IT Fundamentals Quiz

Study Notes

Data Analytics

Definition: The process of extracting insights and patterns from data to inform business decisions.
Key concepts:
- Data mining: discovering patterns and relationships in large datasets.
- Data visualization: presenting data in a graphical format to facilitate understanding.
- Predictive analytics: using statistical models to forecast future outcomes.
Tools and techniques:
- Data warehousing: storing data in a central repository for analysis.
- Business intelligence: using data to inform business decisions.
- Machine learning: using algorithms to identify patterns and make predictions.

Database Management

Definition: The process of designing, implementing, and maintaining databases to store and manage data.
Key concepts:
- Data modeling: designing the structure of a database.
- Data normalization: organizing data to minimize redundancy and improve data integrity.
- Database performance tuning: optimizing database performance for efficient data retrieval.
Database types:
- Relational databases (RDBMS): storing data in tables with defined relationships.
- NoSQL databases: storing data in a variety of formats for flexible schema design.

Network Security

Definition: The practice of protecting computer networks from unauthorized access, use, disclosure, disruption, modification, or destruction.
Key concepts:
- Firewalls: controlling incoming and outgoing network traffic based on security rules.
- Encryption: protecting data in transit using secure protocols (e.g., SSL/TLS).
- Access control: restricting user access to network resources based on identity and permissions.
Threats and vulnerabilities:
- Malware: malicious software designed to harm or exploit computer systems.
- Phishing: social engineering attacks to trick users into revealing sensitive information.

Artificial Intelligence

Definition: The development of computer systems that can perform tasks that typically require human intelligence.
Key concepts:
- Machine learning: training algorithms to learn from data and make predictions or decisions.
- Natural language processing (NLP): enabling computers to understand and generate human language.
- Computer vision: enabling computers to interpret and understand visual data from images and videos.
AI applications:
- Chatbots: conversational interfaces for customer service or support.
- Recommendation systems: suggesting products or services based on user behavior and preferences.

Cloud Computing

Definition: The delivery of computing resources and services over the internet on-demand and pay-per-use basis.
Key concepts:
- Infrastructure as a Service (IaaS): providing virtualized computing resources over the internet.
- Platform as a Service (PaaS): providing a complete platform for developing and deploying applications.
- Software as a Service (SaaS): providing software applications over the internet.
Cloud deployment models:
- Public cloud: sharing resources with other customers in a multi-tenant environment.
- Private cloud: dedicated resources for a single organization.
- Hybrid cloud: combining public and private cloud resources for flexibility and scalability.
