Computers
Getting Started
  • Desktop computers (a group which, funnily enough, includes laptops) have been around for a long time
  • This IBM PC, one of the first desktop computers, was invented in 1981

  • Computers have come a long way since then, culminating in portable machines with thousands of times as much power for a fraction of the cost

  • However, if you dig deep into these machines, certain fundamental concepts remain constant

Operating Systems
The power inside
  • If you have a Mac, it will run an operating system called macOS, which is updated every year
  • If you have a Chromebook, it will run Chrome OS, which is an operating system with a few differences
    • An operating system, or OS, is the software that lets you install and run apps on a computer.
    • Other operating systems used on other computers include Linux, Windows, Android, iOS.
  • macOS and Chrome OS are both a desktop OS, meaning they are used on desktops and laptops, not mobile devices.
    • Desktop operating systems generally have what we call WIMP:
      • Windows - boxes on the screen in which things appear.
      • Icons - images, which we can double click to open, which represent files and apps
      • Menus - lists of actions we can perform
      • Pointers - a virtual hand on screen, which we can use to manipulate windows, icons and menus.
    • We call these computers "desktops" because they replaced many of the things that used to sit on people's desks, which have now been turned into apps:

OS Basics
Digging In
  • Let's look at some of the basic things we can do with our Mac.
  • Take some time to watch the video below. Stop it as often as you need in order to understand, learn and practice the skills and ideas shown:

  • If you have a Chromebook, this video will explain some of the basics of your machine

10 mins
Finishing Up
Evidence
  • Using your new found skills:
    • Record a one-minute video where you appear on camera.
      • On Mac, use Spotlight to launch an app called Photo Booth.
      • On Chromebook, use the Launcher in the bottom corner of the screen to open the Camera
    • In your video talk about some of the ideas covered in this unit, as well as new things you learned.
    • Don't script your response, just try and speak as if you were talking to a friend.
    • Try not to record your video lots of times: do it once or twice only: it does not need to be perfect.
  • Once you have completed your video, upload the video file to this unit as evidence of your learning.
There are no records to display.
