Computer Data Representation Flashcard

Front

How do computers represent data such as numbers, characters, and colors?

Back

By grouping bits to create abstractions that represent various types of data.

Front

Why is it necessary to combine data from multiple sources?

Back

It provides a more complete picture by filling in gaps and reducing bias.

Front

How can a program help extract meaningful insights from a dataset?

Back

By automating tasks like filtering, sorting, and visualizing data.

Front

What is the primary difference between lossy and lossless compression?

Back

Lossy compression permanently removes some data, while lossless compression allows the original data to be perfectly reconstructed.

Front

What is metadata?

Back

Metadata provides additional information about data, such as the creation date or file size.

Front

What is binary representation?

Back

Binary representation is a way of encoding data using only two symbols, typically 0 and 1.

Front

What is the purpose of data compression?

Back

Data compression reduces the size of data to save storage space and improve transmission speed.

Front

What is the difference between structured and unstructured data?

Back

Structured data is organized in a predefined format, while unstructured data lacks a specific structure.

Front

What is an example of lossy compression?

Back

JPEG image format is an example of lossy compression.

Front

What is an example of lossless compression?

Back

PNG image format is an example of lossless compression.
