the effects, damages of using too much IT blah blah
Name four labour-saving devices
Cookers, freezers, microwave ovens and vacuum cleaners.
Advantages of using microprocessor-controlled labour-saving devices
People do not have to do manual tasks at home.
more time for leisure activities.
No need to stay at home while food is cooking.
Possible to control ovens or automatic washing machines with just a phone.
Disdvantages of using microprocessor-controlled labour-saving devices
Can lead to many unhealthy lifestyles.
People get lazy as they depend too much on it.
People become less fit as device carries out many manual tasks.
There is risk of hacking and cybersecurity.
Advantages of general microprocessor-controlled devices
Save energy because they are more efficient (e.g. switching themselves off after some activity. )
It is easier ‘programming’ these devices to do tasks rather than turning knobs and pressing buttons manually
Disvantages of general microprocessor-controlled devices
The device leads to a more wasteful society
More difficult to operate for people who are not very confident around these devices.
Leaving some devices on just wastes electricity.
Microprocessors used in transport systems
traffic controls on smart motorways.
air traffic control at airports.
railway signaling systems.
ANPR.
What are smart motorways?
Allows the monitoring and control of traffic. If there is any accidents they can reroute the traffic quickly.
Advantages of monitoring/control systems
Monitoring/control systems streamline tasks, making operations efficient and faster.
They provide precise, real-time information, ensuring reliability in decision-making.
By using resources better and making fewer mistakes, these systems help save money.
Users can monitor and manage operations remotely, offering flexibility and convenience.
Disadvantages of monitoring/control systems
Hackers could gain access to the computerized system and cause disruption.
If computer system fails, the whole transport system could shut down.
Poorly-designed systems could risk safety and make it inefficient.
Criminals using false number plates can easily fool the system.
Advantages of autonomous vehicles
Safer because there is less human-errors, leading to fewer accidents.
Better for the environment as vehicles operate more efficiently.
Removed traffic congestion in cities.
Reduced travel and commuting times.
Advantages of autonomous vehicles
Very expensive item to set up in the first place.
Vehicle control-system can be hacked.
Driver and passenger are hesitate towards new technology
System needs to be well-maintained anytime.
Advantages of autonomous trains
Train arrives on time.
reduced running costs as fewer staffs are required.
Improved safety as human error is removed.
Easier to change train scheduling during busier times.
Disvantages of autonomous trains
The control system can be hacked.
System doesn’t work well with very busy services.
Passenger reluctance for new technology.
High capital costs and maintenance.
Health Risk: Back and Neck strain
Causes of health risk
Sitting in front of a computer screen for long periods of time.
How to reduce it
Using fully adaptable chairs, footrests to reduce posture problems and tiltable screen.
Health Risk: Repetitive strain injury (RSI)
Causes of health risk
Damage to fingers and wrists caused by continuous use of a keyboard or repetitive clicking of mouse buttons.
How to reduce it
Take regular breaks and exercise
use ergonomic keyboards
use wrist-rest and maintain correct posture.
Health Risk: Eye strain
Causes of health risk
Staring at a computer screen for too long or having incorrect lighting.
How to reduce it
Change screens to LED.
Take regular breaks + exercise.
Exercise or test your eyes on a regular basis.
Use anti-glare screens.
Health Risk: Headaches
Causes of health risk
Incorrect lighting, screen reflections, flickering screens etc.
How to reduce it
Take regular breaks and exercise
Exercise or test your eyes on a regular basis.
Use anti-glare screens
Drink aispirin.
Health Risk: Ozone irritation
Causes of health risk
Laser printers in office. (symptoms are dry skin and respiratory problems.)
How to reduce it
Proper ventilation
Laser printers should be in a designated laser room.
Change to using inkjet printers.
What is a compressed hour?
An employee works their full hours for the week but works for fewer days. Eg: they may complete their 40 hours in four days rather than the normal five days.
What are flexible hours?
This arrangement allows the employee to organise their working schedule in an individual way. (e.g. employee might choose to start work a little later in the morning and continue to work longer, or start to leave earlier.)
