Computing 2.1

Computing 2.1

1. 2.1.1 - Thinking Abstractly

   • The need & nature of abstraction
     • So programs don't include data and information that isn't needed
       • Saves vast amounts of time and storage
     • To create efficient programs that complete the job needed using only the needed resources
   • The differences between abstraction & reality
     • Abstraction only includes the variables and data needed, reality includes multiple more variables and data some much more complex than needed that would make creating a program identical to reality a ridiculous task

2. 2.1.2 - Thinking Ahead

   • Nature, benefits & drawbacks of caching
   • The need for reusable program components
   • Identifying inputs and outputs of a given situation

3. 2.1.3 - Thinking Procedurally

   • Identify the components of a problem
   • Identify the components of the solution to the problem
   • Determine the steps needed to achieve a solution to the problem

4. 2.1.4 - Thinking Logically

   • Identify points in the solution where a decision needs to be made

5. 2.1.5 - Thinking Concurrently

   • Consider parts of the program that can be done at the same time 'pipelining'
