The document discusses various input and output devices as well as new technologies. It describes manual input devices that require human entry of data and direct data entry devices that transfer information automatically. Key criteria for comparing input devices are outlined. Examples of input devices include keyboards, mice, scanners, and cameras. Output devices discussed include printers, monitors, and 3D printers. New technologies summarized include artificial intelligence, biometrics, quantum cryptography, computer assisted translation, virtual reality, and 3D/holographic imaging. Their applications and impacts on everyday life are briefly described.

1. An input device transfers data from the outside world into a
computer.
2. There are two different categories of input device. They are :
 Manual input devices: User must enter data into the computer
by hand.
 Direct Data Entry (DDE) Devices : Transfers information
automatically from a source document such as a form or barcode
into the computer.
3. Important criteria for comparing input devices are : suitability to
application, input speed, cost and reliability. 4. There are many
different input devices available. The key features of each input
device are outlined in the table below.

8. Radio Frequency IdentificationRadio Frequency Identification
What is it?
Is an abbreviation for Radio Frequency
Identification.
This is a term used to describe a type of
wireless technology used to identify
objects, animals (or people)

9. RFID systems can be used just about anywhere:
from clothing
Missiles
pet tags
food
anywhere that a unique identification system is
needed. The tag can carry information as simple
as a pet owners name and address to as complex
as instructions on how to assemble a car.
Some auto manufacturers use RFID systems to:
move cars through an assembly line. At each
successive stage of production,
the RFID tag tells the computers what the next
step of automated assembly is.

10. 1. Businesses that want to keep track of their stock as it
moves from one place to another.
For example, many parcel delivery companies now offer
the ability for you to check where your parcel is as it is
being delivered. They can do this by attaching an RFID
tag on the parcel, then a reader at each main point of its
journey keeps track of its progress.
2. Security systems that can sense the identity of the
person wanting access to a restricted area.
The person wears an RFID tag, so when they approach
a reader, it can request an identity check without the
person having to do anything.

11. 3. Anti-theft
Many shops use RFID to deter shop-lifting. Have you noticed
some shops have some tall objects standing either side of the
doors? You have to walk between them in order to leave the
shop. This is part of an RFID system. Many of the more
expensive items in the shop will have hidden RFID tags. If you
try and walk out of the shop, the Readers either side will
request the tag for its code - that code is checked against a
database to see if it has been paid for yet. If not, the alarm
sounds. Another reader is located beneath the desk by the
till. As you pay, they slide the object over the reader to
register it is as having been been paid for.
4. Passports.
Many countries, including the UK now use RFID tags inside
passports. The tag not only identifies the person, but also
stores a digital photograph and a record of their movement
in and out of the country. In order to reduce the chance of
someone 'skimming' that information, the passport contains a
metal film to prevent them being read when closed.

15. 3D printers3D printers
3D printing or additive manufacturing is
a process of making three dimensional
solid objects from a digital file. The
creation of a 3D printedobject is
achieved using additive processes. In an
additive process an object is created by
laying down successive layers of material
until the entire object is created.

17. What is Monitor LEDWhat is Monitor LED
Light-Emitting Diode (LED) Monitors.
Light-emitting diode (LED)
computer monitors do not use cold-
cathode technology and fluorescent
technology. Instead, light diodes
illuminate the screen in one of two
different ways, or a combination of both.

19. NewTechnologiesNewTechnologies

20. Definition:
New technologies are those that are
currently being developed or will be
developed in the next 5 to 10 years,
and which will alter the business and
social environment.

21. The technologies include;The technologies include;
Artificial Intelligence
Biometrics
Robotics
Quantum Cryptography
Computer assisted translation
3D and holographic imaging
Virtual reality

22. Artificial Intelligence (AI)Artificial Intelligence (AI)
 This is a computer science
that is focused on creating
computer systems
that simulate human
intelligence.
Impacts of AI on everyday
life:
 Accurate prediction of
weather
 Increased leisure time
 Safe Transport-driverless
trains, cars that self park
 Improved medical care-
robotic surgery assistants

23. BIOMETRICSBIOMETRICS
Biometrics is where parts of
a person's body are used
for identification
purposes.
Impacts of Biometrics on
everyday life:
 Better airport security
 Increased building
security
 Reduced car theft
 Face recognition
software can recognize
people.
 More secure mobile
phones

24. Quantum CryptographyQuantum Cryptography
Quantum cryptography
(encryption) is an emerging
technology that
allows messages and
data to be sent with
complete privacy.
Impacts of Quantum
Encryption on everyday
life:
 Completely secure voting
 Completely secure
communication
 Completely secure bank
transfers

25. Computer Assisted TranslationComputer Assisted Translation
(CAT) (CAT)
Impacts of Computer
Aided Translation on
everyday life:
 More accurate documents
 A more multilingual society-
language translators
 Quicker and more efficient
translations

26. 3D and Holographic Imaging (aka3D and Holographic Imaging (aka
holograms)holograms)
Def: This is a technique where images
are made to appear three-
dimensional and to actually
have depth.
Impacts of 3D Imaging on everyday
life:
 Improved security
 Better movie experiences
 Greater data storage

27. Virtual RealityVirtual Reality
Virtual reality is where computers are
used to create an artificial
environment that users can interact
with as if it were real.
Impacts of Virtual Reality on everyday life:
 Improved medical surgeons
 Larger and stronger buildings
 Training in dangerous situations
 More realistic education-
 More effective treatment of phobias
