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

A pie chart is best suited for showing the proportion of parts to a whole.

As it visually represents data as slices of a circle.

It highlighting the relative sizes of components.

Explanation

Media Compression in applications like PowerPoint reduces the size of audio and video files in a presentation.

This helps optimize file size for sharing and storage.

Compression can be done at different quality levels to balance size and media clarity.

Explanation

VLOOKUP requires a table array, the lookup value, and the column index number to retrieve corresponding data.

It searches vertically in the first column of the table array.

An optional range_lookup argument can specify exact or approximate matches.

Explanation

Read Mode in Word is designed to make reading documents easier by optimizing layout and hiding editing tools.

It provides a clean, book-like view for better focus.

Users can still highlight, search, and navigate in Read Mode without switching to editing view.

Explanation

Quick Parts allows users to store and reuse preformatted text blocks, fields, or document elements in Word.

It helps save time and maintain consistency in documents.

Quick Parts can include AutoText entries, document properties, and field codes for advanced use.
