We have seen more and more news stories of hacking and computer viruses that has affected business’ heavily. We’ve also all seen stories of copyright piracy and it’s impact on the tv, film and music industry.
There have also been a lot of concerns over the impact of these systems on our health and our environment.
In this lesson we will learn about the issues relating to:
The use of technology systems has raised a number of health & safety concerns that users of ICT systems must be aware of to ensure they are not affected. A number of laws have been passed to ensure business’ take the health & safety of ICT users seriously.
Some of the issues include:
Look at how you are sat at your computer. Is the top of the monitor at eye level? Is your face around 18 inches from the screen? Are you sat with a straight back? All these should be true if you don’t want to hurt yourself.
Also, look around you. Are there any loose cables around you that you could trip over? What could you do, or is being done, to prevent any trip hazards?
Technology systems, especially those connected to the internet, are potentially at risk from security threats. These security threats are normally caused by malicious users who want to gain information from a computer in order to profit from it financially.
There have been laws put in place to help reduce these threats, but they still exist and are a major cause for concern.
Example security issues include:
Have you ever been affected by a virus or other malicious software?~
Research online about some of the best-known cases of viruses and hacking that have affected businesses.
In many ways, technology systems have had a positive impact on the environment. The internet has reduced the need for travelling, which can reduce the number of greenhouse gases being released due to fewer cars on the road and planes in the air. It has also led to less need for paper as documents can be stored on a computer and sent to other people via the internet.
However, there are environmental issues relating to the use of technology systems. Examples include:
How much technotrash do you personally produce each year? Think of any computing devices you have discarded, such as an old phone or computer.
Research how much technotrash is produced each year, and it’s impacts on the environment.
There has been a lot of concern over how much data is being shared by technology systems, such as over the internet. In particular, the amount of private information we share online and the illegal distribution of copyrighted tv, film & music.
These issues are a huge concern with the use of technology systems. For example:
How much of your personal information do you share online? Have you ever thought about the dangers of doing so?
Research stories about people’s personal information being stolen online and the impact it has had on them.
Malware – small programs that are designed to attack computer systems such as viruses, spyware, worms & trojans.
Anti-Virus – a program that is designed to prevent viruses and other malware from infecting your computer before they can cause damage.
Firewall – a program that monitors all data being transferred to and from a computer system and closing down any connections that it thinks might be harmful.
Sustainability – in the context of the environment this is the use of environmental resources in a way that does not damage and deplete them and so allows for long term environmental quality.
Encryption – the process of turning data into another form, called ciphertext, that cannot be understood without being decrypted.
So to summarise what we’ve learnt in this lesson:
