2.1       What is Computer Applications Technology?
Computer Applications Technology is the study of the integrated components of a computer system (such as
hardware, software and software applications) and the practical techniques for their efficient use and application
to solve everyday life problems. The solutions to problems are designed, managed and processed via end-user
applications and communicated with the appropriate information and communication technologies (ICTs). ICTs
are the combination of networks, hardware and software as well as the means of communication, collaboration
and engagement that enable the processing, management and exchange of data, information and knowledge.

The diagram below illustrates how the main topic areas of the Computer Applications Technology subject support
the development of digitally enabled learners.

In Computer Applications Technology a learner will
      ƒ   Be able to use end-user software applications proficiently to produce solutions to problems within a
          defined scenario.
      ƒ   Understand the concepts of ICTs with regard to the technologies that make up a computing system.
      ƒ   Understand the various technologies, standards and protocols involved in the electronic transmission of
          data via a computer-based network.
      ƒ   Comprehend the Internet and the WWW and the role that the Internet plays as part of the global
          information superhighway.
      ƒ   Have the ability to find authentic and relevant information, process the information to draw conclusions,
          make decisions and communicate the findings in appropriate presentation media.
      ƒ   Understand how the use of ICTs affects modern-day living, recognise the legal, ethical, environmental,
          social, security and health issues regarding the use of ICTs and use ICTs responsibly.

                                                                                                      7|P a g e

Topic links and overlap

It is important to note that there will always be a degree of overlap between topics. Solution development is
enabled by systems technologies in the form of application software. Systems technologies allow for electronic
communication. Network technologies enable the Internet that is used for various applications which include
information dissemination and electronic data interchange. Data and information management is a key concept
and secondary activity overlapping concepts in many other areas such as solution development and Internet
technologies. Data and information management is enabled by systems technologies. All ICT activities are
primarily driven by human involvement, need and intervention, which in turn highlight social and ethical issues.

For example, when one deals with Information Management, one could incorporate the topic with the Internet
Technologies and application software involved in Solution Development. This is also applicable to the Systems
Technologies topic where the Social Implications concerned could also be highlighted.

2.4       Infrastructure, equipment and finances for offering Computer Applications Technology
Infrastructure, equipment and finances for the subject are the responsibility of the school.
(Refer to circular S7 of 2006)

In Computer Applications Technology learners are required to work individually on a computer during contact time
and need to access the Internet.
Schools should have a business plan for the subject that addresses the following:
      ƒ   Initial capital layout for setting up a computer laboratory. The layout should provide for the following:
                o Entrance level computers (to ensure a lifespan of 4 – 5 years), networked
                           ƒ One computer per learner per period (during contact time)
                           ƒ Provision for sufficient computers to enable the practical examination to be completed
                               in at most two sittings
                o One high-speed printer per network
                o Internet access
                o Data projector or demonstrating software
                o Software (operating system, Office suite, security software – antivirus, Internet security)
      ƒ   Budget
                o Annual running costs
                           ƒ Software licensing (operating system, application software, security software)
                               (Provinces to negotiate collective agreements)
                           ƒ Cartridges, paper, storage media
                           ƒ Breakage and maintenance (regular service plan)
                           ƒ Insurance
                       ƒ    Internet connectivity
              o    Sustainability plan
                       ƒ To upgrade or replace software and equipment every 4 – 5 years.

3.2            Systems Technologies
Systems technologies are the physical and non-physical components of a computer system. The components of
the system are independent units which are designed to perform a particular function. These components which
include hardware, peripherals and software components are connected as a unit to perform the basic functions of
a computing system, which include input, processing, output, storage, communication and transfer of data in an
electronic format.

     Note:
     Hardware and software should be dealt with at a non-technical level but which will enable the learner to:
           o    understand the concepts that make up a computer system;
           o    troubleshoot at an elementary level or select the most appropriate hardware for a given scenario;
           o    know whether to upgrade or buy new equipment;
           o    be aware of new trends and developments and how to integrate these with existing or new equipment;
           o    know how technology can benefit the user in specific contexts.
           o    understand the operations involved in the management and optimal utilisation of a computer system.
     Content in this focus area should be taught from a basis of familiar contexts (what learners are busy with) to unfamiliar
     contexts (new trends and developments). This focus area lends itself meaningfully to integrate content from the Social
     Implications and Internet and Network Technologies focus areas, and should be taught likewise.

                                                                                                                    11|P a g e 
3.3            Network Technologies
Network technologies include various network technologies to facilitate the management and dissemination of
digital data from one point to another. Network technologies also incorporate the electronic systems used for
electronic data interchange that is used to facilitate information dissemination between various individuals or
groups at a single point or dispersed locations.

     understand the concepts of the various technologies and the standards and protocols involved in the electronic
     transmission of data via a computer-based network.
     Learners should be able to do troubleshooting at an elementary level and be of aware of new trends and developments.

     Note:
     Learners should be able to:
           o    provide an overview and understanding of how ICTs affect modern-day living;
           o    use ICTs responsibly.
     Most of the content of Social Implications should be dealt with and integrated with other topics on a need-to-know / just-in-
     time basis and should not be taught as a stand-alone topic. The time scheduled for this topic could therefore be added to
     other topics if necessary.

                                                                                                                  15|P a g e
