Explain how the movement of valuable assets in transit at sea or land can be constantly tracked.30/11/2022 Explain how the movement of valuable assets in transit at sea or land can be constantly tracked.The assets can be fitted with specialised geographical positioning systems (GPS) which keep on sending the location (longitude, latitude) of the assets to satellites.
The information can then be plotted on geographical information system (GIS) digital maps to know the exact location of assets at any time.

State various uses of computers at home.
Explain how ICT is used to control air traffic.The control tower in airports has computers that show all the aeroplanes entering a country's airspace. The air traffic controllers direct the paths of landing and taking off aeroplanes in the airport to avoid collision. Define the term 'online airline reservation system' and state its advantages.This is a special application software, usually web based, that enables travellers to book and pay for seats on planes in real time from the comfort of their homes or office. Their advantages include:
Cities and major towns experience traffic jams during rush hours. Explain how ICT can be utilised to decongest the traffic on such roads.Each vehicle can be fitted with a navigation unit and GIS/GPS/ mapping technology used to track which roads have heavy traffic and the ones that are free. This would help the drivers to select less busy routes hence save time and fuel.
. The traffic lights can be monitored using a computerised system that regulates traffic based on the intensity of traffic on each road in a junction or roundabout. List five application areas of ICT in transportation.
Kwamboka has just completed Form Four. In school, she discovered that she had a talent in singing and became an active choir member. In a move to venture into music, she bought a new PC a week ago to use it as her recording production tool.(a) Identify what Kwamboka requires to make the PC a multimedia.Multimedia applications require a high speed computer with sufficient memory, CD/DVD drive, sound card, speakers, a microphone, a Musical Instruments Digital Interface (MIDI) port, USB or firewire port, high resolution VGA and multimedia support software such as media player, MP3 and DVD player. (b) Outline the steps you would follow to configure the PC to become a multimedia system.
Differentiate between 2-D and 3-D computer games.
Highlight four achievements in the music and video production industry that are as a result of using ICT.Recording, synthesising and editing of music and video using computers is more efficient and cost effective. Music and video is more easily and cheaply stored digitally on DVDs, VCDs, flash memories and hard disks.
It is easier to download online audio and video clips. Additional sound and visual effects of music and video on the internet gives artists a wide market. Explain how computers have made local and international music and movies cheaper hence more accessible to users. Computers have made it possible to digitise music both audio and video, package and distribute it in CDs/DVDs, and to download online audio and video clips (for example, through Youtube).
The production cost has also gone down hence the sale prices have drastically come down. Some computer games are important in schools and homes. Using an example, justify this statement.30/11/2022 Some computer games are important in schools and homes. Using an example, justify this statement.Computer games provide the users with an interface that allows them to interact with various challenges that require solving on the computer screen; hence, they develop the ability to tackle real life challenges.
For example, test drive games may help one to learn how to drive a real vehicle faster and safely by enabling him/her to practise adherence to driving and road use rules and regulations. Discuss the importance of computers in the following areas of science and research. |
