In all of the tables in this document, both the pre-2009 NQF Level and the NQF Level is shown. In the text (purpose statements, qualification rules, etc), any references to NQF Levels are to the pre-2009 levels unless specifically stated otherwise.  

This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
This unit standard is intended:
  • To provide fundamental knowledge of the areas covered.
  • For those working in, or entering the workplace in the area of Hardware, Infrastructure Maintenance and Support.
  • As additional knowledge for those wanting to understand the areas covered.

    People credited with this unit standard are able to:
  • Perform Boolean logic algebra operations.
  • Demonstrate knowledge of logic gates.
  • Convert numbers using decoders and encoders.
  • Demonstrate knowledge of the general principles of logic devices.
  • Demonstrate knowledge of integrated circuit specifications.

    The performance of all elements is to a standard that allows for further learning in this area. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
