Advantages: Saves cost of travelling, reduction of
travelling is better for the environment, and the
flexibility in working hours to suit someone's
needs
Disadvantages: You need a good and
reliable internet connection, you might be
interrupted by a family member or
friend or even your phone/TV
Online banking
Advantages: Banks save money by
having fewer branches, Require
username and password AND pin
so that its difficult to hack
Disadvantages: Bank staff need
paying- loss of money, Can be hacked,
Not everyone has accsess to a
phone/computer
Artificial Intelligence
This is a computer science hat is
focused on creating computer systems
that simulate human intelligence
E.G: Game playing, Expert systems, Robots
Virtual reality
Virtual reality is where computers are
used to create an artificial environment
that users can interact with as if it were
real
Virtual reality is not meant for gaming purposes.
E.G: allowing architects to walk around a
virtual version of their design, Training
soldiers in combat (flight simulation/
battlefield simulation), training surgeons
(Virual patients can be operated on to provide
experience to trainee surgeons
Holographic Imaging
This is a technique where images are
made to appear 3D and to look like they
have depth. Holograms work by taking 2
normal 2d images and layering one on
the other. The 2D images must be shot at
different angles.
E.G: Sensors/Biosensors,
Microscopy, Medical Uses, Art
work etc
Quantum Cryptography
Quantam Cryptography is technology which
allows messages and data to be sent with
complete privacy. Quantam crypography encrypts
the data using physics so that it is impossible to
break unless you have the code. Messages are
encrypted using photons, these are tiny packets of
light.
3D Printing
Making 3D solid objects
from a digital file
It is done by laying down successive layers of material until the desired object is created.
Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual
object
Vision Enhancement
Ict can help people see better. The
use of zoom facilities In software
helps a lot and so does the ability
to change the background colour,
font size, font colour, font and
styles. ICT can help peple see at
night: E.G: Night vision goggles and
car display screens
