Unit -5 The effects of using IT.pptx
- 1. The effects of using IT INSTRUCTOR: TR. THET ZIN 1
- 3. Positive and Negative Effects of using IT Lifestyle Leisure time Physical fitness Data security Social interaction NIEC Tachileik 3
- 4. Labour-saving devices Automatic washing machines Microwave ovens Cookers Automatic dishwashers Robotic vacuum cleaners Bread-making machines Smart fridges and freezers NIEC Tachileik 4
- 5. Other devices Alarm clocks Television sets Central heating and air-conditioning systems Home entertainment systems Mobile phones and tablets NIEC Tachileik 5
- 6. Advantages and disadvantages of MC labour-saving devices Advantages Automatic More leisure time No need to stay home for chores Automated burglar alarms Smart fridges and freezers Disadvantages Unhealthy lifestyles Lazy Lose household skills Risk of cybersecurity threats NIEC Tachileik 6
- 7. General Advantages and disadvantage of using all MC devices Advantages Save energy Easier programming to perform task Disadvantages Wasteful society Complex to operate Wasteful of electricity NIEC Tachileik 7
- 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 NIEC Tachileik 8
- 9. Social interactions Positive 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 NIEC Tachileik 9
- 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 NIEC Tachileik 10
- 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 NIEC Tachileik 11
- 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. NIEC Tachileik 12
- 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? NIEC Tachileik 13
- 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 NIEC Tachileik 14
- 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 NIEC Tachileik 15
- 16. Advantages and disadvantages of pilotless aeroplanes Advantages Improvement in passenger comfort Reduced running costs Improved safety, 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 NIEC Tachileik 16

- 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 NIEC Tachileik 18
- 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 NIEC Tachileik 19
- 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 NIEC Tachileik 20
- 21. Headaches Causes Caused by incorrect lighting, screen reflections, flickering screens and so on Reduction Use of anti-glare screen Take regular break (+exercise) Eye test on a regular basics NIEC Tachileik 21
- 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 NIEC Tachileik 22
