UNIT 6: RANGE OF COMMUNICATION APPLICATIONS
Range of communication applications: Newsletters, Websites and Multimedia presentations, music scores, Cartoons, Flyers and posters
The use of mobile phones in communications: Text messaging, phone calls, and accessing the internet
WHAT IS VOICE OVER INTERNET PROTOCOL (VOIP)?
VOIP,is a method and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol networks, such as the Internet
Applications that are used for publicity
: Flyers, Leaflets, Internet use
(social media: Instagram, Snapchat, Facebook, Twitter etc.)
RANGE OF DATA HANDLING APPLICATIONS
: Surveys, address lists, clubs and society records, school records and school libraries
RANGE OF MEASUREMENT APPLICATIONS
: Scientific experiments and weather stations
The
Difference
between
analogue
and
digital
data:
Analogue data
cannot be read by a human being. this is the data that comes out of the machines immediately after generating a report.
Digital data
is the one that can be read by a human, and is done by converting the
Analogue
data
into readable format.
The use of
Microprocessors
and
Computers
in a number of applications: Such as in:
Pollution Monitoring, Intensive Care Units (ICU) in hospitals
Advantages and Disadvantages of Using Computers in Measurements:
The Advantages
: Computers will give/ produce a more accurate report than a human. Computers can produce reports in any weather, or situation. Computers can also generate reports in sever conditions.
The Disadvantages
: They may be broken and therefore cannot produce a report for that specific amount of time. The conversion system may break down and therefore the data cannot be converted from
analogue
to
digital
data: therefore the report produced will become useless
What is the role of a
pre-set
value?: These allow the machines to be more user friendly and also makes the work process faster.
Computer Control in application in places like:
Turtle graphics, Automatic Washing Machines, Automatic Cookers, Computer Controlled Central Heating System, Burglar Alarms, Computer Controlled Glasshouse
The following are a example of control systems
turtle graphics
control of lights, buzzers and motors
automatic washing machines
automatic cookers
central heating controllers
burglar alarms
video recorders / players
microwave ovens
computer controlled greenhouse
