Explanation

Cassandra is a column-oriented (wide-column) NoSQL database, where data is stored in column families.

It is designed for high scalability, high availability, and fast writes across distributed systems.

Explanation

A clustered index determines the physical order of data rows in a table.

Because data is stored in this order, it can significantly improve range query performance.

Explanation

Third Normal Form (3NF) eliminates transitive dependencies, where a non-key attribute depends on another non-key attribute.

It ensures that all non-key attributes depend only on the primary key, improving data integrity.

Explanation

Vector data can result in large file sizes when representing highly detailed or complex geometries.

This can make storage and processing slower compared to simpler datasets.

Despite this, vector data is excellent for precise location and network analysis.

Explanation

GIS layering allows users to overlay multiple datasets (like roads, rivers, and land use) for spatial analysis.

Each layer represents a different type of geographic information.

Layering enables complex map creation and decision-making by combining various spatial data.

Explanation

Remote sensing data is collected using sensors mounted on satellites or aircraft to capture information about the Earth’s surface.

It allows monitoring of large areas without physical contact.

Remote sensing is widely used in weather forecasting, agriculture, and environmental monitoring.

Explanation

A raster dataset is made up of a grid of cells (pixels), each storing a value representing information like elevation or temperature.

It is commonly used for images, satellite data, and continuous surfaces.

Raster data is ideal for spatial analysis involving continuous phenomena.

Explanation

Copilot is an AI assistant available across the Microsoft 365 suite (which includes Word and Excel) to help with tasks like generating text, analyzing data, and automating workflows. 

Explanation

Several platforms use AI to help generate email text.

These platforms use large language models (LLMs) such as

• OpenAI (GPT models),
• Google (Gemini)
• Anthropic (Claude). 

Explanation
