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?
