Title: Components of a Computer System


1
Components of a Computer System
  • Lesson 19 Application Software

2
Learning Objectives
  • Define application software.
  • Categorise software application types into the 6
    main application groups.
  • Describe the difference between application types
    and product names.
  • Categorise uses of the 6 main application groups.
  • Describe EFTPOS.
  • State what Expert Systems do.

3
Application Software
  • Application software allow the user to produce
    something useful.

4
There are 2 main types of software
Performs tasks needed to just run the computer
system. Without system software application
software could not run.
Carries out some task/s for the user allowing the
user to produce something useful.

7
CAD
  • Computer Aided Design

8
CAM
  • Computer Aided Manufacture
  • Computer Aided Manufacturing (CAM) then makes use
    of that design to directly manufacture the
    component .

9
Measuring Programs
  • Data logging Software
  • Interprets data from sensors
  • Measures information like temperature, weight etc

10
Control Programs
  • Using a computer to control the action or
    movement of an object.

EFTPOS
  • Short for Electronic Funds Transfer Point of
    Sale.
  • Customers pay funds (transfer) from their account
    to the merchants account electronically while

Application Types and Product Names
  • The difference between the two is like the

Plenary
  • Define application software.
  • Application software allow the user to produce
    something useful.
  • Describe the difference between application types
    and product names.
  • Application types are general terms
  • Product names are the names given to programs by
    companies who have made them.
