Understanding Computer Science

Computer scientists are in high demand due to the widespread use of computers.
Their role is to create and maintain tools that support and enhance computer usage.
Effective tools demand modeling before implementation.
Models are often mathematical in nature, commonly using existing structures like sets, lists, and orderings.
Theoretical frameworks are critical, forming the foundation for tool development.

Definitions of Computer Science

Computer science involves studying algorithmic processes that transform information, encompassing analysis, design, implementation, efficiency, and application (automation).
The discipline covers computer building, programming, computational tool usage, and knowledge derived from these activities.
Problem-solving computationally involves defined steps.

Steps in Computational Problem Solving

Abstraction: Building simplified models based on real-world problems.
Automation: Automating model solutions/operations using algorithms.
Implementation: Applying models and algorithms as code/instructions to be executable by a computer.

Examples of Abstraction

Car functionalities: Focus on exterior operations without internal engine details.
