Year 7 revision 7.3

1. Computational Thinking

   • Computational thinking allows us to take a complex problem, understand what the problem is and develop possible solutions
     • We can prevent these solutions in a way that a computer, a human or both can understand

2. Abstraction

   • Focusing of the important information only
     • Ignoring the details that are not needed
   • Decomposition
     • Breaking down a complex problem or system into smaller, more manageable parts

3. Pattern Recognition

   • Looking for similarities among and within problems
     • Looking for patterns

4. Algorithms

   • Developing a step-by-step solution to the problem, or the rules to follow to solve the problem

5. Sequence

   • Following an ordered set of instructions

6. Selection

   • Making a decision within a computer program to decide which instruction to carry out next

7. Terminator

   • Shows the start and stop points of the algorithm (flowchart)

8. Decision

   • A decision, either yes or no
     • Deciding which instruction to carry out next in the algorithm

9. Process

   • An instruction or command

10. Input

    • Output
      • An output is a data sent from a computer
    • An input is data received by a computer

11. Connector

    • Connects the flowchart shapes
    • The arrow shows the direction or flow of instructions
