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 entering the workplace in the area of Data Communications & Networking. · As additional knowledge for those wanting to understand the areas covered. People credited with this unit standard are able to: · Explain wide area computer networks (WAN`s) · Evaluate a wide area network (WAN) · Explain network administration 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 |
|
The credit value of this unit is based on a person having prior knowledge and skills to: · Demonstrate an understanding of fundamental mathematics (at least NQF level 3). · Demonstrate PC competency skills (End-User Computing unit Standards, at least up to NQF level 3.). · Describe data communications. · Demonstrate an understanding of local area computer networks, by installing a networked workstation. |
