Question 2

Question 4At the moment when an item is sold at the refreshment kiosk, the item code is keyed in using a conventional keypad. During busy periods this method is too slow and queues develop. Recommend a more suitable input device. Explain how this device works.

Accepted Answer

A concept keyboard is a more suitable option to key in items at a refreshment kiosk as it will be faster.Concept keyboards provide a practical alternative to standard keyboards in scenarios requiring simplicity, ease of use, and customization. They display graphical symbols or icons representing specific functions, commands, or data inputs on a flat surface or panel.

Question 3

Question 5There are two types of memory, random access memory (RAM) and read only memory (ROM).(i) Give one use for RAM(ii) Give one use for ROM(iii) Describe the differences between RAM and ROM.

Accepted Answer

(i) RAM stores the required data and information during the processing phase.(ii) ROM stores a set of start-up instructions that tell the computer what to do when it is powered on.(iii) The differences between RAM and ROM are as follows:CategoryRAMROMFull formRandom Access MemoryRead-only memoryDefinitionRAM is a form of data storage that can be accessed randomly at any time, in any order by CPU.ROM	is also a form of data storage that generally stores hardwired instructions (instructions stored as form of circuit) for the computer to start initially.AlterationsRAM contents can be changed or altered as and when required.ROM cannot be easily altered or reprogrammed.UseRAM allows the computer to read data quickly to run applications.ROM stores the program required to initially boot the computer or reboot the computer.Operations supportedIt allows reading and writing.It only allows reading.VolatilityRAM is volatile i.e., its contents are lost when the device is powered off.It is non-volatile i.e.,	its	contents are retained even when the device is powered off.SizeLarger than ROM; can be up to some Giga Bytes (GBs)Smaller but large enough to hold basic instructions ; is up to some Mega Bytes (MBs)SpeedRAM chips can read data faster than ROM.ROM is slower as compared to RAM.

Question 4

Question 7Lorretta produces publicity leaflets for Betterview.Publicity leaflets contain articles, photographs and diagrams.Lorretta has additional hardware for producing these leaflets.This includes a colour scanner.(a) Describe how Loretta should use her computer workstation to :store a photograph as a computer file ;load the stored photograph into one of the blank boxes.(b) Lorretta needs to produce a proof colour copy of the leaflet to show to her manager. Describe two features of a printer which would be needed to produce the leaflet.

Accepted Answer

(a)Loretta should use a colour scanner to store a photograph as a computer file by following the given steps:She should place the photograph on the scanner bed and use the scanning software on the computer to initiate the scanning process.Choose the desired format and resolution for the scan.Save the scanned photograph to a specific folder on the computer's hard drive.To load the stored photograph into one of the blank boxes on the leaflet, Loretta can use desktop publishing software in the following manner:Open the software and create a new project or open the existing leaflet design.Locate the blank box where the photograph should be inserted.Use the software's "insert image" or "import image" function to browse and select the previously scanned photograph.Resize and position the photograph within the box as needed.(b) Two features of the printer which would be needed to produce the leaflet are:High-resolution printing — A high-resolution printer of minimum 300 DPI (dots per inch) is essential to produce a proof colour copy with sharp images and text.Color accuracy and calibration — To ensure the printed leaflet's colours match the digital design, Loretta needs a printer with good color accuracy and calibration.

Question 5

Question 8Give two ways in which a CD-ROM disc is different from a floppy disc.

Accepted Answer

Two ways in which a CD-ROM disc is different from a floppy disc are:Storage capacity — CD-ROMs can hold around 700 MB of data, while floppy discs typically have a storage capacity ranging from 1.44 MB (3.5-inch) to 1.2 MB (5.25-inch).Durability and reliability — Floppy discs are susceptible to physical damage, data corruption, and magnetic interference. CD-ROMs, on the other hand, use optical technology, which makes them more resistant to physical damage and offers better data integrity over time.

Question 6

Question 9A pupil is researching material for a school project. The pupil has a computer that has a CD-ROM drive and access to the Internet.(i) Give one advantage of using the Internet rather than a CD-ROM.(ii) Give one advantage of using a CD-ROM rather than the Internet.

Accepted Answer

(i) An advantage of Internet is that it provides access to a wide range of resources, including articles, research papers, multimedia content, and the latest news, allowing the pupil to access the most current and relevant information for their school project.(ii) One advantage of using a CD-ROM rather than the Internet is that it does not require an active internet connection to access the information. CD-ROMs are self-contained and can be accessed directly from the computer's CD-ROM drive, making them a reliable source of information even in areas with limited or no internet access.

Question 7

Question 10A company is developing a piece of multimedia language software for use in a school. Give two reasons why the company decides to issue the software on CD-ROM and not on floppy discs.

Accepted Answer

The company chooses CD-ROMs over floppy discs for the following reasons:Larger storage capacity — Multimedia language software typically contains a large amount of data, including audio, video, and interactive elements. CD-ROMs offer a significantly larger storage capacity compared to floppy discs.Better data transfer rate — CD-ROMs have a faster data transfer rate compared to floppy discs. This means that the software can load and access data more quickly from a CD-ROM, resulting in a smoother and more responsive user experience.

Question 8

Question 11A newspaper needs some pictures to insert onto the front page. Give three ways you can use Information Technology to obtain the pictures in electronic form.

Accepted Answer

The pictures can be obtained in electronic form using Information Technology in the following ways:Online Image Databases — They can access stock photo websites for a wide selection of pictures.Social Media & User-Generated Content — They can search for relevant images shared by users on social media platforms like Twitter, Instagram, Facebook, etc. and use them with proper permission and attribution.Digital Cameras and Smartphones — They can capture original pictures using digital cameras or smartphones.

Question 9

Question 13Give one reason why you would not edit a large movie file on a CD-ROM.

Accepted Answer

CD-ROMs are read only storage devices i.e., once data is written to the CD-ROM, it cannot be modified, edited, or deleted. Hence, editing a large movie file directly on a CD-ROM is not possible as it would restrict us from saving the changes made.
