8. Data Security issues
 MC device connected to the internet can lead to cybersecurity issues.
 If you can remotely control from anywhere, so can a hacker.
 Devices are default set and no password.
 Personal details, holiday dates lost and break in your house
 Automatically order food from market, then hacker can gain key data, such as
credit card numbers.
 Make sure to manage different passwords and install updates

 Easier to make new friends using chat
rooms
 Easier to find people who share similar
interests/hobbies
 Less expensive to keep in touch using VoIP
technology
Negative
 People do not meet face-to-face as much
 Lack of social interaction & more anxious
in real life
 Behave differently when interaction online

10. Monitoring and controlling transport
 Monitoring of traffic on motorways
 Congestion zone monitoring
 Automatic number plate recognition (ANPR)
 Automatic control traffic lights
 Air traffic control systems
 Railway signaling systems

11. Control of smart road systems and smart
signs
 Smart motorways  controlled by a
central computer system
 Monitoring and control of the traffic
and displayed on the motorway signs

12. Rail and air line network control systems
 Safely coordinating the large number of trains and aeroplanes entering and
leaving stations and airports is a complex task.
 Computerized monitoring systems is possible to run a more efficient timetable
under total computer control.
 Train and aeroplane journeys are so safer because human error is removed.

13. Advantages and disadvantages of transport
monitoring and control systems
Advantages
 Reduce traffic jams
 More efficient, more cars, trains,
aeroplanes can use transport network
 Traffic offences using ANPR
 Stolen cars and criminals can be spotted
using ANPR
 Minimise huma error
Disadvantages
 Hacker gain access and cause disruption
 If systems fails, everything would be
standstill
 Poorly designed systems could
compromise safety
 ANPR can easily track innocent people’s
movement. Then, who has access to that
data?

14. Advantages and disadvantages of
autonomous vehicles
Advantages
 Safer, human error is removed
 Better for the environment
 Reduced traffic congestion
 Increased lane capacity
 Reduced travel times
 Stress-free parking for motorists
Disadvantages
 Very expensive
 Fear of hacking into the control system
 Security and safety issues (software glitches ,
software updates)
 Make sure the system is well-maintained at
all time
 Driver and passenger reluctance of new
technology
 decrease jobs for taxi drivers

15. Advantages and disadvantages of
autonomous trains
Advantages
 Improves the punctuality of the trains
 Reduced running costs
 Improved safety, human error is removed
 Minimises energy consumption
 Possible to increase the frequency of trains
 Easier to change train scheduling
Disadvantages
 Fear of hacking into the control system
 System does not work well with very busy
services
 High capital costs
 Ensuring passenger behavior is a acceptable
 Passenger reluctance of the new technology
 Need for CCTV to monitor railway stations

 Improved aerodynamics at the front of
the aeroplane
Disadvantages
 Security aspects if no pilots on-board
 Emergency situations during the flight
may be difficult to deal with
 Cybersecurity threat
 Passenger reluctance to accept new
technology
 Software glitches

18. Back and neck strain
Causes
 Sitting in front of the
computer screen for long
periods of time
Reduction
 Use fully adjustable chairs to
give the correct posture
 Use foot rests to reduce
posture problems
 Use tiltable screens, raised to
the correct height, to ensure
the neck is at the right angle

19. Repetitive Strain Injury (RSI)
Causes
 Damage to fingers and
wrists caused by continuous
use of a keyboard or
repetitive clicking of mouse
buttons
Reduction
 Ensure correct posture is
maintained
 Rest your wrist
 Take regular breaks
(+exercise)
 Use Ergonomic keyboards
 Use voice-activated software

20. Eyestrain
Causes
 Caused by staring at a
computer screen for too
long or by having incorrect
lighting in the room
Reduction
 Change LCD if CRT screen is
used
 Take regular breaks
(+exercise)
 Use of anti-glare screens
 Eye test on a regular basics

22. Ozone Irritation
Causes
 Caused by laser printers in
an office
Reduction
 Proper ventilation should
exist to lower the ozone gas
levels to acceptable values
 Laser printers should be
housed in a designated
printer room
 Change to using inkjet
printers where possible
