Unit 2: Week 3: Peripherals

Essential Questions

  • What are the best choices for increasing the capacity of a computer workstation? What kinds of peripherals or interaction devices should I install? What options do I have? What do they do?
  • What options are there to configure printers?

Big Ideas

Different peripherals–devices you can add to your system–continue to expand the capacity of a computing device. Some of these are really critical, like a display device or an input device like a mouse. Others are optional but very common. Printers are still used by many computer users, and there are a variety of settings you can change in relation to printers.

Many people create or share a lot of multimedia files through their computers now, so it’s also important to know how to install common multimedia and imaging devices, like webcams, digital cameras, microphones, speakers, and other devices.

Connection to Student Lives

It’s pretty rare that you would use a computer for just a single use. And the way you use a computer can be different from other people, like your parents, friends, or even different teachers in your school. You have a lot of options to configure a computer system to best meet the needs of different users, whether those are simply people who use them for correspondence, others who create digital art and videos, or gamers who really want a lot of power.

While you may be familiar with common peripherals, like a monitor or a mouse, even those peripherals have several options. This module will help you explore some of the different options that you may run across for using computers in different settings.

Framing Problem

What are the best human interaction devices and printers for a given setting? Given different types of users, team members should be able to install and configure different peripherals that best meet the needs of those users.

Cornerstone Assessment

Students will install and configure peripheral options to a computer workstation. The devices should include at least one type of display device, human interaction devices that allow users to input information, a printer, and at least one multimedia or imaging device. Special emphasis should be placed on configuring a printer and understanding different configuration settings.
