Starter What do you think is the difference between

and output device and the output from a system?

System output – the information being produced

Output device – the device that produces the information

E.g. An exam system may produce charts showing candidate number and marks (system output) which is printed from a laser printer (output device)

2.2 Selecting Output Devices

INFO1 – Practical problem solving in the digital world

What should you consider before selecting a screen / monitor? The main issues are:

◦ Screen size◦ Screen resolution

Other considerations:◦ What kind of image needs to be viewed?◦ Where is it going to be viewed?◦ Who is viewing the image?◦ Internet access to the content.

What kind of image needs to be viewed? What type of monitor would you select for a

web or graphic designer? What about for an office worker? Why?

Where is it going to be viewed? What device would you choose for a

business man who needs to work on the move?

What about in a greasy / dirty environment e.g. food factory?

Who is going to view the image? How could you adapt a screen / monitor for

someone who is partially sited? How would you show an image to a large

audience? What would you use in a reception area of a

company?

What should you consider before selecting a printer?

What is to be printed? How many documents? What kind of media? Who uses the printer? Running costs?

What is to be printed? What would you choose for a solicitors

office? What would you choose for a graphics

department of a web company?
