Study Notes
Introduction to Computer Science
- Computing professionals develop computer applications addressing human needs.
- They create models, algorithms, and programs to represent and manipulate information.
- Not all computing professionals write code; some manage teams, support clients, or administer systems.
Models, Algorithms, and Programs
- Models: Abstract representations of real-world environments using logic and math.
- Examples include computer game objects, stock market metrics, or biological organs.
- Algorithms: Step-by-step instructions to manipulate information within a model.
- They are like recipes, defining specific operations.
- Algorithms achieve desired outcomes when executed.
- Programs: Implement algorithms in executable languages.
- Programs use languages that computers understand.
- Algorithms are in a human-readable form for our comprehension.
Tools of the Trade
