Networking interface card (NIC)

Networking interface card (NIC):

Before a computer can be connected to a network it will need to have a network interface card. Most modern computers have these when you buy them. A network interface card is simply a card containing circuitry along with a socket.

Communication devices:

Communication devices are those pieces of hardware that are needed to turn stand-alone computers into networked computers.

Basic elements of an ICT network

There are four basic elements of an ICT network in addition to the computers themselves:

communication devices
networking devices
data transfer media
standards and procedures

Introduction:

A basic network consists of a collections of computers and other hardware devices such as printers and scanners that are linked together so that they can communicate with each other.

Introduction:

Testing should be done throughout the development of the solution. The reason for the test plan is because you would not want to proceed onto the next part of a solution unless you were sure that the first part worked properly.

It is vital to keep tracking of all the tests you have performed. This is then put together in a document called a test plan.

Working on Implementation

As you work through the implementation you should check your work is satisfying the designs laid down by your client and also what you produce is workable in the user’s environment. Much of this comes under the banner of testing and therefore needs to be placed in your testing folder.

Any change you make to the design of your solution should be noted as this forms part of the testing of your solution.

Sample Question

You have agreed to set up an electronic photo album to display family photographs.

Explain how you would load and organise these photos on your PC.
(3 marks)

How would you load older non-digital photos onto your PC?
(2 marks)

During the implementation process, it is useful to produce evidence such as:

Screenshots
Printouts
Annotated printouts
Sound recordings (in a suitable format such as; mp3, wav, m3u etc.)
Photographs or images
Text
Videos (in a suitable format such as; mp4, avi, mkv etc.)

Exam Tips

Always make sure that what you implement is what was set out in the design stage.
If you need to make any changes then this is alright but you must explain why the change to the design was needed.
Get into the habit of writing clear explanations as to what you are doing.
You will have to produce explanations as part of the exam; show your explanations to others and see if they can understand them.
