ICT APPLICATIONS Flashcards
Uses of Websites
Collection of webpages, text, graphics, video, and sound
Hosted on a web server on the internet
Need to write code or use a web authoring application
Hyperlinks to other pages can be added
Interactive websites require programming knowledge
Can use a camera, scanner, and microphone to input data
Usually, hire space from the web hosting company
Advantages of Websites
Ability to add sound/video/animation
Links to other websites/hyperlinks
The use of hot spots
Buttons to navigate/move around the website
Hit counters to see who has visited the websites
worldwide advertising capability
Disadvantages of Websites
Can be hacked and modified, or viruses introduced
Need for a computer and internet connection
Lack of portability compared with the paper-based system
Need to maintain the website once it is set up
Define Multimedia Presentations
Uses a mixture of media to present information: animations, video, sound, transitions, hyperlinks
Produced using software packages
Used with a projector so a large audience can view
Advantages of Multi media presentations
Use of sound and animation/video effects
Interactive/hyperlinks built into presentations
More likely to hold the audience’s attention
Disadvantages of Mutli Media Presentations
Need for special equipment – expensive
It may require internet access
Distracts the audience from the sole content of the presentation
It is very easy to make a presentation with too many features
Define Media Streaming
Real-time transition of audio and video files over the internet
allows users to access content without downloading it to their devices
popular services include Spotify, YouTube, and social media websites
uses buffering, which makes sure the video plays back smoothly without freezing. While the buffer receives data packets, it sends previously received ones to the playback device so that there are no gaps in the played data
Advantages of Media Streaming
Users can access any information at any time and from any location
Offers an extensive library of content
Compared to traditional cable or satellite TV subscriptions, media streaming can be more cost-effective
Disadvantages of Media Streaming
Heavily relies on a stable and high-speed internet connection.
Not all content is available on every streaming platform due to licensing agreements and exclusivity deals.
You don’t own the media when streaming media, so if the streaming service removes a movie or a TV show from its library, it may no longer be accessible to you.
Advantages of Using Models
using models is less expensive than having to build the real thing
safer to use a computer model
allows you to try out various different scenarios in advance
nearly impossible to try out some tasks in advance in real life due to high risk
faster to use a computer model than to do the real thing
Disadvantages of Using Models
a model can’t be completely reliant as the output is entirely based on the input
frequently, computer modelling can be a very costly option
human reluctance is a common problem in this technology
Describe Personal Finance In Modelling
Computer modelling involves using mathematical algorithms and data analysis to simulate various financial scenarios, such as investment strategies, retirement planning, and risk assessment, aiding individuals in making informed decisions and optimizing their financial goals.
Describe the Uses of Modelling in Bridge and Build Design
Computer modelling is crucial in bridge and building design. It allows engineers to simulate and analyze structural behaviour, assess load capacities, and predict the response to external forces. It aids in optimizing designs, ensuring structural integrity, and minimizing potential risks before construction begins.
Describe the uses of Modelling in Flood Water Management
Computer modelling plays a vital role in flood water management by simulating water flow behaviour, predicting flood extents, and assessing potential flood risks. It helps design and optimise flood mitigation measures, such as levees and floodplain zoning, allowing authorities to make informed decisions, develop effective emergency response plans, and minimize the impact of flooding on communities.
Describe the uses of Modelling in Traffic Management
Computer modelling simulates and analyses traffic flow, predicts congestion patterns, and optimises traffic control strategies. It aids in designing efficient road networks, optimizing signal timings, and evaluating the impact of transportation infrastructure projects. This enables authorities to make informed decisions, alleviate congestion, and improve overall traffic efficiency for better urban mobility.
Describe the uses of modelling in Weather and Forecasting
Computer modelling plays a pivotal role in weather forecasting by simulating the Earth’s atmosphere, oceanic conditions, and other environmental factors. These models use complex algorithms to predict weather patterns, including temperature, precipitation, wind speed, and storm systems. By assimilating real-time data, computer models provide forecasts that aid meteorologists in predicting weather conditions, issuing warnings, and helping society prepare for potential hazards.
Advantages of using computer modelling rather than humans
It can provide more precise and accurate results than human-based methods, minimizing errors and increasing reliability.
Can analyze large amounts of data and perform complex calculations faster than humans
It can be reused and updated easily, reducing the need for repetitive manual analysis and potentially lowering costs in the long run.
Disadvantages of using computer modelling rather than humans:
It may overlook nuanced factors or intangible elements that humans can consider, leading to potential gaps or inaccuracies in the analysis.
Based on assumptions and simplifications, introducing a level of uncertainty.
Their programmed algorithms and data inputs bind models. They may struggle to adapt to unforeseen circumstances or rapidly changing conditions that humans can more readily navigate and respond to.
Describe the uses of Computer Controlled Systems using robots for Manufacturing
involves using automated machines to perform tasks such as assembly, welding, and packaging. These robots are designed to mimic human actions with precision and speed, increasing productivity and quality control. They offer benefits like enhanced worker safety, improved efficiency, and the ability to handle repetitive tasks, revolutionizing the manufacturing industry.
Advantages of Robots Manufacturing
can work in environments that may be harmful to humans
can work non-stop
low running costs, majorly due to reduced employees; thus less wages need to be given
have higher productivity
provide greater consistency
can do long, boring, tedious tasks
can carry out different tasks by fitting them with different-end effectors
Disadvantages of Robots Manufacturing
robots find it difficult to do unusual tasks
can cause higher unemployment
robots do many of the tasks once done by humans, leading to deskilling
robots are independent of the skills base; factory headquarters can be moved internationally
initial set-up and maintenance of robots can be expensive
Describe the uses of computer controlled systems in production line control
Computer-controlled systems in production line control involve using computers and software to monitor, coordinate, and optimize manufacturing processes. These systems ensure efficient coordination of machinery, manage inventory, track production metrics, and automate tasks. They enable real-time data analysis, error detection, and adjustment, improving productivity, reducing downtime, and enhancing overall operational efficiency in the production line.
Advantages of using computer-controlled systems rather than humans
increased efficiency and productivity
greater consistency
ability to work in any environment
reduced human error
can work with large or delicate items
Disadvantages of using computer-controlled systems rather than humans
very high instalment costs
very high maintenance costs
dependency on reliable
lack of flexibility
requires costly backup systems
