Intro to Computer Science
Getting Started
  • Welcome to CSE-A!
    • In this course we'll be programming with variables, loops, functions, and different data types.
    • You'll have the opportunity to create computer art and games, and learn web design through HTML, CSS and Javascript.
    • We'll also be exploring topics like computer architecture, data storage, binary and boolean logic.
    • Different units will give you the option to work in groups as well as individually.
    • The course completes with a final project which can follow an area of your own interest.

What is a Computer?
The Basics
  • The best way to start learning about computer science to to ask:
    • What is a computer?
    • How does it work?

  • In this video, we saw the four main steps of how computers work:

  • Consider the devices and computers you use:
    • What kinds of inputs do you interact with?
    • Where is the data stored? Is it local, or in the cloud?
    • How fast is the processing done?
    • How many different kinds of output can a computer produce?

Computer Science Concepts
  • Computer Science involves a lot of new concepts and terminology.
  • A key to your success in this course will be to keep track of these new terms.
  • To help you keep track, please do the following:
    • Create a new slideshow in Google Slides called Computer Science Concepts.
    • Pick a theme for your slideshow.
    • Add the first slide with a title and your name.
  • Add one slide for each of the following concepts:
    • Input
    • Storage
    • Processing
    • Output
  • For each slide, add:
    • A short definition, in your own words.
    • An image to illustrate this concept.
    • At least one link to a website or video that helps explain this concept.
    • Don't forget to cite your sources
  • We'll be adding concepts to your slideshow throughout this course. You are also welcome to add your own slides to keep track of new terms and ideas.
  • Once you have finished, submit the link to your slideshow as evidence of learning in this unit.
