Study Notes
Programming Fundamentals
- Programming involves writing computer code to create programs that solve problems.
- Programs are sequences of instructions directing the computer on actions and how to perform them.
- Programs are created based on algorithms.
- Algorithms are step-by-step logical instructions for tasks.
- Algorithms are often represented as pseudocode or flowcharts.
- Pseudocode uses plain English to outline program instructions.
- Flowcharts use diagrams with boxes to illustrate program steps.
- Programming translates algorithms into computer programs.
- Programs must be detailed to guide the computer on precise actions to be performed.
- A program implements an algorithm step-by-step.
- Programming languages are artificial languages understood by computers.
- Programming languages consist of statements forming instructions.
- Instructions perform actions for the computer.
- Programming languages differ in complexity.
- Popular programming languages include BASIC (Beginner's All-purpose Symbolic Instruction Code) and examples like Python, and Scratch.
- BASIC is a general-purpose, high-level language.
- Python uses abbreviated sentences with lowercase words for instructions.
- Scratch uses graphical blocks and diagrams for instructions.
- Scratch relies on dragging and dropping colored blocks to create program actions.
- Programming languages are designed for human understanding and writing.
- Programs need translation to machine code before computer execution.
- Machine code represents instructions in binary or hexadecimal for hardware understanding.
