1.6 Computer Science Flashcards
what is a stakeholder?
Anymore impacted by the actions of an organisation
What are ethics?
Moral principles that rule a persons behaviour
What are some environmental impacts of selling a game/software online rather than CD?
No plastic packaging= less landfill
Game isn’t transported via cars= less co2 emissions
Fewer factory emissions= less pollution
Few disks made for manufacturing
What is the correlation between computers and energy?
They use LOTS of energy as they are ran continuously
How can we recycle computers?
Postpone upgrading and try to reuse OR take them to e waste recycling facilities
Why are computer components such a big issue for the enviroment?
Many computer components are hard to recycle OR contain toxic material
What is E waste?
Electronic waste that can lead to release of toxic substances or loss of valuable materials i.e gold
What is the digital divide?
A division between people who can use technology and those who cannot or are uncomfortable to use it. This can be cause by … lack of money, location, e.g. rural and urban areas and lack of digital skills
What are some benefits to the use of robotics?
Safer working environment= less accidents
Faster manufacturing
Cars could ultimately become cheaper as employees wont need to be paid
What are some drawbacks to the use of robotics?
System errors could result in major defects
Mass reduction in labour skilled workers= lack of skills in a population
Discuss good impacts of getting internet access
Virtual access to family/friends
Local schools have better/worldwide resources
Businesses can be worldwide= more customers= more tourism= more online hotel bookings etc= economy profit
Discuss bad impacts of getting internet access
Digital Divide between older and youngers
People have to learn how to cope with types of malware or this could result in leaked data
Pressure to be on the internet and some families cannot afford which could lead to bullying
Illegal activities encouraged i.e. hacking or tracking
What legal issue is arising due to computers?
Computer usage for illegal activities like hacking, stealing personal data, spyware etc
What is legislation?
The process of making or enacting laws.
What are the 3 types of main legislation in CS?
The data protection act
Computer misuse act
Copyright design and patents act
What is a data protection act?
Why do data protection acts exist in the UK?
A European act/law that tightens data privacy
To ensure organisations comply with uk law about data privacy on a national scale
What are 4 data protection principles?
PD= personal data
PD must be relevant and accurate
PD must be gained for explicit / legitimate reasons
PD must not be kept for too long
PD must be handled securely and lawfully
What is the computer misuse act?
Attempts to discourage people from using computers for illegal purposes
What are 3 activities/ principles of the computer misuse act?
Its illegal to access data on a computer without permission
Its illegal to access data to be used for further illegal activities i.e. fraud
Its illegal to make changes to data on a computer without permission
What is the copyright, designs and patents act?
Protects peoples creations i.e. books
What is copyright?
A legal way for people to protect their creations. It gives copyright holders exclusive rights to publish, copy, distribute and sell their creations.
How is copyright applied?
Automatically if a criteria is met ( no need to register)
What is a licence?
When you buy something the copyright holder gives you permission to use it as part of the sale
What can you not do without permission from the copyright holder?
make copies of the material, sell or publish it, distribute it
How can we keep data secure to follow the principles of the data protection act?
Use firewalls and antiviruses and restrict data access to others as much as possible
What is plagiarism?
Passing somebody else’s work as your own- without their permission
What is open source software? Give some examples
Software that is often free of copyright and available to everybody- THE SOURCE CODE IS MADE AVAILABLE
i.e. mozilla firefox, linux, python
What are some advantages and disadvantages of open source software?
ADV- Costs nothing to the user
Gives source code so allows modifications
Many programmers can contribute to the programme
Modified versions MUST be free
DISV- can contain bugs as their are no requirements
Little online support
What is meant by proprietary software?
Copyrighted software where the source code is disclose and customers cannot modify the software
What are the advantage and disadvantages to proprietary software?
ADV- should be free of bugs
Help from organisation easily
Feature updates
DISV- subscription costs
Software cannot be modified for users
Cannot redistribute software if license doesn’t allow them to
Explain one benefit to a software developer of providing proprietary software instead of open source software.
Stops competing companies copying their
software and producing similar/better products.
Give examples of types of copyright licences:
No-derivative= William can set that if others edit it they
cannot redistribute it with the edits.
Attribution= can insist e.g. on having his name on it if referenced and he must be credited
Can insist on non-commercial use // others
cannot sell/profit from his work // personal
use only
What is the creative commons and how does it impact the way people use videos/work of others?
A public copyright licence which allows free distribution of work and other people can use/edit others work.
Other people can redistribute work.
But copyright holder can choose to restrict other people to be able to use/edit/share the videos.
Work is still copyrighted others cannot claim it as their own.
