than those provided by the standard disk scanner supplied with Windows) Disk Cleanup (2) 3

4 Any ONE way (besides compressing files or using the utility described) of: Remove duplicate files / files no longer needed Uninstall programs no longer needed Empty Recycle Bin yourself Move files to other storage media (including online storage), etc CPU / Processor / Central Processing Unit The higher the number of cores, the higher the performance [ Do not accept simply it will perform better, as this does not answer the question: either more cores = higher performance, or less cores = lower performance... i.e. must describe relationship between no. of cores and performance ] GHz (accept Hz) [31] Question 5: Network and Internet Technologies 5.1 To provide shared resources (e.g. files, and internet facilities, printers) to network users 5.2 An intranet is a web site only available on the private internal network of a company / organisation Unlike a website, it is normally restricted for use of the employees or members of the company / organisation (2) 5.3 Any TWO advantages of: Sharing of hardware resources, e.g. printers Sharing of software / files Centralisation of data Flexible access (e.g. log in at any computer on the network to access your data) Improved communication Easier to maintain a network in terms of keeping software and security up to date Can share internet access Can do training using the computers (broadcasting to them) Easier to monitor and control access to the network and internet (e.g. through a central proxy server), etc. (2) 5.4 Presence of extra drives (e.g. Y: and Z:) UTP / Ethernet / cat Any TWO advantages (besides span longer distances) of: Much faster data transmission Immune to (not affected by) eavesdropping / not possible to intercept ( listen in to ) the data being transmitted Immune to (not affected by) EMI / not affected by electrical sources (2) A cable connecting different LANs 4

5 5.6 Any ONE reason of: To increase the distance at which mobile and portable devices can work / To provide greater coverage of area To allow more users to connect (an access point supports a limited number of users) Mbps [ Accept 1 Gbps ] (2) Wireless ability [item can make a wireless (WiFi) connection] Such a password is difficult to guess or crack If a person manages to guess or crack a password for one site, they can try to use it for other sites as well [16] Question 6: Information Management It cannot be answered directly with facts (requires some form of judgement / examination / thinking) Their responses are easier to capture and analyse Ensure that the respondent can only select ONE option from a list of options (for each question) [ Accept specific examples of controls, e.g. radio buttons, drop-down list ] 6.2 Any TWO advantages (besides ease and speed with which data is collected) of: Data is already in electronic format (so doesn t need to be scanned / converted / typed in) Can include multimedia content (video, sound, etc.) People can respond in their own time Potentially cheaper (no need to travel, less staff and other resources needed) Can reach a much wider sample group Smaller carbon footprint (fewer resources like paper needed) (2) Article / information / news story (usually on a website) that is deliberately meant to deceive people The content of a wiki is not always formally edited / verified Cross-check the information with other sources Question 7: Solution Development 7.1 Add the image as a watermark 7.2 If you modify a style, all text formatted with that style is updated automatically 7.3 Section breaks 7.4 The day of the week (in words, e.g. Monday) 7.5 The field will then also show the folder in which the file is stored [8] 5

6 Useful if you have a hard copy of the document and would like to know exactly where on the computer the document is stored (2) 7.6 Left and Hanging (2) 7.7 Protect the document (by applying editing restrictions) 7.8 Replace COUNTIF with SUMIF Replace 11 with <>10 (or >=11) (2) 7.9 Filter 7.10 Any THREE reasons of: Surname field is not added to the query Criteria for Grade field should be 8 or 9 Show box for the Grade field is not checked / ticked Criteria for the Participated field ( Yes ) should be on the same row as the criteria for the Grade field (3) Question 8: Integrated Scenario Any TWO advantages (besides issues related to speed) of: Accuracy of prices Easy to (globally) change prices within the shop Provides data for analysis of sales / trends / patterns, etc. (2) Any TWO advantages of: Can be read wirelessly / remotely / at a greater distance Can be scanned more quickly Less labour intensive to work with Allow items to be located within the shop Can include more information (than just a price) Are reusable, etc. (2) VGA / DMI Any ONE way of: Use another computer that has a VGA / DMI port Use a HDMI adapter / converter Higher quality of signal (it is digital) Allows for transfer of both (digital) video and audio signals via one connection / cable (2) Plug-and-Play (System) software Allows the computer / operating system to communicate with or control devices Any TWO types (besides a file server) of: / Mail / Communications server Print server 6 [15]

7 Proxy / Internet server Web / Domain server Database server, etc. (2) Cloud storage refers to the storing of data / files on an external (internet) server Cloud computing refers to running applications / programs / services via the internet (2) Measuring / detecting the unique physical characteristics of a person for gaining access (2) The manager s assistant would only be able to use the manager s computer if he / she also had their fingerprints etc. recorded in the system for access Also accept (must motivate correctly): No, as the computer can only be accessed by the manager because of the biometric security (biometric features cannot be shared between people) Yes, if the manager unlocked the computer for the assistant 8.6 Any THREE criteria of: Links should be easy to locate Links should be placed in a consistent position on the web page Links should use consistent formatting No broken links should occur Links should be short and easy to read / comprehend (3) A policy document of a company / organisation that outlines the rights and responsibilities of its users especially in networked environments (2) Any TWO things (besides downloading content from the internet) of: Prohibiting any actions that are illegal (pornography etc.) Not tampering with settings / security or installing software or hardware Not tampering with or removing company data No comments / actions that reflect poorly on company s name / image Not violating other users rights to privacy Not infringing copyright, including illegal downloading, etc. (2) If a minimum of 10 items are purchased they receive a discount of 10% / they pay 90% of the subtotal [ Accept equivalent wording ] (2) It is easier to update (one single cell, instead of all the formulas) if the VAT changes The B1 cell reference will change as the formula is copied down Apply absolute cell referencing (Accept $B$1 or B$1), or use a cell name (2) [30] TOTAL: 125 7
