Study Notes
Introduction to Computer Science
- Computer science focuses on understanding computers and computing.
- The field encompasses theoretical and algorithmic foundations, hardware and software, and uses for information processing.
- Key areas of study within computer science include algorithms and data structures, computer and network design, information process modeling, and artificial intelligence.
- Computer science draws upon mathematics and engineering, integrating techniques from areas like queueing theory, statistics, and electronic circuit design.
- Computer science relies on hypothesis testing and experimentation during the development and refinement of algorithms, data structures, and computer architectures.
- Computer science is part of a broader discipline of computing, which includes:
- Computer engineering
- Information systems
- Information technology
- Software engineering
- These disciplines are connected by their focus on computing but maintain distinct research perspectives and curriculum emphases.
Computer Science Disciplines
- Major subfields within computer science include:
- Computer architecture
- Programming languages
- Software development
- Computational science
- Graphics and visualization
- Human-computer interaction
- Databases and information systems
- Networks
- Social and professional issues related to computer science practice.
- These subfields frequently overlap with other modern fields, showcasing computer science's interdisciplinary nature.
Computer Science Careers
- Computer science degrees provide a foundation for various career paths, including:
- Software development
- Computer programming
- Network systems administration
- Hardware engineering
- Video game design
Problem-solving Techniques
- Problem-solving is central to computer science.
- Programmers translate human problem-solving approaches into computer algorithms.
- Understanding programming language syntax is essential for implementation.
- Choosing the right programming language depends on project requirements, including scalability, performance, security, and compatibility.
Flowcharts
- Flowcharts visually represent workflows or processes using boxes connected by arrows.
- They illustrate how information flows through a process and are used in analyzing, designing, documenting, and managing processes/programs.
- Common flowchart symbols:
- Flowline: Shows direction of process flow.
- Terminal: Indicates start or end of flowchart.
- Process: Represents a step in a process.
- Decision: Represents a point where different paths can be taken based on a condition.
- Input/Output: Indicates inputting or outputting external data.
- Annotation/Comment: Provides additional information about a step.
- Predefined Process: Shows a named process defined elsewhere.
- On-page Connector: Used to replace long lines on a flowchart page.
- Off-page Connector: Used when the target is on another page.
- Delay: Represents a delay period in a process.
- Alternate Process: Shows an alternative to the normal process step.
- Data: Represents data input or output.
- Document: Represents a document.
- Multi-document: Represents multiple documents.
- Preparation: Represents a preparation step.
- Display: Represents a machine display.
- Manual Input : Input of data or information into a system.
- Manual Operation: Manually performed process step.
Pseudocode
- A step-by-step description of an algorithm using plain language.
- Serves as an intermediate step between an idea and its implementation in a high-level language.
- Benefits:
- Easy to understand.
- Saves time by catching errors early.
- Improves communication between developers.
- Flexible, not bound by specific programming language rules.
How to Write Pseudocode
- Identify the problem and its requirements.
- Break the problem into smaller, manageable parts.
- Write out the steps needed to solve each part in plain language.
- Test the pseudocode by walking through each step.
- Refine and revise the pseudocode as needed.
