Big Idea 1

1.1 Collaboration

  • Increases diversity

    • Allows biases can be avoided
    • Ensures maximum people are happy with the finished product

  • Connects the user and developers

    • Both parties know what to expect of each other
    • Feedback can be given to the developers to make their website better

1.2 Program Function and Purpose

  • Computer innovations are created for a purpose and that purpose guides their developments
  • Helps solve issues

1.3 Program Design and Development

  • Programs starts with an idea and developers follow specific steps to do that
  • How a program is developed
    1. Investigation: understanding constraints and requirements of the program as well as its audience
    2. Designing the program: making a plan for how the program should look and how it must work
    3. Decide on program requirements: creating a prototype of the program with its specifications
    4. Testing: seeing if everything works as intended individually and throughout the whole program
    5. Refining and revising: making changes based on feedback, testing, and reflections

1.4 Identifing and Correcting Errors

  • Errors are common in a programming setting
  • Three types of problems
    1. Logic error: a bug which causes code to run incorrectly
    2. Syntax error: an error casued by typos, missing code, or code that doesnt follow the rules of the language
    3. Run-time error: when a program fails when running
  • Programs need ot be tested to ensure they are working as intended
