Karten in diesem Stapel (50)
- 1Heuristicdiscovering knowledge through experience
- 2Biometricsthe measurement of a person's physical characteristics
- 3Cloud computingusing remote servers hosted on the internet to store data
- 4Encryptconverting data into a scrambled code
- 5Keya sequence or algorithm used to encrypt or decrypt data
- 63D printingobject is created based upon a blueprint made with modelling software; takes thousands and thousands of cross-section layers of the model
- 7What can 3D printing do?- create more flexible casts
- replacement organs
- artificial blood vessels
- houses
- automobile parts for vehicles in space that NASA can create - 8Potential of 3D printing- build houses mean in the event of a natural disaster, affected people can be housed quickly
- no waiting for organ donor
- no worries of blood match
- team no need to abort in space if part of spacecraft is broken - 9Drawbacks of 3D printing- gun (safety issues)
- plastic to create (not environmentally friendly) - 104G and 5G cellular communications3G allowed broadband speeds for the internet. 2G wasn't robust or fast enough to deal with the rapidly increasing number of mobile phone users.
3G signal is passed from each cellular mast or phone tower. - 114Gincreased upload & download speeds and reduced latency; quicker response
- 12Benefits of 4G- greater speed in internet access
- fast loading speeds of application
- multiple people in video conferencing calls
- more effective location services
- stream HD - 13Artificial intelligencea computer that is able to make decisions based upon stimuli
also used in self-driving cars (such as Telsa), and also in Siri and Google Now - 14Impact of AI- people with disabilities can use voice-activated systems
- self-driving cars can help people with disabilities to travel independently
- entertainment
- diagnosis - 15Drawbacks of AI- self-driving cars have a debate on who should pay in the event of an accident
- voice activated systems are improving but still suffer from input errors
- only as good as its programming - 16Augmented realitywhere technology overlays computer-generated images onto the real world. It works by taking signals from the real world using a camera, checking to see if there's a point in the camera image that is telling it to draw an image on screen
- 17What are examples of augmented reality's uses?- google glass
- computer games, such as Nintendo 3Ds - 18Potential issues of augmented reality- google glass can impede your vision
- issues with object recognition due to lighting or angle
- google glass can suffer from security issues - 19Biometricsthe use of technology to track user values, being as simple as heart rate or voice recognition software, fingerprint and iris recognition. It works by taking several examples, saving the data and attaching to a user account. The input data is then compared with the stored values to determine if there's a match
- 20Pros of biometrics- mobile devices & laptops have fingerprint recognition
- some airports can read biometric passports - 21Cons of biometrics- personal data are stored that can be used against someone
- nothing stopping a user from presenting a fake biometric material
- some feel that their human rights are being violated through the collection and use of their biological data for security reasons - 22Cloud computinga collection of servers are used to store or process data instead of doing this on your own computer
- 23Pros of cloud computing- online services provide this, allowing you to upload own files and access on different computers
- data can be uploaded from numerous devices
- can process data - 24Cons of cloud computing- security
- constant need for internet connection - 25Computer-assisted translationworks by giving the software either a document or a string of text which the software then removes anything that isn't text and translate it into the language of choice
- 26Pros of computer-assisted translation- easily and quickly translate in a foreign country
- can translate whole documents and websites, making it possible to read them - 27Cons of computer-assisted translation- direct translation rather than the meaning behind the sentence
- restructuring grammar across translations, picking the correct meaning of a word that has multiple uses and handling issues where there is no actual translation for the word in question - 28Holographic & fourth generation optical data storagemagnetic & optical rely on bit of data being stored as magnetic or optical changes on the surface of the medium. holographic data works by recording data throughout the volume of the medium
this stores bits in parallel, meaning many bits are stored layer upon layer - 29Pros of holographic data storagecompanies can achieve vast amounts of data for a long period of time (degrade less than others)
- 30Cons of holographic data storagetechnology develops & moves on so rapidly that in years the technology to read holographic storage may no longer be available
- 31Holographic imagingaka holography- ability to make holograms. it's a 3D image created with photographic projections and is free-standing.
doesn't mimic depth like a 3D image - 32Potential of holographic imagingin time, it may be possible to transmit a hologram electronically to special devices in our home or workplace
- 33Quantum crptographysafest method of encryption- not use algorithms but physics.
data is transmitted using fiber optical cable. it's made of light particles that vibrate individually in all directions (polarising). it will pass a filter that will unscramble the data. - 34Drawbacks of quantum crptographyonly short distance (60 km)
- 35Roboticscreation of computers that perform tasks that humans cannot or less efficient at performing. they have a processor that control its movements and are used in manufacturing
- 36Pros of robotics- mundane & repetitive tasks
- dangerous tasks
- entertainment value and can be used for everyday tasks - 37Cons of robotics- many people are angry when humans are "replaced" by robots
- scared by the ability of robots
- cannot respond to emotion and can only do tasks they are programmed to do - 38QR codeaka Quick Response- type of barcode that is made up of black & white squares which are printed on products to give extra information. it's then scanned which will carry out an action such as linking to a page
- 39Benefits of QR code- gyms can use these for equipment demonstration
- foods to share more information about the product or company
- marketing purposes
- user has choice to learn more about the product
- trigger to open different applications - 40Drawbacks of QR code- based on image processing so can only be scanned when there's enough light
- distorted when resized
- need space
- often a link and without stable internet connection, you may not be able to access the linked information - 41Wearable computingthey can take many forms, however there are two major forms (fitness devices and smartwatches)
- 42Pros of wearable computing- fitness device can be worn to measure activities such as sleep patterns, calories burn
- 43Cons of wearable computing- expensive
- easily subject to moisture
- connectivity (bluetooth or wifi) - 44Ultra-high definition TVvery high quality TV
- 45Pros of ultra-high definition TV- not enough content in that high quality
- expensive
- difficult to stream because of the amount of required bandwidth - 46Vision enhancementprovide blind people with images of their surroundings
+ colour blind people - 47Virtual realitya 3D space created by the computer
- 48How is VR achieved?users wear gears such as headsets, omni-directional treadmills and special gloves
- 49Drawbacks of VR- motion sickness due to the mismatch of reality and what we see
- risk of injury
- some experiences of seizures - 50Applications of VR outside games- medical procedures allowing doctors to practice surgery
- flight simulators
