We use a lot of collecting hardware on a daily basis without thinking all that much about how it works or why. That will be the focus of today's lesson. 
  1. Consider the keyboards at your desktop computers and your laptops.
    • How are they similar? (Tip: look very closely!) How can you account for the common features?
    • Are there any major differences? Explain why features have been changed between the two keyboards.
    • The keys on a keyboard do not all function in the same way. See if you can group the keys into different categories.
    • Explain why the alphabet keys are arranged in such an unusual way, and research the alternative key layouts.
    • With a maximum of three attempts, what is the highest score you can achieve on TypingTest.com?

  2. Now, consider mice!
    • Why are they called mice?
    • What kinds of data does a typical mouse produce?
    • Compare and contrast between rolling ball mice and optical mice.
    • Explain why mice are poorly suited for illustration purposes.
