Study Notes
Computational Thinking
- Computational thinking involves several key techniques used to approach and solve complex problems
- The techniques used in computational thinking include decomposition, pattern recognition, abstraction, algorithm design, generalization, evaluation, logical reasoning, optimization, simulation, and debugging.
- Decomposition - Breaks down complex problems into smaller, more manageable sub-problems.
- Pattern Recognition - Recognizes patterns or regularities within data.
- Abstraction - Focuses on the essential details and hides unnecessary complexities, creating a high-level representation to capture the most important aspects.
- Algorithm Design - Creates step-by-step plans or algorithms to solve a problem.
- Generalization - Appliies solutions from one problem to similar problems.
- Evaluation - Assesses the quality and effectiveness of a solution by critically thinking and determining whether the solution meets the desired goals.
- Logical Reasoning - Applies logic and reasoning to analyze problems and make informed decisions.
- Optimization - Finds the most efficient solution while considering constraints.
- Simulation - Creates models or simulations of real-world systems to understand behavior and make predictions.
- Debugging - Identifies and corrects errors or fixes problems in code or solutions.
Problem Analysis
- Problem analysis is a systematic process of examining a problem to understand its causes and potential solutions.
- The goal of problem analysis is to break down a complex problem, identify its underlying causes, and generate insights to guide solutions.
Basic Flowchart Symbols & Uses
- Flowchart symbols help visually represent a program's flow and logic.
- Start/End: Indicates the beginning or end of a flowchart.
- Process: Represents a step or operation performed by the program.
- Input/Output: Shows input or output operations, like user input or data display.
- Decision: Represents a decision point in the flowchart.
- Connector: Links different parts of the flowchart.
- Subroutine: Indicates the use of a predefined function or procedure.
Programming Languages
- A programming language is used to communicate instructions to a computer.
- Low-level Programming Languages are machine-dependent (0s and 1s), run directly by the processor, and are generally faster.
- Machine Language is the lowest level, represented in binary or hexadecimal form.
- Assembly Language is a slightly higher level, written in symbolic form and requires an assembler to convert to machine code.
- High-level Programming Languages are designed for user-friendliness and are typically independent of specific hardware (CPU) architectures.
