3. Effects of ICT Flashcards
What is a microprocessor?
an integrated circuit that contains a
CPU
responsible for executing instructions
dis of microprocessors in devices
open to cybercriminal activity
Microprocessors are used in a home to monitor and control devices such as:
Central heating systems
Security alarm systems
Home entertainment system etc.
The use of microprocessors in the home can have a positive and negative impact on:
Lifestyle
Leisure
Physical fitness
dis and adv on lifestyle
Less manual tasks
Devices can be controlled outside of the home (e.g. turn on the heating on the way home)
Live security alerts sent straight to a smartphone or computer
Less manual tasks can lead to unhealthy lifestyle
dis and adv on leisure
More time to do other things
Connected activities (e.g. fitness trackers can connect with friends for virtual competition
Integrated entertainment (e.g. Smart TV offer voice control and personalisation)
Users can become tech dependant and put limits on creativity
dis and adv on physical activity
Loss of fitness due to lack of manual tasks
People become lazy as they depend on devices
Unrealistic expectations (e.g. comparing a users progress to others data)
Biometric data not always accurate
There positive impacts of using technology
Less expensive to stay connected
Easier to make new friends
Easier to find people with similar interests
negatives of using technology
Social isolation
Increased anxiety from a lack of interaction
The way people behave online compared to offline
how are microprocessors used in transport?
monitoring and controlling of transport
traffic management (smart motorways etc.)
ANPR
Air traffic control in airports
Railway signalling
Advantages of MP on transport
Less human error, reducing number of accidents
Efficient scheduling means more trains/aeroplanes can run
ANPR can automatically penalise offences/check for insurance and cars reported stolen
Smart motorways can real-time adapt to traffic and reduce journey times/delays
Disadvantages of MP on transport
If the system fails, whole transport system is stopped
Open to be attacked by cybercriminals
ANPR is collecting data (privacy concerns)
Design flaws can lead to safety concerns
what are autonomous vehicles
make use of sensors, cameras, actuators and microprocessors to get a vehicle from point A to point B without human intervention
rely on complex algorithms to work alongside the hardware
adv of autonomous vehicles
Better for environment due to efficiency
Safer, no human error
Reduced traffic congestion due to more efficient speed, braking and lane capacity
dis of autonomous vehicles
Expensive
Security concerns, software updates and patches
Higher maintenance
Could lead to unemployment
User reluctance to new technology
What are health issues?
common side affect of the prolonged use of IT
common health issues are:
Repetitive strain injury (RSI)
Back/neck problems
Eye strain
Headaches
what is RSI
Repetitive strain injury is damage to the fingers, wrists and joints, traditionally caused by prolonged use of a keyboard and mouse
what are the effects of RSI
Pain
Numbness
Weakness
Stiffness
how to reduce risk of RSI
Have the correct posture (angle of arms to the keyboard and mouse)
Use a wrist support if necessary
Take regular breaks
Make use of ergonomic keyboards
how do we get back and neck problems?
caused from sitting in front of a computer screen for prolonged periods of time
effects of back and neck problems
Pain
Stiffness
Muscle spasms
Weakness
Numbness or tingling
Sciatica
Difficulty sleeping
how to reduce risk of back and neck problems
Use adjustable chairs
Take regular breaks
Use a foot rest
how do we get an eye strain
caused by staring at a computer screen for prolonged periods of time or incorrect lighting causing reflections
effects of eye strains
Headaches
Vision problems (blurred, double, light sensitivity)
Discomfort
how to reduce risk of eye strains
Take regular breaks
Use anti-glare screen filter
Change from CRT to LCD monitor
how are headaches caused?
Poor lighting
Flickering screens
Reflections
Fatigue
how to reduce risk of headaches
take regular breaks
Have regular eye tests
Use an anti-glare screen filter
