The Ways In Which
ICT
Is Used
7.2
Communications
Applications
Methods of communications
VOIP system
emails
Video Conference
Ways of communicating information
music production
printing flyers and posters
multimedia presentations
cartoons and animations
websites
7.3
Satellite & mobile
network
communications
Mobile phone networks
Mobile phones communicate by using towers inside many cells connected together
EWT
Embedded web technology is a new development that uses internet in real time to connect with another device
GPS
Global Positioning Satellite systems are used to determine the exact position of a vehicle.
7.4
Data handling
Applications
surveys
tuck shop records
club and society records
Typical data protection act
record keeping
7.5
Modelling
Applications
Simulations
What is a Simulation
a simulation is the creation of a
model of a real system in order to study the behavior of the system
Using the simulation
Firstly, the sensors collect data.
Transfer the data to computer(convert the data first if necessary)
Compare the data given to the data stored in system.
The control box or computer decides what to do.
Signas are sent to the traffic lights to change their timing if necessary.
why simulations are used
less expensive than building the real thing
safer to run a simulation
various simulations can be use
It is faster to do a simulation than the real thing.
traffic light simulation
carrying out the simulation
data from above is entered to the computer and the simulation run
increase or decrease traffic flow
vary the timing of the lights and see how traffic flow is affected
how emergency vehicles affect traffic flow at different types of day
data collection
the number of vehicles passing
the time of day for vehicle count
how long it takes for a
vehicle to move from conjunction
environmental factors such as pedestrians weather
Limitations
Only good as the data used and the mathematical algorithm represent ing the real-life situatuions. Limited use in some very complex applications.
Can be expensive since specialists are needed.
Oftenly require very fast processors/computer system.
7.6
Types of
Processing
batch processing
number of tasks are all collected together
real time processsing
reak time process control
7.7
Control
Applications
turtle graphics
Turtle graphics is based on the LOGO programing language.
It is basically the control of the movement of a 'turtle' on a computer screen by a number of key instructions .
common commands
left - turn left through X degrees
right - turn right through X degrees.
Backward - moving a certain distance backward.
Repeat - repeat the set instruction for X times.
Forward - moving a certain distance forward
endrepeat - finish the repeat loop
pen up - lift the pen up
pen down- lowering the pen.
combining and using these simple commands , shapes and pictures could be drawn.
use of sensors to control or monitor application
monitoring
THe computer reviews the data from the sensors and updates its file and/or gives a warning signal if the values are outside the parameter
examples of monitoring includes
monitoring a patients vital signs in the hospital
monitoring a scientific experiment in a laboratory
a burglar alarm system
environmental monitoring
conrtolling
reviews the data from the sensors but if the values are outside the parameter it takes action and tries to get the values within acceptable range
examples of monitoring includes
controlling a chemical process
controlling a greenhouse environment
controlling a nuclear reactor
controlling a set of traffic lights.

7.8
Robotics
Robots are used in all kinds of manufacturing jobs
Pros
Robots can work in harmful environments as they are not affected
They can work 24/7 non-stop
They can do boring, repetitive tasks
Cons
Robots find it difficult to do unusual tasks
They replace skilled labor leading to unemployment
Risk of de-skilling
7.9
Batch

Applications
cheques
billing system
7.10
Automatic
Stock Control
7.11
Online
Booking
Systems
The customer clicks on the performance they wish to see
they enter the date and time of the performance and the number of required seats
The data base is searched to check the availability of the selected seats. If the seating plan is shown on the screen, this step is not required
A seating display at the theatre is then shown on the screen and the user clicks on where they would like to sit
If the seats are available, the seat numbers are shown together with the total price.
If the customer is happy they choose the seat
Seats set at temporarily not available
Customer enters Personal data

Expert
Systems
What is an
Expert System
Mimics the expertise and
the knowledge of an expert.
For example:
Diagnostics
Prospecting for oil and minerals
Identification of plats,
animals and chemical compounds.
Tax and financial calculations
Road scheduling for delivery vehicles
Diagnosing a person's illness
Chess games
Knowledge base
Rules base
Inference engine
User interface
PROS
Consistent answers
Reduces time taken to solve a problem.
A less skilled work force is needed, which potentially saves money.
CONS
Tend to lack common sense.
Errors in the knowledge base can cause wrong decision.
It can be expensive to set up in the first place.
