Task 7: This task provides evidence for IP5. In computing, an interface is a shared boundary across which two or more separate components of a computer system exchange information. The exchange can be between software, computer hardware, peripheral devices, humans, and combinations of these. The data acquired by the chosen digital systems need to be communicated with a computer via an interface system. Carry out the following to select and use two suitable interfaces for your chosen systems when the data is to be uploaded to a computer:
- Define the meaning of a standard data interface.
- Give two examples of a data interface.
- Give two general applications of a data interface.
- Select, with justification, two different types of data interfaces (electrical current sourcing and heat sinking requirements; voltage level adjusting).
